A Non-Gypsum Waterproof Drywall Replacement System for Flood-Prone Areas
The EnduraFlood ENDU-BOARD 48″ × 33″ panel is a 100% waterproof, removable, non-gypsum wall board engineered to replace traditional 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 wall system, this panel provides durable, removable, 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.
 
Key Features
100% Waterproof Construction – Built for direct water exposure
Non-Gypsum, Inorganic Material – Will not rot, swell, or degrade
Mold-Resistant Composition – Inhibits microbial growth
Durable & Lightweight – Strong yet easier to handle than traditional materials
Designed for the EnduraFlood System – Integrates with trims and components for a complete flood-ready wall assembly
 
Built for Flood Exposure & Post-Flood Recovery
ENDU-BOARD is engineered for resilience. In flood-prone environments where traditional drywall must be removed and replaced after water intrusion, this waterproof panel system supports faster restoration and reduced long-term damage.
It is not simply moisture-resistant “green board” — it is a true waterproof drywall alternative designed to withstand repeated water exposure.
 
Ideal Applications
Residential flood protection upgrades
FEMA compliance improvements
Hurricane and coastal rebuilding
Basement finishing in high-water-table regions
