Key features

• Pre-applied: fixed before placing reinforcement and casting concrete
• Strong adhesive bond with fresh concrete
• High flexibility and crack-bridging
• No lateral water migration between concrete and membrane
• Made from non-recycled / virgin HDPE
• Temporarily resistant to weathering and UV exposure during construction
• Heat-weldable selvedge for thermal jointing
• Chlorine, plasticizer and phthalate free
• Good resistance to heat and ozone
• Reinforcement can be laid directly on membrane (no screed protection)

Applications

• Basements
• Subways
• Tunnels and other below-ground concrete structures
• Reinforced concrete base slabs, footings and grade slab
• Confined reinforced concrete walls with single-faced formwork
• Extension and reconstruction works
• Prefabricated structures
