DELTA®-DRAIN

The Problem

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. DELTA®-DRAIN is suitable for almost any application in residential and light commercial construction.

Product Details
Product Benefits
  • 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.
  • Two thin outer layers are composed of a specific grade of virgin HDPE 
  • 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
  • Heat-bonded polypropylene geotextile is securely bonded to dimple crowns by a thermal process for lasting durability and performance, and provides superb filtering performance
  • 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
  • Composed of 60% recycled HDPE, the product is environmentally friendly
  • 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
  • Available in 6' and 8' wide rolls – the largest size drainboard available on the market today, making installation quick and easy
