Three-dimensional drainage structure
The raised dimple structure creates continuous cavities that provide drainage paths behind or beneath construction layers.
HDPE Drainage Board
Dimpled HDPE drainage board for drainage, water-pressure relief and protection of below-grade and landscaped structures.
Integrally molded from HDPE, the three-dimensional dimpled structure creates drainage channels for roofs, basements, underground structures and other construction applications.
Product Overview
0103
HDPE drainage board is an integrally molded drainage sheet manufactured from high-density polyethylene. Its raised dimple structure creates continuous cavities that provide drainage paths while forming a protective layer between the structure and surrounding construction materials.
Typical uses include basement roofs, floors and side walls, roof gardens and planted roofs, underground garages, tunnels and utility tunnels, landscaped areas, and selected drainage or pressure-relief works around dykes, dams and slopes.

Key Features
Water-pressure relief
The drainage layer helps collect and direct accumulated water, reducing water pressure around protected structures.
Protective layer
The formed HDPE sheet can provide a protective separation layer around waterproofing systems in below-grade and roof applications.
Multiple stud heights
Available stud heights from 8 to 60 mm provide options for different project configurations.
Lightweight installation
The sheet-form product is designed for practical handling and installation across building and civil-engineering applications.
