DELTA®-DRAIN

The Problem

Floor slabs collect moisture and mold when composed of porous concrete. In order to protect a building’s foundation and provide longevity, proper moisture control is necessary. A sub-base course will protect the footing and prevent the concrete from pulling water up from the dirt, preventing moisture from seeping through walls, floor and joints. 

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. 

DELTA®-DRAIN
Product Details
Product Benefits
  • 2-layer dimpled membrane
  • 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 
  • 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
  • Composed of 60% recycled HDPE, 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
  • Available in 6' and 8' wide rolls, DELTA®-DRAIN is the largest size drainboard available on the market today, making installation quick and easy
