Stamped Concrete Roof Deck Question to Expert Leads to Duradek’s Ultra Tiledek

Home Improvement expert Shell Busey has been advising BC home owners for decades on how to best maintain and improve their homes.  A question on a stamped concrete roof deck was raised this summer and was featured in the Vancouver Province Newspaper Q&A Feature ‘Ask Shell’.

Shell, who is very familiar with roof deck waterproofing solutions from a long relationship with Duradek as one of his House Smart Referral Certified products summed it up succinctly with “…always use Duradek Tiledek.”

Vancouver Province Clipping - June 2015

The Q&A article in Ask Shell “Remedying a leak on stucco”, was as follows:

Q: I have an above-ground deck half over my garage and half over the driveway. The deck has a torch down covering with stamped concrete on top.

The problem is that the deck leaks at the seam where it meets the stucco side of the house.

It is a slow leak, but I do not want to end up having damage to the stucco.

I have put caulking along the seam; it sticks well to the stucco, but not the concrete. Is there a better product I can use?

A: It sounds as though the contractor did not install a metal counter flashing when the deck was built.

A 90-degree metal counter flashing could have been cut into the stucco and placed under the concrete decking to give the best water seal.

You might still be able to have a flashing installed by a professional service trade.

In the meantime, you may want to try a polyurethane caulking, which will stick to both types of surfaces. LePage Quad-max would be a good choice.

(Note: Do not use torch down roofing membrane under concrete; always use Duradek Tiledek.)

Reliable Waterproofing of Tiledek Membranes for Roof Decks Using Pavers

It is a very common scenario that roof decks surfaced with tiles or pavers result in leaks into the home below, but fortunately it is a problem that Tiledek can remedy.

Only a couple of years after Tiledek’s  introduction, TileLetter Magazine featured an article “Waterproofing Makes All The Difference In Dual Level Decks” to show how effectively Tiledek solves leak problems under exterior tile decks.

Like all Duradek membranes, Tiledek is only installed by trained and authorized contractors who are familiar with Duradek’s superior methods of reliable waterproofing. Critical areas like where the deck meets the house are addressed with Detailed Drawings for installers to reference to ensure the building envelope is protected.

In Duradek’s installation best practices, the membrane runs up the vertical wall about 6 inches and is overlapped by the moisture barrier for 2 inches to ensure that the inside perimeter, or “seam” between deck and side of the house, cannot allow any moisture to infiltrate.

Failed Tile Decks Don’t Use Tiledek Waterproof Membrane

Tile decks are beautiful, but have a reputation as a trouble project and many contractors will shy away from them all together. There are countless stories out there about failed tiled deck projects where a home owner's beautiful new tile deck started leaking after only a short time. But you don't have to be afraid to surface your deck with tiles, even on a roof deck over living space. You only need to be sure to use a contractor that does it right, with the right products.

If you want to fulfil your dream of having a tile deck, talk to a few contractors to ensure you are getting one that knows the special considerations for tile deck projects....and if you don't hear them mention waterproofing...run away immediately!

What You Need to Know to Avoid Leaky Tile Decks with Tiledek: Part 4 – Stacking the Deck

originally published September 24, 2012

In this four-part series of detailed questions about Duradek Ultra Tiledek membranes we first familiarized you with Tiledek, discussed the alternative methods of waterproofing under exterior tile and why Tiledek is the stand-out option for doing it right the first time and guaranteeing that your deck waterproofing performs as intended.

In this fourth and final part of our Tiledek series of articles we will discuss how to first prepare your deck surface to achieve waterproofing success.

How do you build a deck to make it is ready for tile?

A major cause of failure of tile over decks and balconies is that the structure to which it is applied allows too much deflection.  Tile has little tolerance for deflection.  Cracking grout lines or tile is the result of deflection. 

Deflection (the spring or give of the deck surface) is a product of the joist spacing and thickness of the flooring materials.  The Terrazzo, Tile and Marble Association of Canada (TTMAC) specification for flooring under tile or slate is as follows:
¾ inch plywood fastened with 2” #10 Exterior wood screws @6” oc @ perimeter and 8” oc @ joists covered with ½ inch cement board secured with thinset and fasteners. (The deck must have slope built in – suggested slope ¼” per foot)

The use of a cement board overlay is required/recommended by tile associations and manufacturers.  Cement board, unlike plywood, is not affected by varying levels of moisture.

We strongly recommend that decks be built to this specification.  For the money that is being invested in the whole system, it would seem unwise to scrimp on the subsurface.  In case of a failure (cracking), the first thing anyone will look at (and blame it on) is whether the floor was strong enough and provided the necessary deflection resistance.

Concrete decks and balconies are suitable for tile application but still require proper waterproofing or roofing protection.

We recommend you follow the local best practice guidelines as laid out by the Tile Contractors Association of TTMAC or the building code. There may be regional differences in the suggested use of cement board or a second layer of plywood. As with all the details involved with a tile deck over a wood structure, you should follow the tile and thinset mortar manufacturer’s specifications.

Can tile be applied over an existing vinyl deck?

Most existing deck surfaces (PVC membrane or liquid applied finishes) are applied to 5/8 inch or ¾ inch plywood and therefore are not suitable for a tile overlay without some stiffening to reduce the deflection.  The vinyl could be removed (possibly leaving the existing vinyl up the wall behind the siding and building paper), the floor stiffened with the appropriate thickness of cement board and the Tiledek installed over top (special details will be published for this).

There is another system that can be used to stiffen the existing structure.  Schluter’s ditra mat can be installed over top of Tiledek (with thinset) and then the tile can be installed over top of Ditra.  The Ditra mat stiffens the floor system to an appropriate level to provide for residential use of tile.  We have tested this system with the Robinson Floor test and achieved a “residential” result. 

Should you protect Tiledek until the tile is applied?

Like all products installed on a construction site, Tiledek is susceptible to damage from other trades, scaffolding, paint, stucco, materials or tools being dropped from above or other abuse.  Although Tiledek is very tough (as we know from Duradek) and can take a lot of abuse, it is always wise to protect it especially in heavy traffic areas or areas which are most likely to be damaged.  Covering it with a protection board (plywood, recovery board etc) will save time and effort cleaning the Tiledek to prepare it for accepting the tile overlay.  A layer of polyethylene under the panels will protect the membrane from liquids (paints etc). Another method of protection would be to trowel apply directly to the Tiledek a thin coating of the same thinset material that will be used to apply the tile or stone overlay. 

How do you clean Tiledek if necessary?

If Tiledek has been left exposed to traffic and construction debris and needs to be cleaned, it can be cleaned easily and effectively.  Pressure washing with a light (1500 psi) spray with the nozzle no closer than 6 inches from the surface will work well.  The surface can also be washed and lightly scrubbed with a bristle broom and hosed off.

Does the surface need to be sloped?

Yes!  Sound roofing/waterproofing practice needs to be employed even when tile is applied over top.  We operate on the expectation of water getting through the tile installation.  Our membrane will be applied to a surface sloped towards drains, scuppers or an outside edge which allows the water to escape. 

Moisture will still run downhill, even under tile applications.  This can happen without negatively affecting the bond of the thinset mortar to the tile or the membrane.

We recommend the seams of the Tiledek run parallel to the slope to avoid any water puddling up behind the bump.

Can a flat waterproof surface be re-sloped with a thickset application technique?

While it is possible to provide a slope with the thickset mortar, there are other problems to consider.  If the waterproof membrane is flat or allows water to puddle on it, providing a sloped mortar bed will NOT remove all the water from the deck.  Although most of the moisture will drain off the top surface, water WILL enter under the tile through cracks in the grout joints, cracks in the tile or on perimeters.  The water that enters will follow the slope of the waterproofing membrane.  If it puddles before the thickset mortar goes on, it will still puddle after the tile job is completed.  The water will then just sit in a puddle and stagnate, potentially causing mould and an unpleasant odor to occur.
If you want to take a belly or depression out of the deck surface, it must be done prior to the Tiledek being installed. Since water will not penetrate Tiledek, if the depression has been eliminated any water reaching it will be shed away.

Water testing before the Overlay is Applied

We recommend a water test be done after the Tiledek is installed and prior to the overlay being applied.

Conclusion

If you have read all four parts of this series of articles on Tiledek and waterproofing methods for exterior tile projects, you are well equipped to ask all of the right questions to all parties involved in the construction of a reliable and long-lasting outdoor tile deck.

At Duradek we believe that your deck should be a source of pleasure, not stress, and we encourage all home owners and builders to ensure they do it right the first time….do it with Duradek Ultra Tiledek.

What You Need to Know to Avoid Leaky Tile Decks with Tiledek: Part 3- Installation

originally published on September 17, 2012

In part one of this four-part series of detailed questions about Duradek Ultra Tiledek membranes we first familiarized you with Tiledek and the necessity of having a reliable waterproof system under your outdoor tile decks and the typical methods of installing outdoor tile.

In part two, we discussed the alternative methods of waterproofing under exterior tile, and why Tiledek is the superior choice.

In this third part of this series we will expand on why Tiledek is the stand-out option for doing it right the first time and guaranteeing that your deck waterproofing performs as intended.

How is Tiledek installed?

Tiledek is installed using almost identical techniques to the installation of Duradek. We use the same adhesives, heat welded seams, and waterproofing details. There are a few finish details that differ due to the tile that will be installed after we are done. Here are the areas that require different techniques:

Tile Deck with Custom Flashing Details

Outside perimeters: As with regular Duradek, there are many ways to finish the outside perimeter of a tile deck. As water proofers, we need to establish what “look” the owner wants to be able to advise them properly. You should consult with both the builder and the tile setter to discuss the perimeter finish details. Depending upon their desired finish, we can alter our detailing. This is an area where we can offer our customers excellent service and help them make good waterproofing decisions while taking all the future steps they will go through into consideration. Our attention to these details contributes to the overall success of the job.

Drains: Should drains be necessary, we cannot use our regular WDD1 system. We recommend a special cast drain with a square top to make it easier and more attractive for the tile applicator to finish to.

Rail attachments: We strongly recommend attaching rails to the fascia instead of the surface of the deck. DO NOT INSTALL RAILS OVER TOP OF TILE AS IT WILL CAUSE THE OVERLAY TO CRACK. We have special details for surface mounted rails if there is no other alternative.

Proper installation required running the membrane
up the wall and "cut-in" to the brick.

Inside perimeter: If the owner wants the tile to return up the wall as part of their finished look, appropriate flashings are needed. If not, then consideration must be given to the visibility of the part of the membrane that returns up the wall and hiding the gap that must be left on the inside of the tile application.

Surface preparation: Apart from a thorough inspection for a properly fastened substrate, there is little prep work necessary. A light sanding of the joints of the cement board or a scraping of the entire surface to take care of any bumps will suffice. No filling is required.

Who installs Tiledek?

Tiledek can only be installed by a qualified Duradek applicator who has gone through our training program and who works for an authorized Duradek applicating contractor. That is how we can give our customers superior protection in making sure it is done right.

Do we recommend tile installations in cold climates?

We do not profess to be tile experts. Manufacturers of the tile and the installation accessories must answer this question. We are waterproofing professionals. We can protect the structure from water damage no matter how hot or cold or wet the climate is. And we can provide a membrane to which thinset mortars will tenaciously adhere. We cannot (and do not) guarantee tiles will not erupt as a result of freezing temperatures but we can (and do) guarantee the water that gets under the tile will not get into the building.

There are currently countless decks and balconies in cold climates being overlaid with tile. People like the look and are going to continue to use it regardless of if it is a good idea. Our part is to make sure they don’t suffer water damage.

Is Tiledek an Anti Fracture Membrane?

Example of Tiledek Assembly Build Up

Tiledek will add a very small amount of fracture resistance to the system but should not be purchased as an anti-fracture membrane. Because it is glued to the subsurface, movement beneath the Tiledek membrane may transfer through into the tile.

Will an anti-fracture membrane eliminate the need for a control joint?

It is a frequent misconception that anti-fracture membranes allow you to eliminate expansion joints - they do not. There always must be soft joints in the tile work to allow for expansion and contraction. Guidelines for expansion joint placement are given in the Tile Council of North America Handbook. The exact placement of expansion joints is a function of many items including exposure to sunlight and the range of high to low temperature, moisture, aging of the concrete (where relevant), structural movement, expected loading, and other design criteria. It is a common recommendation that there be expansion joints every 8 - 10 feet in any direction. The manufacturer's recommendations should also be consulted and followed.

On ¾ inch plywood covered with Tiledek plus a layer of Schluter’s Ditra Mat, we achieved a residential rating.

What You Need to Know to Avoid Leaky Tile Decks with Tiledek Waterproof Membrane: Part 2 – The Alternatives

originally published on September 9, 2012

In part one of this four-part series of detailed questions about Duradek Ultra Tiledek membranes we explained what Tiledek is, why waterproofing is essential in outdoor tile applications, specific details on evaluations and testing results on Tiledek as a roofing membrane, and the typical methods of installing outdoor tile.

This week, we will discuss the alternative methods of waterproofing under exterior tile, and why Tiledek is the superior choice.

What does Tiledek compete with?

The answer to this question depends upon the deck being over living quarters or not.  Obviously if it is over living quarters, then the membrane must be a roofing membrane and more importantly, it must be installed with roofing principles in mind.  Should the deck not be over living quarters, there might be no building code requirement that the membrane is a roofing product but the installation details should be no less stringent considering the consequences of leaks.  Water intrusion can cause very expensive damage to the structure and we believe all waterproofing jobs demand the attention of a professional.

For the purposes of this discussion, we will separately deal with roofing and non-roofing applications.

For Roofing purposes:

Torch applied or self-adhering modified bitumen roofing materials:  
Modified Bitumen (MB) is asphalt that has had modifiers added to it to give it plastic or rubber-like properties. The most common types of modifiers being used are APP (Atactic Polypropylene) and SBS (Styrene Butadiene Styrene).

Methods of applying modified bitumen.

Rolls of modified bitumen membrane come in widths of 36" (0.9 m) to approximately 39" (1 m) and cover an area of approximately 100 square feet to 112 square feet.

Modified Bitumen roof systems consist of one, two, or three ply systems. (Base sheets with no cosmetic finish and cap sheets) The cap sheet membranes may be applied using a torch (the back of the sheet has extra asphalt on it which, when heated, bonds to the substrate) or be self adhered (removing a release paper on the back exposes a sticky surface which adheres to the substrate).

Modified bitumen
asphalt Effluence

To the best of our knowledge, none of the manufacturers of Modified Bitumen materials supports tile installations over top of the roof membrane and therefore provide no promise that it works and certainly no guarantee.  In addition, the asphalt in these products is not compatible with the mortar in the thinset or the grout lines and may bleed through causing a discoloration.

More importantly, when the MB softens as it heats up it can be compressed and may allow the tile or the grouting to crack from the movement from traffic on top.  Any product that is designed to have tile installed overtop will have test results from the Robinson test (ASTM C627) to verify it is capable of supporting weight of people and equipment.

See Tiledek Techtalk #106 – 10 Reasons Not to Use Modified Bitumen

Roof membrane plus a thickbed mortar system:

Adhering Duradek Ultra Tiledek

The traditional method of providing roofing protection under tile would be to install a suitable roofing product like PVC, epdm, tpo, modified bitumen or liquid applied urethanes, etc. with a thickbed mortar system on top to which the tile is attached.  (It is important to know whether or not the manufacturer supports the use of their product in an application like this.)  The tile may be “uncoupled” from the mortar bed or the mortar bed uncoupled from the roofing membrane or both.  There may be a drainage layer above the roofing membrane to allow any moisture that gets in to escape along the drainage plane.

This system is very expensive and quite thick (at least 1-½ inches above the membrane).  There may be as many as 7 or 8 layers involved in the system.   For examples of what they may look like, go to www.schluter.com and see their balcony details.

Either Tiledek or Duradek Ultra would make for suitable roofing membranes under this type of system.  Duradek does warranty its product for this application.

Note:  In Canada, on wood framed structures (part 9 of the National Building Code) all decks and balconies are required to use an approved roofing membrane.  

Non-roofing applications
(referred to as “waterproofing” membranes)

The first thing you will notice when researching the products that are available for waterproofing decks and balconies to which tile will be applied is the lack of the word “roofing”.  Most manufacturers of these systems want nothing to do with the details, the headaches and the liabilities involved in roofing.  You will notice details that we would not even consider using in a non-roofing application (such as finishing a membrane on the flat horizontal surface without turning it over the edge and then caulking the leading edge).  Most of the details you see are for concrete decks and balconies, not for the wood frame construction, which we are most likely to be dealing with.

 

Why is Tiledek superior to the alternatives?

As you can tell from the extensive list of other products that are available for “waterproof” applications under tile, there are very few who claim to be roofing products.  Most of the details on the websites of the products are meant for waterproofing concrete balconies and ARE NOT an “apples to apples” comparison to the kind of waterproofing we do with our materials. 

Cap welding the membrane as step 3 of
the triple heat-welded system.

We treat each and every deck as if it was a roof and we detail accordingly.  It doesn’t take much of a study to see how superior our details are.  But the most significant reason why Tiledek is superior to all the other alternatives is the network of professional applicators that install the product.  Duradek (and therefore Tiledek) is only sold through a network of businesses that have been trained.  There is no other way to get the product installed.  That means huge protection for the building owner.  THE MOST IMPORTANT PART OF THE PROCESS IS THE CONTRACTOR WHO CARES ABOUT DOING IT RIGHT.

Our primary responsibility is to protect the building from water finding its way in.  Regardless of the success or possible failure of the tile overlay, we can GUARANTEE our customers that their home will be protected from water damage.

As far as the product is concerned, you can clearly see the superiority of a 60-mil layer of the same PVC we use for walking roof decks to provide the waterproofing protection needed.  Many of the systems we’ve identified are very thin layers of liquid (20 mils).  Some of the sheet systems are only 20 mils or less and even the thickest are only 40 mils.  The seams of the sheet materials are done with liquid seam sealers and we know how ineffective that has been over the years.  Some of the thicker “solutions” are very soft rubber that could allow too much movement of the tile and may promote cracks in the grout or the tile.  Clearly, Tiledek is to be considered as the superior system of waterproofing for exterior decks or balconies overlaid with tile.

What You Need to Know to Avoid Leaky Tile Decks with Tiledek Membranes - Part 1

originally published September 3, 2012

Part 1 – Getting Familiar with Tiledek

Leaky tile decks are a source of frustration for many builders and homeowners throughout North America, particularly when the tile deck is above living space. However, the methods that have been used in the past without much success are no longer the only options. Duradek Ultra Tiledek was manufactured specifically to provide waterproofing peace of mind underneath exterior tile roof decks. It is the only roofing membrane specifically produced for waterproofing under outdoor tile AND that comes with a 10-year warranty that guarantees waterproof protection.

This month we will be publishing a 4-part series in a basic Q & A format every Wednesday to help you get acquainted with the specifics of Tiledek and waterproofing under exterior tile.

In part one, we will familiarize you with Tiledek and why it is the essential waterproofing component for outdoor tile projects.

What is Tiledek

Duradek Ultra Tiledek is a 60 mil thick, PVC roofing membrane similar to Duradek “Ultra”. It is designed to have outdoor porcelain tile or slate installed over top of it with a thinset mortar bond coat. Lightweight concrete or cementitious finishes can also be installed over it. From here on we will just refer to the overlay products as ‘tile’.

A fabric has been laminated to the topside of the roofing membrane to provide for a strong physical “grab” by the thinset mortar.  Tiledek comes in rolls 6 feet wide and 75 feet long.  Tiledek is only available as a “professionally installed waterproofing system” through the network of trained Duradek applicating contractors all over North America.

Is an outdoor tile application waterproof by itself?

Absolutely not!  It is absolutely certain that water will get under the tile.  That is precisely why there are so many problems with outdoor tile decks.  People THINK and are even misled to believe that a tile installation is waterproof and therefore they don’t pay too much attention to the proper waterproof treatment underneath. The failures are often waterproofing failures where leaks that have been happening undiscovered for years eventually cause rot requiring major renovation work.  Not only does the structure need replacement work, the tile application must also be torn up to get at it.

The water will most likely enter through cracked grout joints or on the perimeters.  If the tile cracks, water will enter.  If the deck is in a cold climate, the moisture freezes, expands and may cause tiles to erupt.

A failure in the tile installation doesn’t mean the waterproofing system has failed.  If the membrane is intact and performing its function of keeping the water out, replacing a cracked or erupted tile or a cracked grout joint is relatively easy and inexpensive.

What are Tiledek’s credentials?

Tiledek is a variation of Duradek Ultra, the first PVC walking roof deck material on the market.  Duradek Ultra has been installed for over 35 years and has proven itself in all climatic regions of North America.

Quality Auditing Institute Ltd.(QAI), an independent testing, inspection and certification agency, evaluated the Tiledek membrane (Evaluation Report T731-4), and based on this evaluation determined that Tiledek is considered compliant to the following criteria:

• ICC-ES:  Tiledek meets the requirements of ICC-ES AC39 "Acceptance Criteria for Walking Decks" and ICC-ES AC75 "Acceptance Criteria for Membrane Roof Covering Systems" as a roofing membrane when installed in accordance with the IBC 2009 or IRC 2009 and the manufacturers installation instructions.
• CAN/CGSB 37.54: Tiledek meets the requirements for conformance to the materials standard of CAN/CGSB-37.54-95 "Polyvinyl Chloride Roofing and Waterproofing Membrane" classified as a Type 3, Class A membrane.
• Class “A” Fire Rating: Tiledek is considered to have a Class “A” rating when tested to ULC-S107 "Methods of Fire Tests of Roof Coverings" and ASTM E-108 “Standard Test Methods for Fire Tests of Roof Coverings" (when installed on and covered by non-combustible building components).
• ASTM C627: Tiledek meets the requirements of the standard test method for evaluating ceramic floor installation using the Robinson-type floor tester. Test Report #UFT 2008-008, #UFT 2008-009, #UFT 2008-010.
  Test conducted by Terrazzo, Tile & Marble Association of Canada (TTMAC). 
• ANSI A118.10: Tiledek meets the requirements of the ANSI specification for load bearing, bonded, waterproof membranes for thin-set ceramic tile and dimension stone installations. Test Report #TCNA-428-10.
  Test conducted by the Tile Council of North America (TCNA).

Robinson Type Universal Floor Tester

Tiledek Techtalk #108 provides a summary of Tiledek testing and approvals in pdf format.

What is the warranty with Tiledek?

Tiledek is covered with the same waterproof warranty as Duradek Ultra – 10 years.  See the sample warranty on the Duradek website for the specific terms and conditions.

How is tile usually installed on decks and balconies?

There are two distinct methods of installing tile in waterproof applications:  thickset (using a 1-½ inch “dry mud bed”) and thinset (using a ¼ inch acrylic modified mortar).

Thickset Mortar

Thickset: Thickbed installations are based on the traditional method of packing a mortar bed over a surface before installing the tile. The tile is adhered to the mortar bed either while the mortar bed is green (just beginning to dry) or after the mortar bed has cured. The mortar bed may be reinforced with wire and either set over a cleavage membrane (that allows the mortar bed to "float" free of the substrate) or bonded to the substrate - hence the use of the terms "floating mortar bed" or "bonded mortar bed". For wall applications, metal lath is mechanically anchored to the substrate and the mortar locks into the metal lath as it cures. The terms thick-bed installation, mortar bed installation, and thickset installation are synonymous.

The thickset method is more likely to be used where the tile is thick and irregular in order to achieve a flat walking surface.

Thinset Mortar

Thinset: Thinset mortar is a blend of cement, very finely graded sand, and a water retention compound that allows the cement to properly hydrate. Tile set by the thinset method is adhered to the substrate with a thin layer of "thinset" mortar. This type of cement is designed to adhere well in a thin layer - typically not greater than 3/16th thick. For example, a 3/8" notch trowel will produce a 3/16th inch thick coating after the tiles are pressed in to the cement. While very minor adjustments in height can be made, this method is not appropriate for adjusting the level or flatness of a surface - rather the tile will follow the plane of the substrate. Only “Gauged” tiles (with similar thickness) should be used in thinset mortar applications.

Medium-set: Medium-set mortars can be used to adjust for slightly larger variations in the substrate than can be accommodated with thinset mortar. They are also used with large, heavy, thick or “ungauged” (varying thickness) tiles, where a thicker setting bed and a coarser aggregate may be required to achieve a flat installation and to support the weight of the tile while the cement is curing.

HGTV’s Income Property Called on Duradek for a Waterproofing Solution

Popular HGTV home renovation show 'Income Property' urgently needed a waterproofing solution and they knew the waterproofing professionals of Duradek could help them solve it.

Host, Scott McGillivray and his team were working on a complete basement renovation to create a rentable income suite so the new owners could afford their new home, and with a new baby coming there was no time to waste and no money to spare.

Everybody was excited about the plans and even the electrical upgrades and asbestos removal wasn’t cause for concern. It was when they were removing the ceiling panels that enthusiasm was dampened. And dampened was exactly what had happened to the framework of the home.


"I have to tell you, I've never seen anything like this." - Scott McGillivray

Initially, the source of the moisture was unknown, but at some point a corner-cutting contractor had cut a tubing pipe in half to act as a channel to route accumulated water from its unknown source through the ceiling and down the wall to a drainage pipe. You don’t have to be a building expert to know that method is not an ideal water management solution, but the real concern now was that until the source of the water infiltration was found, any and all efforts they invested into the basement renovation would be wasted. The affordability of the house without the income suite was not realistic and having taken on a huge mortgage, the owners were in a very vulnerable position.

Scott McGillivray knew this critical element must be solved before proceeding. Through testing by applying water to the suspected points of entry, Scott determined that the water was entering the home through the flagstone back porch entryway that was situated over the suite. This is an unfortunately common problem when builders who are not waterproofing specialists mistakenly assume the stone and mortar will be enough to stop water infiltration, but over time water will always make its way through.

One of Scott’s team members recalled using Duradek on a previous project and knew it was a reliable method of waterproofing, so they decided to try using a Duradek vinyl membrane and then laying the flagstone pavers on top of it. When the show contacted Duradek to help supply this important building material for episode 8, Sales Manager Kevin MacMillan was able to offer something even better suited for their project - Duradek Ultra Tiledek.


Rolling out the Tiledek membrane.

Tiledek was the perfect solution for this problem and a better option than laying the flagstone pavers over top of the original walkable Duradek vinyl membrane. Tiledek is made with the same quality PVC and is applied with the same professional waterproofing details as the original Duradek membrane. It even comes with a 10 year waterproofing warranty like the original Duradek and Tiledek has been tested and approved as a roofing membrane. The feature that made Tiledek the superior solution for this project is that Tiledek is manufactured with a fabric-embedded surface intended to accept a thin set mortar to adhere a final walking surface like tile or the flagstone pavers. So on this project, Tiledek was the best solution for providing a 100% waterproof system.

The Duradek Ultra Tiledek was installed by HTR Duradek in Ontario; one of Duradek’s leading authorized installers. All Duradek waterproofing systems are available only through authorized installers that have been trained in the intricate details involved in the specialty trade of deck waterproofing.

Only after the membrane was securely installed with all of the proper attention to the perimeter and drainage details could the stone layers come in to finish the job. Fortunately, with Tiledek membranes, once it is installed there is no drying or curing time required and the stone layers could start their part of the project immediately with no time delays to keep the project on track.


With the Tiledek waterproofing installation complete, the
stone layers can get to work right away to finish the job.

With the water infiltration resolved, the rest of the renovation was completed and the owners could proceed with finding a tenant for their beautiful new suite to help them afford the home where they can raise their family.


The finished porch...all water-tight!

Watch HGTV to See How the Professionals Rely on Duradek Ultra Tiledek

Tomorrow, Thursday, November 7th, 2013, HGTV's lifestyle series 'Income Property' airs episode 'Nick and Karen' in which Duradek Ultra Tiledek is used to solve a difficult waterproofing problem. Airing on November 7th on HGTV Canada and Tuesday November 12th on HGTV U.S. (check your local listings) Income Property is all about bringing in revenue from your real estate. Protecting the structure of the home and your investment into it while avoiding costly repairs is a very important part of that.

Many HGTV programs show what can happen in a home where years of DIY projects or even the use of unqualified contractors can turn a simple project into a catastrophic rebuild, but perhaps no home renovation or maintenance project is as critical as waterproofing.

Once water has invaded a home, wood rot, mold and a number of undesirable consequences can turn even a mostly well built home into an ongoing maintenance project. That is why it is so important to use qualified tradesmen for the specialty skill of deck waterproofing. Not only is it important to have a structurally sound and waterproofed deck, but there is a direct relation to the water-tightness of the building envelope that can affect other areas of the home.

This is particularly important when a deck is situated over living space....and that is why even the professional builders call on Duradek for waterproofing decks over living space.

See how HGTV's Builder Boss used Tiledek in a unique roof deck application over a subterranean room in our article 'The Builder Boss Relies on Duradek Ultra Tiledek' or how Mike Holmes made it right with Duradek on episode 7081 Rocky Reno.



Stone, tile and pavers still require a method of waterproofing underneath.

On Income Property's 'Nick and Karen", Duradek Ultra Tiledek is used to waterproof a small back porch.

Tiledek is the ideal membrane waterproofing for use under outdoor tile. Many people are familiar with the original Duradek membranes that provide the waterproofing and walking surface in one, but Tiledek provides secure roof grade waterproof protection with a PVC membrane that was developed with a textured surface to best adhere thin set tiles. Used in conjunction with other elements of your outdoor tile assembly, Tiledek is able to provide relief from leaky tile decks where other systems fail.

In this particular project the overall square footage of the porch does not make it seem like a significant factor, but the fact that it is situated over living space which is intended to be the income generating part of the property makes it one of the most critical details in this project overall.

Income Property host, Scott McGillvary's hands on approach to renovation and real estate has enabled him to build his own real estate empire with dozens of properties and hundreds of tenants. Scott takes his knowledge and experience to help cash-strapped homeowners and teaches them how to generate income from their existing residence. A big part of that is starting with the right products for home renovations.

Leaky Deck Frustration Turned Around in Utah

It’s a common story. A homeowner who has the desirable feature of a roof deck or multi-level decks on their home wants to make the space the ideal entertainment area. Some homeowners that have decks that are situated over living space have experienced reoccurring frustration with water intrusion, and perhaps even more frustration with their contractors that were unable to provide reliable waterproofing.

Sometimes, these same contractors will charge homeowners each time they re-apply the same ineffective waterproofing product. Here’s where the biggest frustration lies. Most homeowners are willing to pay to get the job done right, but when they repeatedly invest in ineffective solutions it is very disheartening.

TileLetter Magazine spoke with a home-owner in Utah that experienced this common story and sought the services of a new contractor (see full story on page 36). While the previous contractor had used a simple roll-on liquid coating and fibreglass mesh system, the new contractor had a different arsenal of weapons to fight water invasion. The homeowner noticed a Tiledek binder that the contractor had brought along with him and inquired about how suitable a tiled surface might be for their deck. The contractor had discovered the Tiledek system of waterproofing at a trade show, had researched the product and was confident it was the best option for tile deck projects, particularly over living space.



MBL Contracting applied the Tiledek membrane with
a proven assembly for waterproof protection under tile.

Tile is often selected as the surface finish for its beauty and relative low-maintenance appeal. While tile decks convey a simple elegance, there is nothing charming about a leaky tile deck that allows water to slowly but relentlessly invade your home. Although hesitant after the last experience, the homeowner decided to proceed with the tile option for their deck when they learned that Tiledek was approved as a roofing membrane and came with a 10-year waterproofing warranty.

Since Tiledek (as well as all Duradek waterproofing membranes) is installed only by applicators that have been trained for correct application techniques, Duradek authorized installer MBL Contracting was hired to do the waterproofing and tile setting.

If you are considering a tile deck or have a roof deck on your home, this Article from TileLetter Magazine “Waterproofing Makes All the Difference in Dual Level Deck” is a quick read and a great example to learn from before taking on your tile deck project.

A tiled roof deck makes an ideal entertainment area.
