8 ft. x 65 ft. 7 in. Roll DELTA®-DRAIN Drainage Barrier (524.8 sq. ft.) | DELTA-DRN-8

DELTA-DRAIN Vertical Drainage Barrier is comprised of a 2-layer geocomposite. The first layer is the polypropylene drainage core that drains incoming water freely to the footing perimeter 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 heat-bonded PP geotextile. The rot-proof geotextile is highly water permeable and prevents clogging of the flow passages in the drainage core.

• 2-layer dimpled membrane
• Composed of special High-Density Polyethylene (HDPE) and PP non-woven TYPAR® geotextile
• Middle layer is manufactured with an exclusive co-extrusion process, utilizing 60% recycled HDPE
• Provides high compressive strength, impact resistance, and chemical and environmental stress crack resistance
