waterproofing membrane bitumen

SBS modified bitumen waterproof membrane is saturating the membrane base with modified bitumen, thermoplastic elastomer (styrene butadiene-SBS), reinforced with polyester or fiberglass, with fine sand, mineral slate(or grains)or polythene membrane on top.

1.Good impermeability

2.SBS modified bitumen membrane is specially being applied in the cold area with low temperature

3.Good performance in anti-puncture, anti-broker, anti-resistance, anti-erosion, anti-mildew, anti-weathering

4.Possess good tensile strength, elongation rate and size stability which could be well suited the substrate distortion and crack.

Suitable for civil building roofing, underground, bridge, parking, pool, tunnel in the line of waterproofing and dampproof, specially suitable to low temperature(APP specially suitable to high temperature and of atrong sun-shining) .
