A Non-Gypsum Waterproof Drywall Replacement System for Flood-Prone Areas
The EnduraFlood ENDU-KOARD 48″ × 33″ 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.  (ENDU-KOARD is a style of ENDU-BOARD with decorative 1/4"-wide grooves for a wainscoting-style look)
 
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 Drywall?
Standard 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.
