Protect your primary waterproofing investment with DELTA®-MS, the ultimate high-density polyethylene (HDPE) protection layer. Designed as a rugged mechanical barrier, it shields delicate waterproofing membranes from puncture and damage during backfilling. With its unique dimpled air-gap design, it not only provides a heavy-duty physical shield but also serves as a secondary drainage plane to keep hydrostatic pressure away from your structure.

Note: Used as a standalone membrane in USA, we do not supply accessories and mainly used as below grade membrane protection with better drainage and anti-condensation.

Available Size: 2M X 20M = 40M²

Product Details

The Professional Guard for Your Waterproofing System

In the construction industry, the most common cause of basement leaks is damage to the waterproofing membrane during backfill. DELTA®-MS eliminates this risk. It acts as a permanent, high-impact "protection board" that ensures your primary waterproofing stays intact and functional for the life of the building.

Engineered for Mechanical Defense:
Unlike thin protection fabrics, DELTA®-MS is made from tough HDPE that resists rocks, construction debris, and heavy soil loads. Its dimpled structure creates a 5/16" (8mm) air-gap, which relieves hydrostatic pressure by allowing water to flow freely to the footer drain rather than pressing against your wall.

Key Advantages for Protection:

  • Backfill Protection: Absorbs the impact of sharp rocks and soil during the backfilling process.
  • Secondary Defense: While its primary role is protection, the impermeable HDPE material provides a powerful secondary waterproofing layer.
  • Stress Relief: The dimpled design bridges cracks and allows the foundation to shift or settle without tearing the protection layer.
  • Lifetime Durability: Resistant to soil acids, alkaline, and root penetration, ensuring your primary membrane is guarded for 50+ years.

Product Limitations

  • Designed as a protection/drainage layer; check local codes if using as a standalone barrier.
  • Must be installed with dimples facing the wall/membrane for optimal drainage.
  • Not intended for permanent exposure to direct sunlight (UV).
  • Avoid using sharp-edged tools during installation that could puncture the HDPE.
