Waterproofing really can be such an
ugly business! . . . Not anymore!

Peeling, cracking or delaminating coatings (Urethanes, Epoxies, Acrylics); leaks, rotting wood, mildew and cracked, spalling concrete - these are all common problems with the old fashioned methods of waterproofing decks and balconies.
With Duradek's pre-engineered vinyl sheet membrane system, these all too familiar defects are really a thing of the past. Duradek successfully bridges cracks that often cause the other waterproofing products to fail.

Substrates are impossible to control. They shift with everyday temperature changes. This constant movement puts enormous stress on liquid coatings. Pinholes, blisters or surface cracks often result. These allow moisture to get underneath, causing further deterioration of the membrane.

Duradek is a pre-manufactured, fabric reinforced vinyl sheet that possesses the ability to move with the subsurface, without cracking, bulging or blistering.

Both concrete and wood, over time are highly susceptible to the weather. Rain, snow, freezing, thawing, wind and sun, all take their toll. Wood decks rot, splinter, warp and crack.




The temporary decorative appeal of wood, unfortunately comes with the time and cost of constant maintenance. Concrete cracks, becomes unsightly, dangerous and expensive to repair or replace. Entire balconies can collapse or pieces can fall off, possibly endangering lives.
Leaks and costly water damage have almost always been associated with inadequately protected roofdecks, to the point where avoidance has become the only solution.
Where others fail, Duradek has the answers!
Why the Others Fail

Problems with Liquid Coatings Why It is a Problem How Duradek is Better
Usually require multiple applications. • The surface cannot be used until curing is complete.
• Alternate access must be provided.
• Proper adhesion between coats can be affected by weather, time and traffic. • Duradek is a pre-manufactured sheet, installed process, in one step - ready for immediate use. It can even be walked on during the installation meaning fewer tenant disruptions & vacancies.
Require optimal conditions for best performance. • Optimal conditions do not often exist. Temperature and humidity fluctuate hourly and daily. • Duradek can be successfully installed in almost any weather condition.
Coatings require extensive surface preparation, particularly over cracks. • Time consuming, noisy, disruptive and expensive. • Duradek is glued to almost any surface, even over cracks with minimal surface preparation.

Problems with Wood Why It is a Problem How Duradek is Better
Wood deteriorates when exposed to the elements. • Wood splits, twists, warps, splinters, rots, shrinks and requires painting or staining regularly. • Duradek requires no regular maintenance except cleaning.
Wood is slippery when wet. • Safety hazard. • Duradek can be purchased with varying degrees of non-slip surfaces.


Problems with Carpet Why It is a Problem How Duradek is Better
Carpet is not waterproof. • Carpet must be put over a waterproof surface or it accelerates the deterioration of wood or concrete. • Duradek is completely waterproof and attractive.
Carpet holds water and slows the drying. • Surfaces which are continuously wet, will rot or deteriorate more quickly. • Duradek dries quickly.
Carpet fibers deteriorate rapidly in the sun. • Requires frequent replacement. • Duradek has a long life expectancy and can in the sun. Be re-coated in the future.
• Carpet can easily be installed over Duradek.
Don't Do It the Hard Way!

"I really was led to believe that properly treated wood would be impervious to the weather. Well, I found out it wasn't, and boy was it a painful experience. Now I know that Duradek is the only guarantee of a maintenance free deck!"

Facts About Sheet Vinyl Decking

Duradek Roof & Walking Deck Membrane

All products designed for exterior use will eventually be affected by Mother Nature. PVC, man's best attempt at prolonging the life cycle of various building products, performs an admirable job in delaying the inevitable, but it will, however show some signs of degradation.

Warnings against the effects of UV (ultra violet) rays on the skin are common. After a period of years, these same rays may affect outdoor products and therefore manufacturers add UV screens and stabilizers to prolong the life of PVC (vinyl) materials. These screens are designed to resist the cracking, embrittlement and discoloration of the vinyl. The thicker the vinyl, the greater the resistance to degradation.

Appearance Versus Waterproofing
The prime function of the sheet vinyl product you purchased is to waterproof the space beneath, to protect the structure from rot, eliminate maintenance and to provide a durable long lasting, skid resistant surface. Its initial appearance will eventually deteriorate, but this does not affect its ability to provide waterproofing.

Seams
The strength of our system is in the method we use to weld the vinyl sheets together. The vinyl sheets are overlapped and heat fused. The seam is visible. Other systems that previously offered invisible seams resulted in waterproofing failures.

Scuffing
Like any other floor surface, vinyl may scuff if abused. Try to avoid dragging heavy objects over unprotected PVC. Skidding a bicycle tire, a roller blade or the edge of a running shoe across the vinyl creates friction, and the extreme heat and abrasion may possibly remove the print. Our membranes are manufactured with a solid 'base' color, which is complementary, rather than obtrusive if the print finish is removed. Normal traffic will not damage the vinyl at all. Solid color membranes are available for high traffic areas.

What Happens When the Material Ages?
If an appearance change is desired, our sheet vinyls can be painted with a specially formulated coating. The emboss texture will be preserved but any print will obviously be replaced by a solid color.

Color/Print
As a rule, the lighter the color you choose, the cooler the surface will stay and the less deterioration will occur. Darker colors will fade faster and be warmer on the feet. All vinyl tends to 'yellow' slightly. Gray's show it the most, while the 'yellowing' is hidden within earth-toned products.

Products with higher contrast in the print may show signs of fading sooner than low contrast colors. Solid colors will resist the visible effects of the UV the longest. However, high contrast in the print helps to hide blemishes in the floor surface beneath, as well as the other from everyday use. The lower the contrast in colors, the more these blemishes and the dirt will show. Solid color products are the most unforgiving. Blemishes such as plywood seams, nail head depressions or even plywood grain patterns can show up in late evening or early morning sunshine which casts a long, revealing shadow.

With our 30-plus years of experience, Duradek membranes are designed with proven blends of color, print and texture which offer the most long-lasting performance the industry can offer.

Subsurface
The better the surface, the better-finished floor we can give you. Sanded plywood or cement board will give the best-finished surface possible. As a rule, ¼" x 3/8" plywood will warp due to absorption of moisture from the atmosphere. We recommend 'over laying' with minimum ½" and preferably 5/8" plywood or 5/16" cement board for the flattest possible subsurface.

Slope
For the best product performance and customer enjoyment of their deck surface, the structure should be sloped (ideally 2%) to eliminate ponding water. Should the puddling occur, the area will require more regular cleaning due to the build up of dirt and pollutants. Ponding water will not affect the waterproofing of the vinyl but may eventually cause premature discoloration.

Penetrations
All penetrations (posts, pillars) must be sealed to prevent water entering under the vinyl. All wood posts or pillars will crack and give access for water to get into the subsurface and under the vinyl. Regular inspection and caulking is required. To completely waterproof a post, either fasten it to the fascia of the building or completely cover it with waterproof membrane and clad. When fastening metal rails or posts to the deck surface, all pilot holes should be filled with a sealant before screw is inserted.

Indoor Use
When using the vinyl indoors where the temperature change is slight, the vinyl can be butt seamed with a chemical sealer (like a kitchen floor seam). No perimeter fastening is required to control shrinkage.

Stains
Vinyl will resist most staining materials. Some do cause problems though. Exterior oil base stains, some oil stains, any tar or bitumen based product, fresh cedar, and some new wolmanized lumber may permanently stain the vinyl. Biodegradable matter such as leaves when left on the vinyl for a prolonged period may also be very difficult to clean. If any of the above should occur - try to clean it off as soon as possible so the stain doesn't have a chance to set. Refer to the Care and Cleaning Instructions on the back of the warranty card or on the website.

Warning
Do not attempt to clean stains, paint or any blemish using any bleach, acetone, turpentine, lacquer thinner, ketone, acid or multipurpose stain or print remover or you may cause removal of the print. The directions must be followed explicitly to avoid damaging the print. The cleaning solution must be dabbed, NOT rubbed, and then cleaned well with cleanser and water and then flushed with lots of clean water. Always test on an 'out of the way' place to ensure there will be no problems.
