PROFLEX™ PRODUCTS, INC. manufactures state-of the art moisture vapor control membranes.

PROFLEX™ membranes help prevent moisture vapor drive (that is, moisture from below) from transmitting through to the finished floor. The waterproofing feature helps prevent water intrusion (that is, water from above) from penetrating to the substrate below. Waterproofing membranes are part of the entire waterproofing system and building envelope protection.

RST (Rubber Seam Tape) is a 28 mil tape for seaming PROFLEX™ membranes to create a seamless, monolithic sheet over the entire floor. RST sold in rolls 4” wide and 75” long.
