HDPE Sand Coated Waterproofing Membrane

HDPE Sand Coated Waterproofing Membrane

HDPE Sand Coated Waterproofing Membrane is a unique HDPE based self adhesive fully bonded sheet membrane comprising of a virgin HDPE layer, coated with a high bond strength adhesive, covered by a weatherproof protective sand sprinkled layer, for below ground waterproofing of reinforced concrete structures. It is loose laid onto prepared substrates or formwork before fixing reinforcement and casting concrete.

The adhesive layer is activated when the concrete is poured on the surface and forms a permanent bond with the fresh concrete which will prevent the ingress of water around the structure. Reinforcement can be directly laid on top of the membrane and it does not require screed protection..

HDPE Sand-Coated Membranes are specially designed membranes that have a sand-coated or textured layer to enhance friction, bonding strength, and stability:

• ✔ Basements & Substructures
• ✔ Tunnel & Underground Construction
• ✔ Landfills & Solid Waste Management
• ✔ Bridge Abutments & Retaining Structures
• ✔ Canal Lining & Water Channels
• ✔ Tunnel Shotcrete Applications
• ✔ Vertical Wall Protection
• ✔ Dams & Reservoirs
