Unique Waterproofing Membrane Based On Hdpe And Sodium Bentonite For Below Grade Areas.

Product:
The Dual Seal® waterproofing sheet membrane combines the strength, chemical and puncture resistance of high density polyethylene (HDPE) with the expanding self-sealing capabilities of Sodium Bentonite Clay, to form the most unique waterproofing system today.

Advantages:
• Self-healing
• Prevents tracking of water between membrane and concrete surfaces
• Resistance to hydrostatic water head of 46 m
• Over 100 years of life expectation
• High puncture resistance
• Non-toxic and environmentally friendly
• Quick and easy installation over green concrete
• Does not require priming and heat welding
• Installation temperature -30°C to +55°C

Usage:
The HDPE and Sodium Bentonite are laminated together to form a tough sheet membrane. It is easily installed and typically applied on below grade civil engineering constructions such as: sub level walls, cut and cover tunnels, under structural slabs and subways.

System:
1. Water enters
2. Bentonite hydrates preventing further water penetration
3. No tracking of water between membrane and concrete
