PU Foam Injection Grouting Services

PU Foam Injection Grouting Services

PU Foam Injection Grouting is one of the most effective waterproofing techniques used to stop active water leaks, seal cracks, prevent water seepage, and restore the integrity of concrete structures. This advanced waterproofing solution utilizes high-performance polyurethane resin that expands upon contact with water, creating a flexible, watertight seal within cracks, joints, and voids.

Our PU Injection Grouting services are widely used in residential, commercial, industrial, and infrastructure projects across the UAE to eliminate water ingress and provide long-term waterproof protection.

What is PU Foam Injection Grouting?

Polyurethane (PU) Foam Injection Grouting is a specialized waterproofing process where low-viscosity polyurethane resin is injected under pressure into cracks, construction joints, honeycombs, expansion joints, and leaking concrete structures.

When the resin comes into contact with water, it rapidly expands into a closed-cell foam, filling voids and sealing water pathways. This creates a permanent waterproof barrier that prevents further leakage and moisture penetration.

Benefits of PU Foam Injection Grouting

Stops Active Water Leaks

Effectively seals flowing and pressurized water leaks.

Expands to Fill Voids

Foam expansion allows complete filling of cracks, cavities, and hidden gaps.

Flexible Waterproof Seal

Maintains flexibility to accommodate structural movement.

Non-Destructive Repair

No need for major demolition or reconstruction.

Fast Leak Sealing Solution

Quick installation and immediate results.

Long-Term Waterproof Protection

Provides durable resistance against water infiltration.

Suitable for Wet Conditions

Can be applied even when water leakage is active.

Our PU Injection Grouting Process

1. Leak Inspection & Assessment

Our specialists identify:

• Water entry points
• Crack patterns
• Joint failures
• Structural defects

2. Surface Preparation

The affected area is cleaned and prepared for injection.

3. Injection Port Installation

Specialized injection packers are installed along cracks and leaking joints.

4. High-Pressure PU Injection

Polyurethane resin is injected under controlled pressure into the structure.

5. Foam Expansion & Leak Sealing

The resin reacts with water and expands to create a watertight seal.

6. Final Inspection & Finishing

After successful leak sealing:

• Packers are removed
• Injection holes are repaired
• Waterproofing performance is verified
