A Non-Gypsum Waterproof Drywall Replacement System for Flood-Prone Areas
The EnduraFlood ENDU-BOARD 48″ × 21″ panel is a 100% waterproof, removable, non-gypsum wall board engineered to replace traditional gypsum drywall in areas exposed to flooding, storm surge, and high water conditions. Unlike conventional gypsum drywall that deteriorates when wet, ENDU-BOARD is made from an inorganic polymer composite that will not absorb water, swell, crumble, or support mold growth.
 
Designed specifically as part of the EnduraFlood waterproof drywall system, this panel provides removable, durable, flood-resistant wall protection while maintaining a clean, drywall-like appearance.
 
Why Choose ENDU-BOARD Instead of Traditional Gypsum Drywall?
Standard gypsum drywall is highly vulnerable to water damage. Even minimal exposure can result in swelling, structural weakening, and costly tear-outs. ENDU-BOARD offers a true waterproof drywall replacement system designed for:
Basements
Coastal homes
Flood zones
Hurricane-prone regions
Post-disaster rebuilding projects
Because it contains no gypsum, ENDU-BOARD will not deteriorate after direct water exposure. After a flood event, panels can remain intact, helping simplify drying and recovery.
