Advantages of rubber water stop:

1. High expansion rate, strong mobile supplementary.

2. Strong self-healing, can plug tiny cracks resulted from Concrete shrinkage and settlement.

3. Simple, convenient and reliable operation, best corrosion resistance.

4. Can provide a variety of specifications according to the need of design and construction



Most popular way of the placement of the water stop seal is tied to the steel frame works or small eyelet by means of small wires, certain metal clamps made to grip the water stop seal to keep it in proper position. Our waterstops are profiles based on specially formulated plasticized PVC compound, which are designed to meet specific requirement of building industry. It is essential that a device is used against potential risk of discomfiture that tends to be caused in concrete structure following climatic, geo-disturbances and frictional impasse which result in expansion or contraction in concrete structure. And the expansion or contraction results in leakage/seepage of water exposing the structure to bring the risk of cracks or dismemb erment.


Rubber Water stop is widely used in underground installation, tunnel and culvert, impounding reservoir, metro, and retaining dam and so on.

Company Information



  Beijing Langwei Times Sicience & Techonlogy Co., Ltd


 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.
