Application

Applied in waterproof structure,cross section of fix water stop or preventive injection hose.
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 

Base surface temperature.       Min+5℃ Max.+35℃
Environment temperature.      Min+5℃ Max.+35℃

Base surface humidity    Dry and no visible water

Tools 

■Applied for fixing water stop or placing injection hose.
Apply the sealant on base surface,if base surface is not flat,nozzle size need to be changed.
Fix water stop and injection hose to the sealant. Concreting 2 hours after sealant solidify .
■Applied for sealing of the construction joint

If the triangle nozzle is used, refer to the following instruction:

Building Thickness

30-50cm

20mm

3.6m

1.8m

Actual length of extruded sealant may be shorter because of condition difference.
■ Apply the sealant flat in the middle of concrete section.
Concrete edge: 10cm (reinforced concrete ) or 15cm (non reinforced concrete)
Concrete height: <50cm------- solidifying time:2-3 hours
Concrete height: >50cm-------- solidifying time:2 days
Press the sealant tightly during concreting to avoid cellular holes.
Clean Tools
clean all the tools and equipment when process finished

Conditions

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.
