Mar-flex Waterproofing Products

Dampproofing and Foundation Coating

Mar-flex Dampproofing is a heavy-bodied cut-back asphalt emulsion protective coating used when dampproofing is required. It forms a smooth, tough, almost rubber-like film when dry. Mar-flex Dampproofing has a moderately good resistance to temperature changes, is flexible at low temperatures, has excellent weather ability and resists water penetration.


Marflex DampProofing membranes are recommended for dampproofing below-grade basement walls of poured concrete or unit masonry construction. They serve as a vapor retarder on the exterior face of the interior walls of above-grade exterior masonry cavity walls. They also excel as a utility coating on posts, pilings and other metal surfaces set into the ground. Marflex DampProofing WB can be spray or brush/roller applied. SB Spray Only.
