We are pleased to introduce our latest crawlspace encapsulation product: GREATSPACE Drainage Matting. This product can easily be set up beneath the GREATSPACE vapor barrier, the air gap dimple board provides the crawlspace with extra layers of:

  • Drainage
  • Durability


The White Cap Drainage Matting rolls are made of a high-density polyethylene (HDPE) that offers a strong resistance to hydrostatic pressure and excellent drainage. The dimples are aligned along a vertical and horizontal axis to rapidly channel water from grade to the footer drainage system. The stud shaped dimples provide an air chamber between the roll and its mating surface. White Cap Drainage Matting is considered GREEN products due to the recycled content used to produce the sheets. Meets/exceeds ICC-AC114: Acceptance Criteria for Rigid, Polyethylene, Below-grade, Dampproofing and Wall Waterproofing Material.
