Product Description

 Re-injectable grout hose is one of the specially designed solid PVC injection pipe systems. It can be mounted on the internal cement joint, used to waterproof and seal any gaps and holes on the joint area. It can seal joints then make them water-tight, if leakage appears in the future, we can also provide complete maintenance program. LW system can be used to repeated grouting when portland cement, fine cement or acrylic grouting resin used. Using LW re-injection pipe system (Re - inject) can improve waterproof technology. The advanced grouting system can exactly realized "zero leak;. In addition to its advantages of easy installation and reasonable price, LW system can also simplify the work and make sure the joints not leaking.


1)Can pass leaking test

a. Can confirm the sealing property of the construction joint at scene

b. To grout only when the joint leaking

2)Hose can be unlimited re-injected

a. If there are still crack or new cracks, hose can be grouted again, effectively reduce the complicated process of changing tools

b. Neoprene as one-way valve can effectively prevent the grouting back flowing under backpressure

Rigid core

c. Won't be pressed flat under concrete pressure so as to make the use of the grouting unobstructed

3)Resistance to chemical corrosion

a. The material is durable, contains no metal, will not be corroded when contacting with polyurethane, ethylene resin, epoxy resin or cement,  


Expediently placed in the corner, no need to cut and connect.

Grouting materials:

Suitable grouting material must meet the requirements of the joint. Here are two kinds of grouting material are alternative. Want to know more information, please contact Beijing Lang Wei times science and technology co., Ltd.

1. GI acrylic resin: Water swellable 1.5 times. GI acrylic resin is a kind of low viscosity resin,  which can penetrate fine cracks and capillary and seal them permanently. Acid, alkali, many solvent and fuel resistance. It is easy to clean the equipment and tools which are polluted by this resin with water.

2.  SI superfine cement: a kind of single compound, micro cement based on the state of suspending liquid, use directly. SI can mix with water in high speed, form a kind of low viscosity, high permeability cement suspended matter. This fine property makes it able to penetrate the subtle gap, seal them reliably.


Stored in a cover place, avoid oil, dirt, concrete rubble  and others getting into the hose.

Quality guarantee period:

According to the suggestion way in the seal and original conditions, it can be stored permanently

Company Information

Advanced Performance & Technology Re-injectable Acrylic Grout Injection Hose

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.



With consummate production technique and advanced equipment, Langwei Times is known as one of the leading advanced performance & technology re-injectable grout injection hose manufacturers and suppliers in China. you are rest assured but cheap advanced performance & technology re-injectable grout injection hose online with us.
