1. Product Description

 

SBS Waterproof Membrane using polyester reinforcement for waterproofing is a new type of wateproof material,it's made from polyester felt as its reinforcement featuring high strength,elongation amd corrision resistance, SBS compound as its modifier for meeting the torched-on applications, it shall be covered with polyethylene membrane(PE),aluminium foil, colorful sand or mineral granule on its top surface and polyethylene membrane(PE) coated on its under face. This series of membrane is designed for the waterproofing of underground construction such as tunnel, subway, basement,roofs and pools etc.

 

2.Characteristic

• Good impermeability
• Thinckness: 3mm,4mm,5mm
• Length:8m,10m or customed
• Being applied in the cold area with low temperature:0°C, -5°C, -10°C,-20°C, -25°C
• Good performance in anti-puncture, anti-broker, anti-resistance, anti-erosion, anti-mildew, anti-weathering
• Possess good tensile strength, elongation rate and size stability which could be well suited the substrate distortion and crack
