ZT-108 Water soluble polyurethane injection grout
- Implementation standards：
It is a polymer compound that mainly made up by toluene diisocynate and trihydroxy-soluble polyether. It can be reacted with water, the volume expands quickly so that seals and blocks the leakage passage rapidly.
After reacting with water, it solidifies as elastic colloidal solid in seconds
Convenient and efficient
Low viscosity,good grout ability and simple equipment.
Well waterproof effect
Good anti-permeability, high strength, large expansion rate and well supporting stability.
It reacts with water, and releases carbon dioxide then foams and swells. Meanwhile, it has secondary waterproofing.

Key points for construction
Enlarge the leakage, chisel it as a V, and swash with water.
Bury grout nipple in the V groove, and fix with plugging cement.
Grout into the V groove with grouter till it is full, and truss the grout pipe in case overflowing (Control the pressure in 0.2-0.3Mpa).
Cut the exposed grout nipple when it solidifies, and flatten with cement mortar. Bury grout nipple in the V groove on tiny cracks with a 65°angle.
Workers need to wear good labor protection supplies;
Cans injection slurry, keeping a close eye on pressure gauge instructions, prevent the grouting pipe burst;
Fight the eyes paste and stick on the skin, otherwise please use amount of top water wash or go to a doctor to the hospital.
Where To Use
Leaking stoppage of tunnel, colliery, well drain, dyke, wharf and other underground structure;
Leaking stoppage and seal of construction joint, settlement joint, deformation joint, lap joint and other distress in concrete.
Storage and Transportation
Product should be stored in ventilated, cool, dry place, away from the fire. Transportation should beware of weathered, prevent collisions and beware of extrusion.
