Why DecTec?

Membrane Concepts exclusively installs and supports DecTec technologies. By utilizing the best materials available on the market today, we are able to deliver a deck membrane system that lasts for years with little maintenance.

DecTec products are both waterproof and fire-resistant.

DecTec’s membrane is adhered to the deck substrate by either a water-based or solvent-based adhesive. The membrane roll stock, once adhered to the substrate, is heat-welded together to create a completely waterproof seam, stronger than the membrane itself.

DecTec Guardian is the only deck membrane in the industry to achieve a Class C fire rating when directly adhered to 5/8” T&G plywood. Our unique fiberglass reinforcement combined with our exclusive spread coat process provides our ability to meet and exceed the vigorous requirements of Class C.

DecTec brand membrane self-extinguishes once the source of the flame is removed. This is due to the polymers natural ability. Lesser quality deck membranes incorporate inexpensive fillers as a means to control cost, and those that continue to burn.

When determining a membrane for your home, or project, remember it’s the polymer, not the filler that keeps out water and provides the long term performance you demand.
