Professional accessories,don't need special installation tools. The length can be cut out according to job location.
1.Types
a)SAYA1 subway tunnel grouting pipe.This products mainly apply to waterproof system of construction joint,structural joint,baseboard joint in subway
and tunnel projects.
b)SAYA9 subway tunnel grouting pipe.
This products mainy used for concrete joint parts of subway and tunnel that have the possibility of leakage.
2.instructions
a)Provide professional accessories,no special installation tools.The length can be cut out according to job
location.b)Installing the product process won't destroy concrete strength.c)When high-pressure grouting,the chemical grout can keep uniform and fill the pipe,then infiltrated into the
concrete.d)no leakage can not grouting,but after grouting to make sure seal permanent.
