SBS/APP 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.
Self adhesive waterproofing material is made by saturating the base in bitumen, or thermoplastic elastomer (such as styrene butadiene), reinforced with polyester or fiberglass, finishing the upward face with fine sands, mineral slates (or grains) or polythene membrane etc. It has the outstanding performance such as: convenient to apply, no environmental pollution etc. This product is consisting of two kinds: without reinforcement and polyester reinforcement.
1.Good flexibility, creep properties and ductility, has strong ability to adapt to the deformation of the base layer. 2.Self-healing ability, waterproofing layer can adhesive closely with the base layer. 3.Cold construction method, have strong lap joint reliability and base layer adhesion reliability. 4.The lap joint between membrane and base layer is voluntarily spliced. Convenient and safe to apply. Won’t cause environmental pollution. 5.Self adhesive waterproofing material can be applied on damp base layer using damp-spread construction method, using polymer cement plaster as the splicing dose. Quick to apply and adhesion is reliable.
