Coast to Coast Collapses Demonstrates Need For Deck Maintenance

Another deck collapse recently made the headlines; this time from a family gathering at a seaside vacation home at Emerald Isle, NC on July 4th, 2015. This instance took 26 family members down with the deck when it failed, sending 16 people to hospital with emergency responders and another 4-6 people from private transport. At least 5 of the injured parties were in critical condition. It was supposed to be a happy occasion intended to be captured by camera but instead became a nightmare its victims would like to forget.

According to the final report from Emerald Isle town manager (link to official press release below), 26 people were injured in the collapse. A building official concluded that corroded fasteners were the primary contributor that brought the 8-foot by 10-foot section of deck crashing 9 feet to the ground.

This follows last month’s horrific Berkley balcony collapse that claimed the lives of 6 of the 13 students that occupied the 4th floor balcony when it detached from the building. In this instance, the balcony reportedly detached from the building and swung down at a 90 degree angle sending all of its occupants to the ground below. A Berkley Building and Safety Division inspector said the deck’s severed joist ends looked “extensively rotted”. The outer beams of the balcony had sustained “significant rot and decay”. CNN succinctly summarizes this story and the findings in the official report.

It’s an all-too-familiar story of summer celebration turning tragic and why Duradek is an active supporter of the North America Deck and Railing Association’s Deck Safety Program. This deck safety initiative was created to increase public awareness on deck safety issues as well as provide some very useful tools for both consumers and professionals on deck evaluations and maintenance.

Deck maintenance is not just to keep your outdoor living space attractive. Deck waterproofing is critical in maintaining the structural integrity of your deck.


See page 31 in the online magazine for "Three
Common Deck Collapse Factors..."

From west coast to east coast, the contributing factors to deck collapse are often the same and Duradek addressed these issues in Landlord BC’s ‘The Key’ publication in the summer 2015 issue with “Three Common Deck Collapse Factors and How to Avoid Them” (.pdf).

In most deck collapse occurrences, the decks were originally built to code, but water infiltration and its resulting damage appear to be the primary contributors to the collapses. Weakened wood from dry rot and fasteners disintegrated by corrosion would leave any deck unable to support the load it was originally built to sustain.

It is important to remember that while a deck is a cherished part of the home, its maintenance requirements are very different from most other parts of the home as it is the only load bearing part of the home that is under constant exposure to the elements.

In the final Emerald Isle report, town manager Frank Rush wrote, “North Carolina General Statures do not currently grant authority to NC cities and counties to conduct periodic building code or deck inspections of vacation rental units. Routine inspections of vacation rental units / exiting homes are the responsibility of the property owner and / or property management company.”

See the Emerald Isle final press release on the incident that includes building official’s findings, as well as police and emergency responders’ official incident reports (http://www.emeraldisle-nc.org/pdfs/PressRelease07072015-DeckCollapseFinalReport.pdf), or an overview of the story on Emerald Isle Deck Collapse on the WNCN.

Duradek vinyl deck membranes have been waterproofing decks and balconies for over 40 years. With this experience we know that when it comes to waterproofing, it is all in the details which is why Duradek is not available as a do-it-yourself product. Deck waterproofing is a specialty trade and general contractors may not have a full understanding of the specific details and techniques required for long lasting deck waterproof integrity.

To speak to a Duradek professional installer about your decking project, look for a Duradek Dealer in your area for a no obligation estimate.

Building a Deck that Meets Code

While building a deck for your home may seem like a fun, do-it-yourself project, the truth of the matter is that deck construction is a specialty trade. Even general contractors with plenty of building experience may not have the specific knowledge and experience required to construct a structurally safe and attractive deck that meets building code.

There are a number of International Residential Code requirements that are specific to building a safe deck that are not required for most other areas of a home. Decks have two very distinctive and significant contributors to make them such a unique feature requiring special consideration:

1 – The density of occupants on a deck are often far greater than in any other part of the home.

2 – The deck is the only a load-bearing pedestrian surface of a home that is under constant exposure to the elements.

These two factors combined make building codes critical to ensuring the safety of a deck’s future occupants – not just in how the deck is constructed, but also in what materials are used. Whether you are motivated by protecting your family or by reducing potential liability, the following information is critical in building a deck.

The Two Most Important Code Resources for Deck Builders

1 – ICC Approved International Building Code Resource Book

2 – ICC Approved Product Evaluation Reports

International Residential Code (IRC) Reference Book for Deck Building

While the 2015 IRC is complete, many jurisdictions still rely on the 2009 IRC as their standard. Deck builders have the distinct advantage of the availability of a specific Deck Construction Code Book written by one of the industry’s key players, Glenn Mathewson. Glenn Mathewson is an active North America Deck & Railing Association (NADRA) member and is one of the most knowledgeable professionals in the decking industry. He produced the Deck Construction Code Book in partnership with the North America Deck & Railing Association (NADRA) and the International Code Council (ICC).



This specialty reference book takes all decking related code out of the cumbersome 2009 IRC (an 868 page book with decking references in multiple sections) and reduces it down to a concise 270 page decking reference that is much easier for decking professionals to understand. It includes photos and commentary from Mr. Mathewson as well as exact printed reference of the 2009 IRC codes.

International Code Council (ICC) Product Evaluation Reports

Using the right products for your deck building projects is just as important as the construction methods used to ensure a safe and reliable deck. When you are planning your projects and selecting the products to be used, be sure to review a copy of the product’s ICC-ES Report.

When a product has an ICC-ES Report you can see first-hand what specific use(s) for which the product has been evaluated, as well as any products it is used in conjunction with, its installation requirements and what kind of 3rd party testing was conducted to prove its suitability for a particular use.

It is important to note the distinction between an ICC-ES Listed product vs. an ICC-ES Evaluated product which goes through a much more rigorous testing procedure.

Duradek, another industry leader and proud NADRA member, has been around long enough to know the importance of having the performance based ICC-ES Evaluation Report. Duradek’s evaluation (ICC-ES ESR-2151) proves the effectiveness of Duradek’s performance as both a roofing membrane and a pedestrian traffic coating to give our customers the peace-of-mind to know the product will perform as it is intended.

To help our customers and future customers understand and use ICC-ES Reports to their full advantage, Duradek Technical Manager, Len Viegener has produced a couple of easy-to-follow pieces to educate even the most non-technical minded individuals on the value of these reports and how to read them. With a unique product like vinyl deck membranes that does not have its own specific evaluation criteria but instead relies on two distinctly separate evaluated features (in this case, traffic coating and roofing membrane) it is even more important to understand what to look for and why.

The latest document, “Why is an Evaluation Report so Important” breaks down what material standards apply, which building code authority has jurisdiction over those standards and how that leads to the final evaluation report.

Duradek Recaps Deck Safety Month's Dangerous Decks

Deck safety awareness is an important topic for anyone that owns, resides in or visits properties that include the desirable feature of a deck or balcony; yet a topic that often gets a mere nod of acknowledgement but little focussed effort.

Decks are traditionally a favourite place to gather, particularly in the summer months, and each year we hear of people suffering needlessly from trauma and injuries resulting from deck collapse. Just within the last few weeks alone there were two reported deck collapse incidents.

On May 16, 2015 in Lithonia, GA there was a sudden deck collapse when friends and family were gathered after a wedding, injuring 9 people – 7 of whom were hospitalized. Officials say that old, dry-rotted wood that was only held up by nails and not proper fastening bolts were the main contributors.



View deck collapse video coverage on CBS46 News

On May 16, 2015 in Noblesville, IN there were 12 people on a deck that collapsed sending 2 to hospital. This wide-spread, ongoing issue prompted the North America Deck & Railing Association (NADRA) to launch the Check Your Deck initiative and designate May as annual Deck Safety Month.

Duradek is proud to be a Deck Safety Ambassador to help further awareness of deck safety issues and to encourage both consumers and builders to use the excellent free resources for deck safety that NADRA offers on their website. Valuable tools like the Deck Evaluation Form and Consumer Checklist can help you to identify the trouble areas to ensure your deck is not at risk of collapse.

Using these tools and taking the steps necessary to check your deck goes a long way to ensure the safety of your family and friends.

Just ask consumer deck safety advocate Jeremy Wilt has been educating the public after he and his family experienced a traumatic deck collapse a year and a half ago. Jeremy has taken on the mission to spread the message of safety and prevention through a series of YouTube videos. The video from WMC Action News featured below shows shocking footage of the collapse that occurred at the clubhouse of Wilt’s New Albany subdivision during a Christmas Party.



Other recent deck collapse incidents include:

On April 30, 2015 in Cedarville, OH 8 people were victims of deck collapse.

On April 20, 2015 in Knoxville, TN a balcony collapsed at an apartment complex sending 1 woman to hospital and prompting an emergency repair work order on 100 other decks in the complex which were very old, wooden decks not well-maintained.

As Deck Safety Ambassadors, Duradek would like to remind you that maintaining a wooden deck by resealing each year is not just for aesthetic purposes…it is to keep the wood protected and reduce the chance of water infiltration and wood rot.

To reduce the time, effort and cost on deck waterproofing maintenance, consider the advantages of Duradek vinyl decks for your home. Duradek will protect the wood of your deck with a completely water-tight seal and Duradek’s professional installation techniques will help protect the entire home by considering the building envelope and preventing water intrusion at the critical areas where deck meets house.

If you’d like to speak to a decking professional about your deck, contact one of Duradek’s trained and authorized installers in your area.

Best Spring Deck Maintenance Advice - Part 1: Inspections

Ah, spring time! Already here for some parts of the country...just around the corner for others, early spring is the time to start preparing our outdoor leisure areas for a satisfying season of sun and fun. For those of us with sundecks or balconies, that means spring deck maintenance time and crossing our fingers hoping we don’t hear that ugly 4-letter word – “LEAK”.

The first priority....finding out how hard winter actually was on our decks and balconies. The single most influential factor in reducing high maintenance costs is to be sure the waterproofing is intact and the building envelope is still protected to avoid unexpected water infiltration and resulting damage. Whether you have a small balcony or expansive roof deck, significant and costly repairs due to leaks and water intrusion can often be avoided with simple annual maintenance and inspections.

Inspection Checklist for Decks and Balconies

It is important to check all deck perimeter details
are securely in place and repair if needed.

Perform your annual spring deck inspection with this easy-to-follow checklist:

• Inspect for ice or wind damage: gutters that have pulled away from the building, separation of the gutter seams, etc. Fix or replace as needed.
• Check flashing where the deck and the house meet and along the deck perimeter to ensure it is still securely in place without any damage or deterioration and fix as needed.
• Check doorways and other entryways to ensure all sealing or caulking is still in place.
• Check any caulk at perimeters or posts and re-caulk where it is missing or worn away.
• Look for loose or cracked trim, signs of decay or insect damage.
• Check the deck slope. Over time, the main building or the deck structure may settle, shrink or shift causing cracks or points of vulnerability. Be sure the deck slopes away from the building to avoid pooling water adjacent to the building or entryways.
• Check the stability of the wood in several different areas where applicable, including deck boards, stairs, support posts and joists under the deck and ledger board (where the deck attaches to the house). Look for small holes in the wood that may indicate insect damage is present.
• When checking wood, pay special attention to areas that tend to remain damp, are regularly exposed to water or are in contact with fasteners. If you are uncertain of the condition of the wood, use a tool like an ice pick or screwdriver to attempt to penetrate the wood surface. If you can break off a sliver of wood without splinters, easily penetrate to ¼- ½ inch or find that the wood is soft or spongy, decay may be present.
• Check exterior outlets and faucets for cracks or leaks and repair as needed.
• Inspect any vents for openings to prevent rodent intrusion.
• Check curbs or retaining walls for shifting or damage.
• Inspect all railings for rot, loose bolts or caulking and fix as needed. Railing maintenance can be significantly reduced by choosing aluminum over wood.

Check the area around any posts...a common
spot for water infiltration which can lead to rot.

Areas of Concern? Call a Professional

Of course, general stability of the deck structure and a protected building envelope are the most important concerns. If during your deck inspection you have noticed any structural issues or suspect there may be water damage, you will be best served by contacting a professional to assess the situation. It is to your advantage to gain the peace of mind that your home is protected and your family is safe, happy and will continue to enjoy your outdoor leisure space.

It is critical that you properly waterproof to protect the building from eventually being compromised by water damage. (See more about maintenance and waterproofing on our next post, "Best Spring Deck Maintenance Advice - Part 2: Maintenance").



Inspect your deck in the spring to have a leisurely, worry-free summer.

3 Key Tips for Deck Care in Winter

Keep your vinyl deck safe and attractive throughout winter and beyond with these 3 important tips:

While we are inching our way through winter, many regions with heavier than normal snowfall are dealing with digging their way out of the white stuff more than most years. Dreams of barbecues on the deck have taken a back seat to the realities of ice and snow, but snow management on your deck is a breeze with a Duradek vinyl deck.

Snow on a Duradek is easy to manage.

Winter Vinyl Deck Tip #1 - Use Only a Plastic Snow Shovel

It's no problem at all to shovel snow off of your deck and the textured surface can easily withstand contact with a plastic shovel, but just be sure to avoid snow shovels with metal edges that allow the risk of puncturing your vinyl membrane. Duradek vinyl is an extremely reliable waterproofing solution, but if it is compromised with a puncture or tear moisture can penetrate through to the structure. While repairs are possible, if a puncture has gone unnoticed for an extended time, it may lead to a larger repair.

Always use a plastic edged snow shovel on a vinyl deck.

Winter Vinyl Deck Tip #2 - Use De-Icing Agents

Duradek vinyl is textured for slip-resistance, but with a layer of ice on top, it can be as slippery as any other pedestrian surface. We want you to safely enjoy your deck all year, so rest assured you can use a variety of snow and ice melting solutions on it without concern. Rock salt, snow melting chemicals and even kitty litter for non-slip traction is perfectly safe to use (just be sure to use traditional, course kitty litter for non-slip traction, because if you mistakenly use the fine-sand clumping cat litter, you will wind up with a heavy, muddy mess to clean up).

De-icers are safe to use on Duradek.

Winter Vinyl Deck Tip #3 - Rinse Well When the Season Changes

To get the most longevity in your deck's appearance, be sure to give it a wash with soap and water after winter, including a very thorough rinse to be sure to remove any chemical residue from de-icers or soap. While the chemicals from de-icers do not damage the vinyl surface when applied, if a chemical film is left on the surface from de-icers or cleaning agents, direct sun can bake those chemicals into the vinyl which is harmful and will affect your deck’s appearance.

That’s all there is to it! Now you can be confident in taking all precautions available to keep your deck clear of ice and snow through the remaining winter months and look forward to the return of the warm weather to get back to really enjoying your deck again.

The area below a Duradek deck has the advantage of roof
grade waterproof protection to keep it dry below your deck.

The Advantages of Duradek Walkable Rooftop Deck and Waterproofing Vinyl in the Winter

Those of you who have a deck protected with Duradek vinyl membranes have an attractive and low maintenance decking solution throughout the year and winter is no exception. Duradek vinyl allows for easy and worry-free winter deck care. PLUS - if your Duradek vinyl is on a second level deck....you've got a protected, dry area underneath. Even with a heavy snow, Duradek keeps the lower decks clear for use and you can still enjoy a little outdoor living space when the snow has covered everything else.

Water Absorption, Lateral Loads and Deck Collapse Risk

When deck collapse tragedies happen there is not always a clear-cut reason. It is mostly speculation of what caused the collapse, but here we look at two significant contributors and how you can prevent the chances of it happening to your deck.


Earlier this June there was a rather dramatic deck collapse in Pawleys Island, SC when a group of 25 – 30 people simultaneously gathered on a deck to take a photo in front of a rather impressive double rainbow. Although a rainbow is an innocent and inspiring motivation for a group selfie, this rainbow lured the unsuspecting group to a tragedy on an otherwise enjoyable day.

Have You Checked Your Deck? May is Deck Safety Month

Ahhhh, May! That favourite time of year when we really begin preparing our outdoor living areas in anticipation of the barbecues, games and luxurious lounging that is sure to follow in the coming summer months.

Having been around for 40 years with over 125 million square feet of vinyl decking installed throughout North America, Duradek wants to be sure that your deck is still the best it can be. While the obvious task of cleaning any organic debris, dirt and soil from the deck or patio surface is usually the first step for many home owners, be sure to include the critical step of a complete deck inspection.

Paying particular attention to the waterproofing details on and around your deck such as the caulking around posts and drains can help you isolate any vulnerabilities in your deck before weakening can occur or unfortunate accidents can take place.

 May is Deck Safety Month ®   
The North America Deck & Railing Association (NADRA) is the decking industry's most visible association, and they have a very strong consumer focus. Deck safety is a critical issue to NADRA, and the organization has a mandate of increasing public awareness of the necessity of regular inspections and maintenance of existing decks, and proper installation of new decks. This initiative prompted NADRA to declare May as Deck Safety Month ® in 2006.

 

NADRA estimates that there are 40 million decks in the U.S. that are over 20 years old, which means they were installed prior to today's building codes. This makes deck safety a critical issue that must be addressed and NADRA helps to make it easy by providing a Deck Safety Consumer Checklist and a Deck Safety Evaluation Form for builders. This is a fantastic free tool for keeping all your deck renovation assessment details together and can be very handy to reference  when getting estimates or discussing project options. You can get both of these very handy free tools on the NADRA website.

 Deck collapses happen far too frequently and when they do happen, they happen fast. For example, the Christmas Party in Indiana in December 2013 where a group photo on the deck was interrupted as the deck gave way with no warning, sending two dozen family members crashing to the ground. The family released security footage of the collapse and it is startling to see how sudden and unexpected the collapse was.
See the footage of the deck collapse on YouTube.



More recently, in April 2014 another family photo resulted in five out of sixteen family members suffering injuries when they fell 10 feet to the ground when the deck collapsed on a deck at a restaurant in Ontario. This wooden deck appears to have been left unprotected from the elements and seems to be yet another unfortunate example of a deck weakened by water infiltration to the point of structural insecurity.

Duradek is proud to be a member of NADRA and takes deck safety very serious too. Whether you are located in Canada or the United States, ensuring your deck meets building requirements is critical which is one of the many reasons it makes sense to have your deck build by a decking professional. Right from the initial construction of the deck to the condition of the substrate, the application of the waterproofing and the installation of the railings, each stage requires its own detailed expertise and is a major factor for Duradek recommending that you do not do the job yourself.

If you are considering renovating your balcony or deck to ensure your family photos are all taken safely, one of our Duradek trained waterproofing specialists would be happy to provide you with a free estimate on your decking project.

Deck Collapse Causes And Prevention

While the well-defined peak season for reported deck collapses has passed (June-August), in the last couple of weeks there have been a couple more deck collapse stories to hit the media with a too-familiar story of unsuspecting folks gathered on a balcony or deck and finding themselves suddenly plummeting to the ground amidst the debris of the failed deck.

In Dartmouth, NS 16 people were on a deck at a party when it collapsed with 2 people standing underneath the deck at the time. Four people were seriously injured. See full article on the Chronicle/Herald website.

In Boston, MA about a dozen fine art students gathered on a 3rd-floor balcony at an art opening were suddenly and unexpectedly crashing down to the 2nd-floor deck. Luckily, nobody was seriously injured. See full article on wcvb.com.

What Causes Decks to Collapse

Initial responses for inquiries on what causes a deck collapse are commonly quick to question if the deck was built to code with proper permits and inspections but it appears that most times there is no negligence in that area.

While there are several possible reasons for the deck failure, more often than not, the failure is attributed in some way to the ledger board that connects the deck to the building structure.

The connecting hardware securing the deck to the house is often the first item to be checked. While inexperienced deck builders may use inadequate nails to secure the deck ledger board to the rim joists of the house, more often than not the correct anchoring fasteners were used. What then causes the fasteners to pull away from the house? Often the culprit is wood rot. When water invasion has weakened the wood to the point of softening or rot, no fastener is able to perform securely.

Waterproofing for Safety

When some homeowners (and inexperienced deck builders, for that matter) think about deck waterproofing, the focus of the consideration is often the deck surface or the railings and the esthetic value waterproofing brings to outdoor living space. Sadly, it is the critical inside perimeter waterproofing details that are neglected that can allow water to infiltrate the deck components and the building envelope which can compromise the structural security.

Many times, water intrusion and wood rot is discovered before weakening to the point of collapse and the deck can be salvaged, but sometimes the water damage goes unnoticed. When this happens for too long, eventually the rot will deteriorate the wood until the deck becomes unsafe (This seems to be more common in circumstances where the owner or manager of the property is not the primary resident, such as in the vacation beach home deck collapse in Ocean Isle Beach, NC in July this year).

When water invades a deck's substrate, it can literally
crumble under the surface.

For example, see Duradek Case History #151 where the inside perimeter waterproofing details were previously neglected and threatened the structural integrity of the deck. Luckily it was noticed and repaired in time to salvage some of the deck, and most importantly, avoided deck collapse and injury.

If you would like to have a Duradek waterproofing professional provide a free estimate on renovating your deck, contact a Duradek dealer in your area.

Deck Autopsy: The Cause of the Collapse

Two weeks after the high profile deck collapse in Ocean Isle Beach, NC the speculation continues on what caused the sudden collapse that sent 21 family members to hospital after attempting a group photo on the deck of the ocean front vacation home. While 25 family members were gathered on the deck, it suddenly gave out and everyone from the infants to the elderly crashed down with the debris to the concrete patio below. Fortunately, there were no fatalities but several traumatic injuries left this family with far different vacation memories than they were hoping to create.

There are several theories on what may have caused the deck to collapse and while this is not a forensic report of the actual cause on this particular collapse, we are going to look at the possible contributors and what you can do to prevent this kind of tragedy on your deck.

Possible Causes of Deck Collapse

Not Built to Code – Not Likely
This deck was inspected when it was built in 2003 so it was built to state building code laws. Although further deck inspections are not a legal requirement unless requested, Ocean Isle Beach Mayor Debbie Smith says, “These oceanfront decks need to be held to a higher standard than North Carolina laws require.” This comment addresses the environmental contributors for decks in any coastal community such as high salt content in the air and heavy winds.

Overloading – Possible, But Unlikely
While the possibility of too much weight for the deck has been discussed, in the case of the Ocean Isle Beach collapse it is unlikely. North Carolina Building Inspectors Association President Glenn Batten says that the deck should have held that many people. State law requires a deck to be built to support 40 lbs per square foot, but to accommodate other features like hot tubs or heavy planters, decks are often built to accommodate 50 – 100 lbs per square foot.

Storm Damage – Possible
Glenn Batten goes on to say that the fact the deck collapsed tells him the deck may have suffered hurricane damage. Fasteners could have been pulled and stretched to their limits. While this is not necessarily the main contributing factor in this case, again it brings the environmental factors into the equation where heavy winds and salt air can age a deck much quicker than in inland areas and require more maintenance and commitment to regular annual inspections.

Wood Rot – Most Likely
The video footage of the resulting collapse of this deck seems to indicate that the ledger board and framing of the deck remained intact, but the central collapse of the deck boards indicates that supporting joists were the most vulnerable.

Contributing Editor for Professional Deck Builder Magazine, Kim Katwijk has been tracking deck collapses for 4 years and researching back a further 9 years. Kim says there are two main reasons for deck failures.

1 – The ledger: (the board that runs parallel to the side of the house and supports the edge of the deck, securing it to the house) is just nailed onto the house. Half the weight of the deck is on the ledger board and nails have a tendency to slide out over time.



All wood - even treated wood - will rot if not protected.
Wait too long to waterproof your wood deck, and
you will be rebuilding it.

2 – ROT!: Decks that have not been built correctly or have not been maintained are more susceptible to damage and weakening due to rot. Look for rot’s discoloration in the lumber or anything growing out of the wood. Test for rot by stabbing the wood with a sturdy knife point. If your knife goes in more than one quarter of an inch or you find spongy spots, that means the wood is decaying. If only a few boards are damaged, replace them. You cannot get away with leaving the rotten boards and putting a new board beside it. This will only accelerate the rot by providing fresh food for it. The rot will quickly invade the new board. If you find soft spots in the support posts or beams, you will need to rebuild the deck. (This requires a building permit.) To minimize future problems, hire a professional that specializes in decks. (see link at the bottom of post for helpful tips on selecting a decking contractor.)

Kim Katwijk also advises, “Assess whether the structure is solid. When you walk on the deck, you should not feel it move. It should not tilt. The railing should be firm and not moveable. The fasteners should not be loose or corroded. If you own a wood deck, you should clean and seal the boards every year.”

If annual maintenance like sanding and sealing your wood deck is not something you can realistically commit to performing, you may want to consider an alternate option that has proven successful waterproofing results to keep your deck safe from wood rot.

Party on the Patio Safely - Do it With Duradek

Summer is officially here! And one of the best parts of summer is enjoying your balconies, decks and patios in the fantastic summer weather. It doesn't seem to matter if you prefer a quite lounge with a good book or if you enjoy a lively social barbecue; your outdoor living space is the ideal place to be for the next few months. Duradek wants to make sure all the memories you create on your deck are good ones.



Coastal decks constantly exposed
to moisture are most vulnerable
to weakening due to improper
waterproofing. With Duradek,
protection is guaranteed.

With the growing trend of your outdoor living space being an extension of your home, at any time of year balconies and decks are the most popular places for people to congregate, but particularly during the summer months. Can your deck handle the load?

This is particularly important to consider if you live in a coastal region where moisture can deteriorate your deck's integrity if not properly waterproofed. One of the most tragic elements of deck collapse stories is that usually they can be avoided by proper deck maintenance and common sense, but in some instances, neither is present and the price is paid with person injury (and sometimes resulting litigation).

Take for example, a spring-break celebration where several college students suffered from injuries resulting from a deck collapse at a beach house party. A combination of aging and deteriorating wood and over-loaded weight was likely the main contributors to the collapse.

But a group of crazy college kids partying on a balcony is not the only time a deck is at risk of collapsing. In Birmingham, a church luncheon on a residential deck also resulted in a collapse and personal injury.

If you are aware of deck safety concerns, you have probably already performed your annual deck inspection as recommended by the North America Deck and Rail Association (NADRA). If deck safety is something you haven't considered, think about this...according to NADRA there are approximately 40 million decks in North America that are over 20 years old. Most of those decks aren't built to today's building code standards, and combined with aging factors and possible water damage weakening the structure, deck safety may be a topic you want to consider.

If you are questioning the safety or stability of your deck, have a qualified decking professional like a Duradek trained waterproofing specialist come take a look at your deck. You can request a free estimate on ensuring your deck is stable and protected with Duradek, the original vinyl deck waterproofing membrane.

Practice Safe Decks this Season

It's that time of year again when those of us with decks and patios have been excitedly preparing our favorite outdoor living areas in anticipation of the barbecues, games and luxurious lounging that is sure to follow in the coming summer months.

Having installed over a million square feet of vinyl decking, Duradek wants to be sure that your deck is still the best it can be. While the obvious task of cleaning any organic debris, dirt and soil from the deck surface is usually the first step for many homeowners, be sure to include the critical step of inspecting the waterproofing details such as the caulking around posts and drains.

May is Deck Safety Month ®  

The North America Deck & Railing Association (NADRA) is the decking industry's most visible association, and they have a very strong consumer focus. Deck safety is a critical issue to NADRA, and the organization has a mandate of increasing public awareness of the necessity of regular inspections and maintenance of existing decks, and proper installation of new decks. This initiative prompted NADRA to declare May as Deck Safety Month ® in 2006.

As many decks remain that were installed prior to today's building codes, deck safety is an issue that is important to address and NADRA provides a Deck Safety Consumer Checklist and a Deck Safety Evaluation Form for builders. This is a fantastic free tool for keeping all your deck renovation assessment details together and can be very handy to reference  when getting estimates or discussing project options.

Duradek takes deck safety very serious too. Whether you are located in Canada or the United States, there are building requirements to consider in constructing your deck surface and preparing the substrate. Right from the initial construction of the deck to the condition of the substrate, the installation of the vinyl waterproof membrane and the installation of the railings, each stage requires its own detailed expertise and is a major factor for Duradek recommending that you do not do the job yourself.

Home Inspection Checklist Includes Deck Considerations from Duradek

The arrival of spring brings a bevy of home improvement ideas for many homeowners, but before you start compiling your wish-list, it is a good idea to perform a complete annual home inspection to ensure you don’t miss any important details and can properly prioritize your home improvement plans. Atlanta Home Improvement Magazine has given homeowners an advantage with a special section in their April issue and Duradek was happy to contribute some of the key deck considerations for your reference.

The ‘Spring Spruce Up’ (page 37) is a handy maintenance and repair checklist guide full of detailed information on the steps you need to properly provide your home with an annual inspection without missing a thing. This time of year it is particularly important to pay attention to your deck maintenance needs so your deck is safe, secure and ready for enjoyment through the sunny summer months.

Deck Inspection Advice

The folks at Duradek of Georgia are deck experts and members of the North America Deck and Railing Association (NADRA), so they know that deck safety is a primary concern.  On page 41, Duradek of Georgia mentions that with over 40 million decks in North America over 20 years old, homeowners would be wise to refer to NADRAs deck inspection checklist to dive even deeper into inspection and maintenance details for decking. It is important to ensure that any activities or enjoyment that your deck can bring to your family and guests are safe and worry-free.

Of course, general stability of the deck structure is the most important concern, but to ensure your deck structure stays strong you need to be confident that it is properly waterproofed to protect it from being compromised over time by water damage.

Deck Waterproofing

Duradek is the perfect solution for deck waterproofing since the PVC membrane provides a completely water-tight seal around your deck’s surface.  In addition, Duradek vinyl deck surfaces require no yearly maintenance like the sanding and staining a wood deck requires or the re-application of a liquid waterproof coating over a concrete deck. Whether you start with wood or with concrete, once Duradek has been installed you have guaranteed waterproof protection for 10 years.

In the image above which was included in April’s Atlanta Home Improvement Magazine, you can see how Duradek provides a beautiful, clean and contemporary look. But what it doesn’t show is that this deck also serves as a roof for the ground-level deck below. Not only does Duradek protect the deck structure, but the roof-grade protection of Duradek Ultra membranes ensures that anything below your deck is kept dry too.

How to Deal with Heavy Snow on Your Duradek Deck

Mother Nature has not been kind to everyone this winter. From the east coast to the Midwest, decks have accumulated much more than average snowfall.

While in the midst of brutal winter storms, your deck is probably not your first priority but it still will need to be made passable and safe until the spring weather and warmer temperatures make it your favorite place once again.

To get the longest life from your Duradek vinyl deck, we wanted to take a moment to remind you of how to best use and care for your deck with heavy snow conditions.

Duradek can handle heavy snow.

Winter Deck Care with Heavy Snow Fall

Duradek’s Walkable Rooftop Deck and Waterproofing Vinyl allows for easy and worry-free winter deck care. Duradek patterns and colors are beautiful all year round, but to ensure that you get the most longevity in your deck’s appearance when the wicked winter weather attempts to bury your deck under a mountain of ice and snow, we’ve got a couple of simple tips for you to follow.

#1 – Use Only a Plastic Snow Shovel

The use of metal snow shovels or metal edged snow shovels may risk puncturing your vinyl when you are digging into the snow...particularly with deep snow or thick ice that requires the use of extra force. Be safe, not sorry, and use only a plastic snow shovel on your vinyl deck.

#2 – Be Sure to Use a De-icer if You Walk on Your Deck in the Winter Conditions

While Duradek has some slip resistance built in to the vinyl, when covered in snow or ice it is going to be as slippery as any other surface covered with snow or ice. If your Duradek is at an entranceway or other area where you will traverse it during the winter months, please do not be hesitant to use a de-icing agent. Your Duradek can handle it and your safety always comes first.

#3 – If you Use A De-Icer, Be Sure to Clean it Off Before Spring

Though it is totally fine to use a de-icer on your Duradek vinyl deck, it is very important to clean your deck with soap and water, and rinse it off thoroughly before the spring and summer sunshine returns. The sun can actually ‘bake’ the chemicals into the vinyl surface and compromise its appearance, so be sure to clean and rinse off any de-icing agents used through the winter.

(Whether using de-icing agents or not, we would recommend a light seasonal cleaning to keep your deck looking fresh and to avoid heavy accumulation of dirt over time.)

So for all of the folks out there that have decks buried under snow…let’s hope the groundhog was right and winter is almost over!

The Most Overlooked Home Maintenance Task - Deck Inspections

Deck inspections are quite possibly the most commonly overlooked home maintenance task. Perhaps it is because it is an outdoor extension of a home’s living space, or perhaps it is due to its seasonality of active use. No matter the reason, it is critically important to perform this maintenance task regularly to avoid the dangerous risk of deck collapse.

The number of deck failures resulting in injuries is increasing at an alarming rate. According to the North America Deck and Railing Association (NADRA), there are over 40 million decks in the U.S. that are over 20 years old, which means they were built prior to current building code standards and may hold greater risk than newer decks. 

If that staggering statistic doesn’t encourage you to inspect your deck, take a look at this video from the NADRA Western Washington Chapter performing a simulated deck collapse.


NADRA offers a fantastic, free consumer checklist for deck inspections available for download from their website. They also offer a very thorough deck evaluation checklist for builders and inspectors to assist in the evaluation process.

While these documents can aid you in determining if you need to perform any repairs to your deck, there are a few things that should always be left to the professionals:

• Waterproofing a deck, especially a deck over living space
• Waterproofing under exterior tile
• Replacing a railing system by puncturing a waterproofing membrane

When it comes to waterproofing decks, patios and roof decks over living space, the performance is all in the details and we cannot stress enough the importance of utilizing the services of a deck waterproofing professional well versed in the intricate details involved in successful waterproofing of your outdoor living space.

Duradek Ultra walkable, waterproof vinyl membrane, Duradek Ultra Tiledek under tile waterproof membrane, and Durarail powder-coated aluminum railing systems are all available only through Duradek’s network of trained and authorized waterproofing experts.

Top 5 Deck Maintenance Tasks

While a properly built and waterproofed deck requires very little maintenance, it is no excuse to ignore deck maintenance or deck repair tasks all together. A very small amount of time is all it takes to avoid costly repairs, or worse, personal injury due to deck collapse.

Duradek Recommends Performing the Following Top 5 Deck Maintenance Tasks.

#1 TASK: General Deck Inspection

FREQUENCY (per year): once

DESCRIPTION:

1. Inspect your deck for any built-in or added on features to ensure they are functioning correctly and safely.
2. Be sure that all lighting is working, and clean all light covers to allow adequate light to shine through.
3. Ensure all electrical outlets, appliances and features are up to code and that there are no electrical cords presenting a tripping hazard.
4. Ensure that any sources of fire or heat such as fire pits, chimneys, grills, heaters and candles or placed safely away from flammable surfaces and protected by a non-flammable pad.
5. Test all outdoor furniture for stability.
6. Be sure to store all deck related chemical products away from children (i.e. barbecue fluids, cleaners, etc.).

POSSIBLE OUTCOME IF NOT DONE: deck safety may be compromised and could result in damage/expense to your deck or cause personal injury.

#2 TASK: Detailed Deck Inspection

FREQUENCY (per year): once

DESCRIPTION:

1. Check for stability of the wood in several different areas of the deck. Be sure to check deck boards (if exposed), stairs, support posts and joists under the deck and the ledger board (where the deck attaches to the house).
2. Inspect any caulking that has been used at deck/wall intersections, around any posts or protrusions, etc. for damage or openings, re-caulk as necessary.
3. Pay special attention to any areas that tend to remain damp, are regularly exposed to water or are in contact with fasteners.
4. Note: If you are uncertain of the condition of the wood, you can use a tool like an ice pick or a screwdriver to test the wood by attempting to penetrate the wood surface. If you can easily penetrate ¼ to ½ inch, break off a sliver of wood without splinters, or the wood is soft and spongy, decay may be present.
5. Look for any small holes in the wood that may indicate insects.
6. Check flashing along where deck meets house and along deck perimeter to ensure flashing is firmly in place.

POSSIBLE OUTCOME IF NOT DONE: deck stability and safety may be compromised, and worst case scenario could result in a deck collapse, extensive repairs and personal injury.

#3 TASK: Deck/Stair Railings Inspection

FREQUENCY (per year): once

DESCRIPTION:

1. Deck stairs should appear even without sagging and should not sway or move.
2. Check any railings or handrails to be sure they are firmly in place.
3. Check steps to be certain they are securely attached and not decayed.
4. Ensure all railing fasteners are in place and are not corroded.
5. In the case of decks waterproofed with a vinyl membrane, ensure all caulking around surface mounted posts are intact.

POSSIBLE OUTCOME IF NOT DONE: un-noticed water infiltration through even the smallest of entry points can cause eventual water damage and costly repairs, and unstable railings can cause personal injury.

#4 TASK: Deck Cleaning

FREQUENCY (per year): 4 times

DESCRIPTION:

1. The removal of any debris and proper cleaning is a crucial step in maintaining your deck’s appearance. Remove organic matter such as leaves or moss, which may become a slip-hazard.
2. Most times a mild household cleaner diluted in water and using a soft brush or broom for scrubbing, then rinsing thoroughly will remove dirt and freshen up your deck’s appearance.
3. Performed seasonally, this will keep most naturally occurring staining and discoloration from occurring.

POSSIBLE OUTCOME IF NOT DONE: the appearance of your deck will be compromised without regular, seasonal cleaning. If any organic debris is not removed it can promote the growth of mildew and pose a slip hazard. If de-icing or cleaning agents are not properly cleaned and rinsed off of a deck, it can adversely affect the appearance as the sun can ‘bake’ the chemicals into the surface causing discoloration.

#5 TASK: Deck Waterproofing

FREQUENCY (per year): As needed based on deck type and inspections

DESCRIPTION:

1. The type of deck you have will determine the amount of time and money required to sustain waterproofing performance.
2. With a wood deck, you may be required to sand and stain yearly to maintain your waterproofing and appearance.
3. With liquid coatings over concrete, re-application is required.
4. With a Duradek vinyl membrane waterproofing system, no re-application is required and the waterproofing function can perform up to 2-3 times the length of the 10-year waterproofing warranty offered by Duradek. That being said, while Duradek withstands a lot of wear and tear, if something has cut the vinyl it should be re-welded by a Duradek Trained Applicator before allowing it to leak.

POSSIBLE OUTCOME IF NOT DONE: If waterproofing is not completed as required, water can infiltrate the decking system and the building envelope, which in the case of decks over living space, can cause exponential damage and repair costs to your home.

When it comes to waterproofing decks, patios and roof decks over living space, the performance is all in the details and we highly stress the importance of using the services of a waterproofing professional who knows the many details involved in successful waterproofing.

Duradek Ultra walkable, waterproof vinyl membrane has been waterproofing decks for nearly 40 years and is available only through Duradek’s network of trained and authorized waterproofing experts.

These same waterproofing experts can provide the Durarail powder-coated aluminum railing systems to ensure your entire deck project is handled professionally and is made to last.
