waterproof

Construction joint

Pipeline and concrete iron in wall or cement board

Surrounding the concrete iron or joint

Inner joint of cable

Fix

Preventive injection hose: type LWRI, I and II

Cross section of water stop

Procedure

Base surface must be sound, clean, dry, no oil or dust,etc.

Clean all practical, demolding agent, bleeding cement, old coating film and other loose animals.

Construction Conditions

Min+5℃ Max +35℃

Base surf. Temp.     Min+5℃ Max.+35℃

Environment Temp.    Min+5℃ Max.+35℃

Base surf. humidity    Dry and no visible water

Conditions 

LW swell sealant will expand some hours after water contact. It is not allowed to stay a long time in water (water draining complete in 24 hours) before concreting.

Placing  the sealant in movable crack is not allowed.

When water level rise, the sealant expand and sealed the crack.

In drying condition, the sealant shrinks to original size; but will re-expand when touching water.

Suggest to apply the sealant under less than 2 bar pressure  (test pressure is 5 bar) because of sealing width limit.

If the pressure is high than 2 bar, the sealant can be used to fix the injection hose.

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.
