Water Based Polyurethane Injection Grout Construction Grouting Waterproofing Material Cement


Product Description


Polyurethane grout by the high activity polyether,curing agent, a reinforcing agent for the chemical synthesis of the polymer grouting material. 
The material with water or air expansion foam solidification to plug cracks and pores,the formation of rigid contraction of colloidal concretion body

,so as to achieve a good sealing purposes,is a new generation of waterproof sealing material used to strengthen.


Product Feature


1,Low viscosity, quick reaction in water, forming impervious elastic colloidal concretion body by 


   reaction with good water sealing performance.


2,Reacting with water, it forms ivory elastic colloidal concretion body, which has the advantages of 


   high compressive strength, low temperature resistance,good elasticity and penetrationproof quality.


3,Good effect on mixing with water. The product can penetrate into crack deeply and the crack can be 


   sealed thoroughly by concretion body.


4,Good dilatability,big water content ,good water affinity and groutability, meanwhile the viscosity and


   curing speed can be adjusted according to customer's requirement. 





1.Hydrophilic and hdrophobic kinds
2.Function:stop water, void filling, reinforce
3.Used in coal mine, dam, tank and more


4.VOC or solid content is 70%~100%


5.activated fast with water


6.the solidify product can swellable with water

Company Information

As an member of Chemical Grouting Sub-Committee, Chinese Hydraulic Engineering Society, the Director Member of Waterproof Sub-Committee and China Construction Industry Association.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.
