The Problems

Without a proper drainage system, water can damage virtually any construction project. An improper waterproofing system can allow hydrostatic pressure to build, making any crack in the foundation an access for water damage.

The Solution

DELTA®-DRAIN is a highly effective drainboard that controls the flow of below-grade water. Its high water-flow capacity ensures effective drainage. This product is suitable for almost any application in residential and light commercial construction.

Outstanding compressive strength and impact resistance
Polypropylne drainage core allows incoming water to freely drain to the footing perimeter
Dimple pattern provides high compressive strength and acts as a highly effective protection layer for the waterproofing material during backfill
The heat-bonded polypropylene geotextile is securely bonded to dimple crowns by a thermal process for lasting durability and performance, and provides superb filtering performance
The geotextile is rot-proof, highly water permeable and prevents clogging of the flow passages in the drainage core. The result: continuous drainage of incoming water to the footing perimeter
Stabilized against chemical and environmental stress cracking
Tough and durable, the dimpled sheet can endure the rigors of jobsite installation
Available in 6′ and 8′ wide rolls, DELTA®-DRAIN is the largest size drainboard available on the market today, making installation quick and easy
