VaporStop is a high performance under slab vapor barrier/retarder designed to retard moisture migration through concrete slabs-on-grade. It's a time-proven and cost effective way of controlling moisture. Constructed from high-strength polyethylene, VaporStop is designed to help insure quality construction and energy savings in building projects.
VaporStop is available in 10 mil (VaporStop 10) and 15 mil (VaporStop 15) thickness.
VaporStop Tape is designed to bond specifically to vapor barier/retarder, making it ideal for sealing VaporStop seams and penetrations. Available in 9 mil thickness, 2" or 4" width by 60 yards long rolls.
