Composite bentonite waterproofing system
Exceptional waterproofing performance
Combining the active waterproofing benefits of sodium bentonite with the strength and durability of a thick geomembrane liner. Unlike other membrane systems that require precise installation, SWELLTITE’s reactive bentonite compound can expand to seal small punctures in the membrane. SWELLTITE works by forming a continuous membrane upon hydration with water. When confined under pressure, the swell is controlled, forming a dense, positive seal against the concrete. Proven quality and ease of installation have made SWELLTITE a market leader in the waterproofing industry. More than 50 million square feet of SWELLTITE have been installed worldwide on projects such as split-slab plaza decks, backfilled foundation walls, and cut-and-cover tunnels.
