A Non-Gypsum Waterproof Drywall Replacement System for Flood-Prone Areas
The EnduraFlood HORI-BOR/O is a waterproof baseboard outside corner trim engineered for use with the EnduraFlood flood-resistant wall system in areas exposed to flooding, storm surge, and high water conditions. Unlike traditional baseboard corner trim that can absorb water, swell, and promote mold growth, HORI-BOR/O is made from a durable, waterproof inorganic polymer composite that will not absorb water, swell, deteriorate, or support mold growth.
 
Designed specifically as part of the EnduraFlood waterproof drywall system, HORI-BOR/O finishes UNI-BASE outside corners, providing a clean, decorative transition from ENDU-BOARD wall panels to the floor with a quarter-round top profile reminiscent of conventional baseboard trim.
 
Why Choose HORI-BOR/O Instead of Traditional Baseboard Corner Trim?
Standard baseboard corner trim is vulnerable to water damage. Even minimal exposure can result in swelling, warping, and conditions that promote mold growth behind the wall. HORI-BOR/O offers a true waterproof baseboard corner trim solution designed for:
Basements
Coastal homes
Flood zones
Hurricane-prone regions
Post-disaster rebuilding projects
Because it is made from a waterproof inorganic polymer composite, HORI-BOR/O will not deteriorate after direct water exposure. After a flood event, the trim remains intact and supports easy panel removal for drying and inspection.
