what is PU waterstop grouting material

The PU Waterstop grouting material series includes single-component and two-component formulations that are typically low viscosity and hydrophobic.

In construction, civil engineering, and infrastructure projects, PU waterstop foam is commonly used for applications such as basement waterproofing, tunnel sealing, and concrete repair.

The key advantages of polyurethane grouting materials include high flexibility, excellent adhesion, and strong resistance to chemicals and water.

On the market, PU waterstop grouting materials are generally divided into two types:
Hydrophobic type (oil-based foaming)
Hydrophilic type (water-based non-foaming)

One-component oil-soluble polyurethane grouting material is produced by reacting complex polymerized polyol with polyisocyanate, resulting in a polymer

Water-based polyurethane grouting material is formed by reacting hydrophilic polyether polyol with isocyanate. When exposed to water, it undergoes a chemical reaction to create an elastic, gel-like consolidated body, achieving effective waterproof sealing. This type is a new high-pressure grouting material designed for waterproof plugging.

Eco-friendly Hydrophobic Polyurethane Grouting material

Polyurethane Foam Grouting material is a single-component hydrophobic polyurethane grout that is environmentally friendly.

The reaction between a combination of polyols and isocyanate yields this chemical grouting material, which is then end-capped with isocyanate.

The substance can foam up quickly when exposed to water, expanding in volume and becoming insoluble in water.

In addition to being waterproof, this material also has certain reinforcing and stabilizing properties.

It is frequently utilized in watertight leakage-plugging applications such as underground parking garages, sewer systems, water conservation and hydropower, and subway tunnels.

Features of the PU Waterstop Grouting

1. Chemical stability and good hydrophobicity.

2. With a wide permeation radius, a high volume-to-solidification ratio, and a rapid water reaction rate.When reacting with water, a significant amount of expansion pressure can be released, pushing the slurry deep into the crack to produce a stiff consolidation.

3. Effective resistance to chemical corrosion caused by acid, alkali, and organic solvents.

4. The coating is mold-free, smooth, and resistant to wear.

5. Excellent adhesion to a basis of concrete and other building materials.

6. You can change the viscosity and setting time to meet engineering specifications.

Application of the PU Waterstop Grouting

1. Filling seam sealing and applying a waterproof, anticorrosive coating to facilities such as water tanks, water towers, basements, and shelters;

2. Metal, concrete pipe layer, and steel structure corrosion protection;

3. Ground dustproofing measures and foundation reinforcement for buildings and tunnels beneath;

4. In construction projects, the strengthening and sealing of construction joints, deformation seams, and structural fissures;

5. Repairing leaks and reinforcing ports, wharves, piers, dams, hydroelectric facilities, etc.;

6. Water stop-gushing in the mine, wall protection and leak plugging in geological drilling, and selective water plugging in oil extraction, among other things.
