Description

PU Grouting Service in Chennai – Professional Leakage & Crack Repair

PU Grouting, also known as Polyurethane Injection Grouting, is an advanced waterproofing method used to seal cracks and stop water leakage in concrete structures. Sara Waterproofing provides expert PU grouting services in Anna Nagar & all areas of Chennai for both residential and commercial buildings.

What is PU Grouting?

PU Grouting is a high-pressure injection system where polyurethane resin is injected into cracks, joints, or gaps. The PU chemical expands rapidly when it comes in contact with water, forming a strong, flexible, and permanent waterproof seal inside the crack.

This makes it one of the most effective methods for stopping active water leakage.

Where PU Grouting is Used

PU Grouting is suitable for:

• Bathroom leakage

• Wall dampness & seepage

• Overhead tank crack repair

• Sump & underground tank leakage

• Basement & foundation waterproofing

• Lift pit waterproofing

• Terrace slab cracks

• Concrete joints & expansion joints

• Swimming pool leak repair

How PU Grouting Works

1. Crack identification and cleaning

2. Drilling injection points along the crack

3. High-pressure injection of PU resin

4. PU expands 10–20 times to fill the crack

5. Water path is fully blocked

6. Final sealing and waterproofing inspection

This process gives quick and long-lasting results without breaking the structure.
