WhiteCap Dimple Drainage Matting is described as the installer's "Best Friend." Use it once, and you won't want to do an installation without it. Turns the entire crawlspace floor into one giant kneepad that protects the vapor barrier liner from puncture and wear. At 25mil thickness, the dimpled drainage matting combines with 20mil Whitecap reinforced liner for a total of 45 mils of protection. WhiteCap drainage matting improves water movement due to the dimpled design and may enhance the effectiveness of a radon system.
The White Cap Dimple Drainage Matting rolls are made of high-density polyethylene (HDPE) that offers strong resistance to hydrostatic pressure and excellent drainage. The dimples are aligned along a vertical and horizontal axis to channel water from grade to the footer drainage system rapidly. The stud-shaped dimples provide an air chamber between the roll and its mating surface. White Cap Drainage Matting is considered a GREEN product due to the recycled content used to produce the sheets.
