Key features

• Fully adhered to poured concrete, prevents water migration
• Unaffected by hydrostatic pressure
• Unaffected by contamination
• can be cleaned with water/high-pressure air
• No special tools or welding techniques
• Chemically resistant in all soil conditions incl. salts
• Fully adhered watertight laps

Applications

• Basement rafts and confined retaining walls with high water table
• Cut and cover structures (e.g. tunnels)
