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

Duradek Roof & Walking Deck Vinyl Membrane
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!"
