GCP Applied Technologies, formerly Grace, has introduced Adcor® SAS 500S, a conformable, swellable polymer/butyl rubber waterstop strip for waterproofing at the joint. This product expands in contact with water offering an effective and longer lasting seal. Using a peel-and-stick application, Adcor SAS 500S eliminates the need for adhesives, nailing or fixing methods. It allows quick installation in any construction assembly, working well over nail and mesh fixing, and bonding to concrete, metal, or PVC substrates.
Adcor SAS 500S has been specifically developed to provide a faster waterstop application and higher performance than conventional bentonite or other swellable rubber waterstops.
