EPDM Rubber Waterproof Roof Membrane of Waterproof Material

EPDM Rubber waterproof coil is mainly composed of ethylene—propylene—butadiene terpolymer synthetic single layer cure type rubber macromolecule homogeneous sheet. It owes complete saturation molecular chain and the molecular structure is stable, its excellent physical performance remain unchanged for long, convenient installation and maintenance turn it into one of the most mature and most widely used waterproof material. 

1. Excellent weather resistance, aging resistance, oxidation resistance and long service life
2. With high elasticity, high strength, high and low temperature resistance and excellent physical properties.
3. Perfect anti-crack performance, strong adaptability to contraction and cracking of basic level.
4. A complete series of matching products , fast and convenient installation and maintenance
5. Offers a variety of width and thickness of the material according to engineering demand.

        LangWei Conchem is a fast growing international manufacturer of construction chemicals with plants in Beijing, China. The company is specialized in preventative and remedial waterproofing products.

        Preventative waterproofing products are wildly used during new construction and are usually installed by the general contractor. Examples are bentonite strips, hydrophilic mastics and rubbers, which swell in contact with water and hence block water ingress, injection hoses, which can be injected at a later stage to block water and finally cementitious coatings for basement waterproofing and elastomeric membranes for tanks and roofs.

        Remedial waterproofing products are mostly used when major (or minor) water leaks happen at a later stage and are usually applied by specialist applicators. Remedial waterproofing products are also often used during construction of tunnels and other underground constructions to prevent infiltrating water from hindering the normal progress of the works. Examples are injection resins based on Polyurethanes (both 1C and 2C) and Poly-acrylates. These products are also used for Soil and Rock Stabilization, together with Organo-minerals.

        LangWei Conchem also manufactures a series of products for the Protection and Repair of reinforced Concrete. Examples are cementitious grouts and mortars, epoxy injection resins, carbon fibre laminates and epoxy glues.

        LangWei Conchem is specialized in preventative and remedial waterproofing products, which are mostly used in Balcony waterproofing, car part decks, concrete repair and protection, facade waterproofing, flooring systems, injection equipments, packers & accessories, preventative waterproofing, remedial waterproofing, roof waterproofing, sewer rehabilitation, soil injections, tunel applications and so on.
