sbs waterproof membrane take the “Skin” type waterproof thought, according to the features of construction site, on the basis of width elastomeric modified bitumen waterproofing membrane, combining with features of wet-application self-adhesive membrane, use advanced equipment to produce 2 meters width that WP-SBS wet-application width elastomeric modified bitumen waterproofing membrane (Hereinafter referred to: WP-SBS membrane).WP-SBS is made of bitumen modified with Styrene-Butadiene- Styrene (SBS)as dipping and painting. Its upper surface covers PE membrane and color sand or schist, and lower surface is made of isolation material. Products correspond to the national standards GB18242-2008(elastomeric modified bitumen waterproofing membrane), paste by cement or cement mortar, and construct on the wet base, achieving tight and full adhesion with substrates, eliminating fluid-channeling layer, all above contribute to making a reliable “Skin” type waterproof system, which is a breakthrough innovation in ordinary modified bitumen membrane.

2.Possess good tensile strength, elongation and size stability which could be well suited the substrate distortion and crack.
3.Good performance in anti-strength, anti-resistance , anti-erosion, anti-mildew, anti-weathering
4.SBS modified bitumen membrane is specially being applied in the cold area with low temperature, while APP modified bitumen membrane is applied in the area with high temperature.
It is widely used for civil building roofing, underground, bridge, parking, pool, tunnel in the line of waterproofing and dampproofing, especially for the building under high temperature.
1.Make sure the roof deck smooth ,clean and dry(Moisture<9%),then apply the surface of roof deck homogeneously with a kind bitumen paint till dry to start application.
2.There are two methods in application:
One way is by heating and melting method---Heat the polyethylene film of the membrane and roof deck surface by heating and melting method to be nearly melted (not flowing),then install the membrane fully bonded to the roof deck with overlaps of 5-10cm.
The other way is by cold adhesive method---Pour the cold adhesive homogeneously on the roof deck then roll the membrane to install it to be fully sticked to roof deck.
By heating and melting method and by cold adhesive can be used in alternation in application as requested.
3.After application ,a full serious inspection is required to make sure no air bubble ,no fold,no falling away etc to guarantee the waterproof life.
