YURU OPU Hydrophobic Polyurethane Foam Grout

Oil soluble polyurethane grouting material (OPU Hydrophobic Polyurethane Foam Grout) by composite polyether polyol and poly isocyanate reaction generated by isocyanate terminated a chemical grouting material. The material meets the water after a chemical reaction, the volume expansion and generate a insoluble in water foaming body, can not only waterproof plugging, more certain reinforcement reinforcement effect, are widely used in the subway tunnel, water conservancy and hydropower, underground garage, and sewers waterproof plugging reinforcement engineering.

We offer OEM/ODM customization for packaging, labels, and product performance. Whether you need specific foam expansion ratios, curing times, or other performance characteristics tailored to your needs, we can customize the product to meet your project requirements.

Special Features

Features & Benefits

OPU Hydrophobic Polyurethane Foam Grout

Hydrophobic, expanding,chemical grout

Has good hydrophobic performance, high chemical stability.

Good chemical resistance

Acid, alkali and organic solvents, good chemical resistance.

Good bonding performance

Excellent bonding performance with concrete base and other building materials.

Adjustable as needed

The viscosity and cure rate of grouting material can be adjusted according to the engineering requirements.

only a small amount of water is needed for reaction

With a larger infiltration radius and solidification volume ratio, the water in the case of rapid chemical reaction, and will produce a large expansion pressure, to promote the formation of the slurry to the cracks in the formation of a strong consolidation of the consolidation.

hydrophobic polyurethane foam grout Application

The pool, water tower, basement, grouting shelter and other buildings.

Underground tunnel, building foundation reinforcement and ground dust treatment.

Deformation joints, construction joints, cracks in the construction of the building, plugging and reinforcement.

Port, wharf, bridge pier, dam, dam, hydropower station, curtain grouting, plugging and reinforcement.

The geological drilling wall plugging, water gushing water and mine selective oil exploration in the block.

Injection Grout steps

hydrophobic polyurethane foam 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.

Fast logistics, the goods are intact, the quality exceeds expectations, very satisfied.

Frequently Asked Questions

We have compiled the most frequently asked questions about our waterproof coating paints here for your convenience, but please feel free to contact us if you have any additional questions.

What is the role of oily polyurethane grouting material？

Oily polyurethane grouting is a polymer grouting plugging material, mainly used for rapid plugging and structural reinforcement. It is injected into the concrete, expands and solidifies after chemical reaction with water, and achieves the purpose of complete water stopping.

How Can I Get a Quote For The Injection Grout Material?

Yes, please contact customer service to obtain a reasonable and accurate quote for grouting materials. Include specific details, including but not limited to quantity and packaging specifications.

What is Your MOQ For The Order?

With MOQ of only 100kg, you can ensure your order. Meanwhile we support customized orders.

What is The Turnaround Time On My Order?

It takes us around 2 to 6 business days to produce the injection grout materials. On the other note, the transit time will take 10 to 15 business days. Reach us online for your custom and bulk orders so we can explain the actual turnaround time based on the specific details of your order.

Can I Get a Sample Before Place The Order?

Surely! You can always request a sample before place the bulk order. Sample time usually will take 2-3 days, depends on the specifications you need.
