Floor/Slab Injection & Pressure Grouting Waterproofing

by AWEI – Ankit Waterproofing Engineers Inc.

At AWEI, we specialise in floor and slab waterproofing through advanced injection pressure grouting systems — a non-invasive, highly effective method to stop active leakages, seal cracks, and restore structural integrity from within.

This method is ideal for:

🏢 Basement floors & raft slabs

🏗️ Industrial RCC floors

🚗 Podium slabs & parking decks

💧 Slabs over water tanks or near seepage zones

🛠️ How It Works:

1. Diagnosis & Marking:

We identify cracks, cold joints, honeycombs, or voids where water ingress is occurring.

2. Drilling & Packer Installation:

Precision drilling is done around leakage paths, and injection packers are installed at proper angles.

3. Grout Injection Under Pressure:

Using high-pressure pumps, we inject PU (Polyurethane) or epoxy-based resins into the slab. These resins expand, seal, and bond within the crack structure.

4. Curing & Finishing:

Packers are removed post-curing and the surface is patched, leaving no visible damage.

🧪 Types of Grouts Used:

PU Grout: Expanding, flexible material ideal for active leaks and dynamic cracks

Epoxy Grout: Rigid and strong, used for structural stabilization of dormant cracks

Acrylic/Cementitious Grout: For sealing microcracks and damp zones

✅ Advantages of AWEI Grouting Systems:

Non-destructive solution (no breaking required)

Penetrates deep into cracks and voids

Strong bonding and long-term waterproofing

Fast application with minimal downtime

Compatible with both old and new concrete structures

Whether you're dealing with capillary seepage, leaking joints, or pressure water intrusion, AWEI’s injection pressure grouting system is a precision-engineered solution that delivers watertight, durable, and maintenance-free flooring.
