Company Information

 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, tunnel applications and so on.
