Description :

Fully bonded HDPE membrane for waterproofing underground structures.

Advantages :

• Mapeproof AL AP is a robust membrane that is highly resistant to both puncturing and tearing.
• Mapeproof AL AP, once concrete has been poured, forms a monolithic bond with it and remains perfectly bonded over time.
• Mapeproof AL AP is a waterproofing system that becomes fully bonded to poured concrete. It prevents water from migrating laterally between the foundation structure and the membrane.
• Completely watertight overlaps.
• Mapeproof AL AP is cold applied (no heat and/or naked flames are required), before installing steel reinforcement and
  pouring concrete and does not require a protective layer.

Technical Characteristics :

Mapeproof AL AP is a waterproofing membrane made up of a synthetic HDPE sheet with an adhesive side covered with a pressure sensitive protective coating.
When it comes into contact with poured concrete, it forms a tough bond with it.
Mapeproof AL AP is resistant to aggressive natural agents normally found in groundwater and soil. It is durable and resistant to ageing by UV rays during normal site operations.
Mapeproof AL AP provides an effective barrier to groundwater, soil moisture, radon and methane gas.
Mapeproof AL AP meets the requirements of EN 13967 (“Flexible sheets for waterproofing – Plastic and rubber damp proof sheets including plastic and rubber basement tanking sheet”).
