TekDrain GDL Drainage Boards

TekDrain GDL Drainage Board is produced by laminating single-sided or double-sided
geotextile to a dimple sheet made of high density polyethylene (HDPE). It is resistant to
plant roots and decay. Thanks to the geotextile layer, it allows the water coming to the
shear wall to drain to the drainage pipes in the foundation ampacity frame.

• The star-shaped channels prevent the dimple from being easily crushed under pressure and increase the longterm strength performance.
• The geotextile allows the water coming into the wall to drain down to the drainage pipes, reducing the load on the wall.
• Laminated geotextile eliminates the need for extra steps and saves time.
• The void volume created by the star shape allows increased drainage capacity and free flow of water.
