The dimpled design allows concrete to breathe while directing and controlling moisture around below-grade walls and flooring assemblies. System Highlights Material HDPE High-density polyethylene Membrane Type Dimpled Creates a drainage air space Primary Use Below Grade Foundations and flooring Crack Bridging Up to ¼ in. Bridges compatible foundation cracks Key Benefits Strong HDPE Construction Manufactured from durable high-density polyethylene for long-term below-grade performance. Basement Leak Protection Helps manage moisture and address water-infiltration problems around basement foundation walls. Waterproof Vapor Barrier Creates a continuous protective layer that helps control moisture and vapor movement. Drainage Air Space The dimpled profile creates an air gap that allows concrete to breathe while directing moisture downward.
