1. Product Overview

Hydrophilic grouting material is a water-reactive polyurethane or acrylic-based injection material designed for effective sealing and waterproofing of cracks, joints, and voids in concrete structures. Upon contact with water, it expands and forms a flexible, waterproof gel or foam that tightly seals leaks and prevents further water ingress. This material is widely used in underground construction, tunnels, basements, and other water-sensitive areas.

2. Key Features

• Water-Activated Expansion: Reacts with water to expand and fill cracks completely.

• High Flexibility: Forms an elastic and durable waterproofing seal that adapts to structural movements.

• Strong Adhesion: Bonds effectively with concrete and other porous materials.

• Excellent Water Resistance: Provides a long-lasting barrier against water penetration.

• Fast Reaction Time: Quickly reacts with water for rapid sealing of leaks.

• Non-Toxic & Eco-Friendly: Safe for use in potable water structures and environmentally friendly applications.

3. Applications

• Sealing of cracks, joints, and voids in concrete structures.

• Waterproofing for tunnels, basements, and underground parking garages.

• Repair of leaking expansion joints and pipe penetrations.

• Structural waterproofing for dams, reservoirs, and water treatment plants.

• Prevention of water seepage in subways and underground facilities.

4. Installation Process

1. Surface Preparation: Clean the crack or void to remove dust, debris, and loose materials.

2. Drilling Injection Ports: Drill holes at strategic points along the crack for injection.

3. Injection Process: Use a high-pressure pump to inject the hydrophilic grout into the crack.

4. Reaction & Expansion: The material reacts with water and expands to seal the void completely.

5. Final Inspection: Check the sealed area to ensure complete waterproofing and structural integrity.
