Vapor barrier drainage matting underlayment has water channels created by molding high density polyethylene (HDPE) into sheets featuring aligned dimples. The stud-shaped dimples create space between the vapor barrier and the ground, allowing water to flow quickly and harmlessly away while protecting the crawl space vapor barrier.
• 100% recycled HDPE content used for the base material, environmentally safe and non-toxic
• Linear aligned dimples for a clear open drainage path for bulk water transport
• Membrane can be installed in any climate – is not weather dependent
• Compression strength of sheet meets IRC requirements for lateral earth pressures to 16 ft – 7590psf
