Drainage Dimpled Sheets

General Information It is dimpled structure drainage and underground insulation protection board., made of high density polyethylene(HDPE), has high compressive strength, resistant to plant roots and chemicals. Product description Serves as a protection layer throughout backfill work and prevents below-grade water from penetrating the structure. Allows for vertical and horizontal installations. Mainly used for the following applications: underground structures, basements and retaining walls, tunnels, underground car parks. KEY FEATURES & BENEFITS Provides drainage and protection for compression-resistant areas. Keeps incoming water off the waterproofing material and allows in to freely drain to the drainage pipe. Minimizes the risk of damage to the waterproofing layer underneath the membrane when backfilling. Dimples between the basement wall and the membrane form an air gap which keeps the structure dry and moisture-free. Low-cost alternative to the sub-foundation lean concrete including the following advantages: faster installation, no extra equipment is required. No degradation in the soil, thanks to its rot-proof material Completely non-polluting for drinking water. High compressive strength. Distributes the load evenly across the surface.
