    "Bondsure"BAC Polymer Composite Self-adhesive waterproof Membrane is comprised of polymer sheet(HDPE,EVA,ECB, Polyethylene polypropylene fiber),self-adhesive rubber asphalt compound,isolating membrane. As requirement, it can be reinforced by combining fabric with the polymer sheet. With the merits of both polymer waterproof rolling material and self-adhered membrane, the penetration resistance,weather-resistance,self-healing property, high and low temperature resistance of this waterproof Membrane are improved dramatically. And its physical properties and chemical property are good.Due to the waterproof Membrane strongly stuck to secondary lining concrete, basically, the deficiencies in structure are covered up by this flexible "Skin". And the breakage basically is filled by secondary lining concrete. Here,it is seen that defective BAC membrane perfectly matches with imperfect secondary lining,which forms into an impregnable waterproof system.

Performance Charcteristics of BAC Polymer Composite Self-adhesive waterproof Membrane1. The way of setting one layer for waterproofing and the other two layers for Prevention from leakage is more effective and reliable. This membrane is with the advantages of both Polymer waterproof Membrane and self-adhered membrane which drastically improves its property of puncture resistance, weather resistance, self-healing, high and low temperature resistance.Its physical property is good and chemical property more stable.2. Self-adhered compound layer is made through an exclusive prescription which can form a interpenetrating polymer networks with cement molecular and make the waterproof membrane and waterproof project become an integral whole(impermeable after even long-term immersion in water). 3. Ways of overlapping are flexible. Depending upon Actual project situation, seal patterns like cool Self-viscous" sticker to sticker" welding polymer membranes or double sided self-adhered tape is optional4. Methods of construction are flexible. depending site Conditions, the membrane is open to various methods of construction like wetting and spreading,suspending lay-up, mechanically fixing, hanging lay-up,which are flexible and they are more effective in waterproofing.5. Requirements over base are low,shortening construction period.it is workable on the bases wet or even rough without base coating or pretreatment. Degree of construction freedom is high regardless of weather condition,which would save construction time dramatically. 6. Totally pollution-free. It is no need to get any solvent or fuels involved,avoiding environmental pollution or fire control incipient fault and saving energy as well.7. Construction method of "Pre-laid"(external protection layer stuck inside) filling domestic gaps in waterproofing,solving historic problems.
