JISHAN REPAIR A-307 HYDROPHILIC POLYURETHANE LEAK STOPPER GROUTING
✔ Pu grouting ✔ Pu foam ✔ Pu injection
- Upgraded formula
- Imported material
- Ingenious manufacturing
This low-viscosity grouting with a high solid content is produced through a polymerization reaction between polycyanate and single-component, multi-hydroxyl polyethers. When it comes into contact with water, it can self-emulsify and quickly form an impermeable, highly elastic get that offers both elastic water-stopping and water-sealing performance.

Description
Scope of Application
This product is used for water stopping in long-term aquatic environments, for seepage prevention in non-structural cracks with deformation, and for rapid sealing of leak (infiltration) points in concrete, rock, soil, and other materials.
Features
- Excellent hydrophilicity allows for quick gel solidification upon contact with water, providing rapid water-stopping capabilities.
- The solidified material is an elastomer, boasting excellent elasticity, no shrinkage, and outstanding resistance to settlement deformation.
- The product boasts excellent water resistance, making it ideal for quickly sealing leaks in water flow. It adheres strongly to the substrate and demonstrates a high level of adaptability to different water qualities.
- The solidified material is resistant to most organic solvents, weak acids, bases, and organic microorganisms.
Key Points for Application
- Inspect the leak site and clean up any debris at the leak site. After confirming the leak point, drill holes and install injection packers. The hole spacing is typically 10 cm to 30 cm apart.
- Use a high-pressure grouting machine to inject the product through injection packers. Move on to the next hole and continue the injection when the slurry comes out from the adjacent hole.
- After the first grouting is completed, repeat the process starting from the first packer. Complete the grouting under the designated pressure, typically at a grouting pressure of 0.3 MPa and an injection rate of ≤ 0.01 L/min.
- After 72 hours, check the leak site for any signs of water leakage. If there is no water leakage, remove the exposed packers, seal and level the surface with mortar.
Precautions
- Since this product is made of polyurethane, the application should be done in a well-ventilated area away from any source of fire. Operators should wear protective goggles. In case of accidental splashing into the eyes, rinse with plenty of clean water and seek medical attention immediately.
- Once opened, this product should be used up as soon as possible. Any remaining materials must be disposed of according to regulations and should not be directly poured into drains, water, or soil.
