Drainage Board with Geotextile and Dimple Sheet

Drainage Board with geotextile is a high performance HDPE dimpled sheet designed to provide effective drainage and protection for underground structures. The dimpled core creates a continuous air gap that allows water to flow freely, reducing hydrostatic pressure on foundation walls while protecting waterproofing membranes.

The integrated nonwoven geotextile layer acts as a filtration system, preventing soil particles from clogging the drainage channels. This combination ensures long term drainage efficiency and structural protection in demanding construction environments.

Available in 8 mm and 10 mm thickness options, this drainage board system is widely used in foundation walls, basements, retaining walls, tunnels, and landscaping projects. Compared to traditional gravel systems, it offers faster installation, reduced cost, and consistent performance.
