Special Features

Features & Benefits

WPU Hydrophilic Polyurethane Grout

Low viscosity

Low viscosity, fast in water dispersion reaction, the formation of elastic colloidal insoluble solid, with plugging sealing performance is good.

anti permeability

The formation of white elastic colloidal solid and water, with high compressive strength, low temperature resistance, good elasticity, anti permeability and other features.

Sealing leaks

The product is mixed with water and the effect is good, can penetrate into deep cracks, crack filling a full range of institutional consolidation after the formation of the reaction.

good hydrophilicity

The expansion of the product is good, the amount of water is large, with good hydrophilicity and irrigation, and the viscosity of the product and the curing rate can be adjusted according to the project.

Injection Grout steps

Hydrophilic polyurethane grout Construction Steps

01 Cleaning:

Carefully check the water leakage site, identify the leak, remove the dirt around the crack.

02 Punch:

In leakage cracks on both sides of the cross hole spacing is 200-500mm, the leak can be intense.

03 Burying water stop needle:

Holes where buried good fit the length of the needles in the, and then one by one tightly needle, let parts of rubber inflation and deflation in wall body, hands touch not shaking so far.

04 Grouting:

High pressure grouting can be taken, from bottom to top one by one to control the pressure in the needle, to see the adjacent cracks at the bottom of the pure pulp.

05 Knock out needle:

After grouting, use a small hammer to gently knock out the needle outside the concrete.

06 Storage and transportation：

Stored in a dry, cool place.

The collision, transport may not be straight sun, rain, prevent fireworks.

The logistics is fast, the goods are intact, the product quality is good, it is used for waterproofing repairs on roof gaps, the effect is good, and I am very satisfied.
