Delta MS can be used as an underslab vapor retarder layer for concrete slabs on or below grade in residential and commercial environments. Delta MS Underslab acts as a tough membrane impermeable to water and vapor that is placed on the earth or granular base prior to placing the concrete. It will not tear or rupture, allowing normal concrete placement. Cosella-Dorken Products Inc. 888-433-5824. www.cosella-dorken.com
