Key features

• Pre-applied: fixed before placing reinforcement and casting concrete
• Post-applied: fixed after concrete has cured minimum 28 days
• Can be applied on damp or green concrete
• High flexibility and crack-bridging capabilities
• No lateral water migration between concrete structure and membrane
• Fully and permanently bonded to the reinforced concrete structure
• Not affected if water table rises and falls
• Resistant to aggressive conditions in natural ground water and soil
• Selvedge on one side for self-adhered laps
• Virgin (non-recycled) HDPE
• Temporarily resistant to weathering and UV exposure during construction
• VOC free, eco-friendly material
• Sound anti-puncture performance

Applications

• Damp-proofing, waterproofing and concrete protection for basements, subways, tunnels and other below ground concrete structures
• Reinforced concrete base slabs
• Reinforced concrete walls with single and double-faced formwork
• Reinforced concrete footings and grade slab
• Extension and reconstruction works
• Prefabricated structures
