3.3 ft x 65.6 ft Henry Blueskin PreSeal 320 Pre-Applied Waterproofing Membrane

Henry ® Blueskin PreSeal™ 320 is a pre-applied, fully and permanently bonded composite sheet membrane system for waterproof construction. The membrane contains an adhesive and provides for mechanical attachment into wet concrete to form a permanent barrier seal. Blueskin PreSeal 320 consists of a polypropylene (PP) membrane laminated to a chemically enhanced non-woven geotextile fleece with a dimpled surface. Blueskin PreSeal 320 is pre-applied prior to rebar installation and concrete placement.
