Non Curing Liquid Rubber Modified Bitumen Waterproof Coating
DescriptionNon- curable rubber modified asphalt waterproof coating is made of high quality petroleum asphalt, functional polymer modifier and special additives through scientific optimization.
Advantages
1. High solid content, more than 98%, no solvent or volatile matter.
2. Never be solidified. Always keep the state of creeping viscous paste, can resist the deformation of substrate.
3. Always keep excellent creeping property. Good self healing ability. Able to heal the concrete automatically, suitable for complex construction surface.
4. Strong adhesion to different kinds of substrates and membranes. Excellent bonding performance.
5. Can be used below -20ºC.
6. Wide range of application. It can be used on the wet surface without visible water and any other surface that made from various materials.
7. Easy to apply. Both brushing and spraying are ok.

Description
Multi-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 structure
2. Not affected by the displacement of the basal layer/ ground settlement beneath slabs
3. 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 fillets
5. Unaffected by wet conditions
6. Fully-adhered watertight laps and detailing
7. Excellent bonding even under long-term water immersion
Benefit
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 basal layer/ground settlement beneath slabs
3. Sand layer makes it possible to construct and work on membrane after applied without protective layer
4. Simple construction process
5. Membrane can be applied at -4ºC and above
6. Unaffected by wet conditions
7. Fully-adhered watertight laps and detailing
8. Excellent bonding even under long-term water immersion
Main Application
1. Waterproofing below ground concrete structures
2. Protection of concrete foundations against aggressive ground contaminants
3.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 it in cold weather, care should be taken to preheat the bonding edge with appropriate means such as hot air gun or other similar means.
Precaution
After the complement of the waterproof course, pay attention to protect the course and avoid the damage. During the construction and before the acceptance of the project, all the personnel are prohibited to walk above the waterproof course wearing spike.
