Introduced back in 1987, Volclay Swelltite was the first bentonite waterproofing membrane designed for split-slab deck and plaza construction. Swelltite combines the natural waterproofing abilities of Volclay sodium bentonite with a high-strength geomembrane liner for tensile strength and puncture resistance.
Volclay Swelltite is a true advancement in waterproofing technology. Unlike other adhered membrane systems which require near-perfect installation, Swelltite’s active bentonite compound can expand to seal small installation imperfections or punctures in the membrane.
