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 or vapor. 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 New Zealand waterproofing industry. For more than 20 years SWELLTITE has been installed in New Zealand on projects such as split-slab plaza decks, backfilled foundation walls, and cut-and-cover tunnels.
APPLICATIONS: Swelltite is designed for waterproofing below-grade vertical and horizontal structural surfaces, as well as, above grade split-slab construction used with plaza areas, parking garages and sports stadiums. Swelltite is excellent for:
