High Polymer HDPE Self Adhesive Waterproof Membrane

Pre-applied, Fully Bonded HDPE Waterproof Membrane
DescriptionMulti-layer composite: high density polyethylene (HDPE) film, high polymer adhesive layer, and unique process reaction-type inorganic polymer particle;
High-quality raw material: with high density polyethylene resin as the raw material, mixing inhibitor, antioxidant, UV absorbent, stabilizer and other functional materials, and adopting international advanced injection molding and rubber mixing technology.
High adhesive strength: adopting macro-molecular binding material and pre-processing quartz material for strong adhesive strength with concrete.Feature
1. Forms permanent bond to concrete poured against it, preventing water from seeping into the gap between waterproofing membrane and the structure2. Not affected by the displacement of the basal layer/ ground settlement beneath slabs3. Membrane is self-protecting. It can be trafficked immediately after application and does not require the use of protective layer
4. Simple and quick to install, requiring no priming or fillets5. Unaffected by wet conditions6. Fully-adhered watertight laps and detailing7. Excellent bonding even under long-term water immersionBenefit
1. Forms long-last bond to concrete, preventing water from seeping into the gap between waterproofing membrane and substrate
2. Not affected by the displacement of the basallayer/ground settlement beneath slabs3. Sand layer makes it possible to construct and work on membrane after applied without protective layer4. Simple construction process5. Membrane can be applied at -4ºC and above6. Unaffected by wet conditions7. Fully-adhered watertight laps and detailing8. Excellent bonding even under long-term water immersion
Main Application1. Waterproofing below ground concrete structures2.Protection of concrete foundations against aggressive ground contaminants3.Prevents methane leakage in underground layers

Application Instruction
The membrane should be overlapped using steel roller to ensure complete bonding and to achieve continuity. It can be installed at temperatures of -5ºC and above. When installing itin cold weather, care should be taken to preheatthe bonding edge with appropriate means such as hot air gun or other similarmeans.Precaution
After the complement of the waterproof course, pay attention to protect the course and avoidthe damage. During the construction and before the acceptance of the project, all the personnel are prohibited to walk above thewaterproof course wearing spike.
