Good Tearing Strength PVC Waterstop For Expansion Joint Building Project



Product Description



PVC water stop adopt PVC as a main material, possessing favorable flexibility, durability, ageing-resistance and weldability, added injection pipe and injection hole in two side end of water stop, i.e. added holistic sealed second waterproof line. New highlights of LW water stop as following greatly improved the waterproofing of construction joints.



High performance, corrosion-resistance, aging resistance, high strength, high tear resistance

Welding on site easily and fast, joint quality is good.

Design of setting hole on both strip side makes mounting easily and accuracy.

Grouting through injection hose on side to repair leakage at construction joint or concrete joint economically.

Test the mounting result by water-pressure test on site.

According to requirement of projector available offering water stop of various specification.

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, tunel applications and so on.
