Waterproof High Polymer HDPE Self Adhesive Bitumen Waterproof membrane
APPLICATION
SBS/APP modified bitumen membrane is used as waterproofing/damp proofing membrane for protection of various substrates in wide
range of applications which included the following:
• Roofs
• Terraces, balconies & patios
• Sunken slabs
• Concrete foundations & footings
• Basements
• Pile heads
• Bridges & tunnels
• Airport aprons & ramp areas
ADVANTAGES
• High resistance to positive water & vapor pressure
• Good dimensional stability under tension
• Excellent flexibility
• High puncture and fatigue resistance
• High tensile and tear strengths
• Resists water borne chemicals
• Accommodates structural movement
