The product is comprised of a 2-layer geocomposite. The first layer is the high-density polyethylene drainage core that drains incoming water freely to the footing peri-meter drain, thus preventing the build-up of hydrostatic pressure against the waterproofing layer. It also acts as a highly effective protection layer for the waterproofing material during backfill operations. The second layer is a heatbonded PP geotextile. The rot-proof geotextile is highly water permeable and prevents clogging of the flow passages in the drainage core.

Features:

• Composed of special High-Density Polyethylene (HDPE) and PP non-woven TYPAR® geotextile
• The middle layer of DELTA®-DRAIN is manufactured with an exclusive co-extrusion process, utilizing 60% recycled HDPE
• The two thin outer layers are composed of a specific grade of virgin HDPE

Benefits:

• Outstanding compressive strength and impact resistance
• HDPE 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
• The product is environmentally friendly
• The two thin outer layers, composed of virgin HDPE, protect the recycled HDPE from polymer degradation caused by oxidation and environmental influences like acidic soils or alkalinity (concrete)
• Stabilized against chemical and environmental stress cracking
• Tough and durable, the dimpled sheet can endure the rigors of jobsite installation
• DELTA®-DRAIN is the largest size drainboard available on the market today, making installation quick and easy
