Overview

PU grouting is a fast-expanding, water-reactive injection technique used to seal cracks, prevent leaks, and stabilize structures. It is commonly used in basements, tunnels, and water tanks, where preventing water infiltration is critical.

Unlike cementitious grouting, PU grouting expands upon contact with water, allowing it to seal even the smallest cracks with high efficiency.

Best for:

✔ Basements & Underground Structures – Prevents groundwater infiltration.
✔ Tunnels, Dams & Water Tanks – Seals cracks and prevents leakage.
✔ Industrial & Commercial Buildings – Stops water penetration and strengthens structures.
✔ Soil & Rock Stabilization – Prevents ground movement.

How it Works:

1️⃣ Drilling Injection Ports – Creating access points for grout application.
2️⃣ PU Resin Injection – Expanding material fills cracks and voids.
3️⃣ Foaming & Sealing – PU reacts with moisture and expands.
4️⃣ Final Inspection & Strength Testing – Ensuring complete waterproofing and stability.

Benefits:

✅ Stops Water Leaks Instantly – Expanding foam fills gaps completely.
✅ High Bonding & Crack Sealing Strength – Prevents further deterioration.
✅ Resistant to Chemicals & Corrosion – Long-lasting protection.
✅ Can Be Applied in Wet Environments – Ideal for water-prone structures.
