The Problems

It's important to have a reliable drainage system in place to prevent water damage in any construction project. If the waterproofing system isn't done correctly, hydrostatic pressure can build up, and even the smallest foundation crack can become an entry point for water damage.

The Solution

DELTA®-DRAIN Horizontal is a highly effective drainboard that controls the flow of below-grade water in horizontal applications. Its high water-flow capacity ensures effective drainage and maintains that drainage space thanks to a special geotextile that will not rot and prevents clogging. The drainage board is designed to last with high compressive strength and high impact, chemical and environmental stress crack resistance.

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

Product Benefits
  • 2-layer dimpled membrane
  • Composed of recycled polypropylene.
  • Typar fabric heat-bonded to dimples.
  • Outstanding compressive strength and impact resistance
  • Polypropylene 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
  • 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 – the largest size drainboard available on the market today, making installation quick and easy
