1. Product Overview

Polyurethane oil-based grouting liquid is a high-performance waterproof and sealing material designed for crack repair and leakage prevention. When injected into cracks or voids, it reacts with water to form a flexible yet durable waterproof barrier. This material is widely used for sealing cracks in concrete structures, underground engineering, tunnels, and basements.

2. Key Features

• Strong Water Reactivity: Expands upon contact with water to effectively seal cracks.

• High Adhesion: Bonds well with concrete, masonry, and other substrates.

• Excellent Waterproofing: Forms a flexible, non-shrinking waterproof barrier.

• Oil-Based Formulation: Provides superior durability and chemical resistance.

• Resistant to Harsh Environments: Withstands pressure, corrosion, and temperature variations.

• Efficient Injection Process: Easily injected into small cracks and voids.

3. Applications

• Crack repair in concrete structures, including bridges and dams.

• Waterproofing for underground tunnels, subways, and basements.

• Sealing of expansion joints and construction joints.

• Leakage prevention in reservoirs, water tanks, and sewage systems.

• Soil stabilization and foundation reinforcement.

4. Application Process

1. Surface Preparation: Identify cracks and clean the surface to remove dust and debris.

2. Drilling and Injection Port Installation: Drill holes and install injection ports at designated points.

3. Injection of Grouting Liquid: Use a high-pressure injection pump to inject the polyurethane grouting liquid into the cracks.

4. Reaction and Expansion: The liquid reacts with water and expands to fill voids completely.

5. Final Sealing and Inspection: Remove injection ports, seal the surface, and inspect for effectiveness.
