PU Injection Grouting in Pakistan | Polyurethane Injection Waterproofing | Unicorn Chemical PK

Professional PU Injection Grouting Services Across Pakistan

Water leaking through concrete cracks, construction joints, or underground walls can quickly damage a building’s structure if left untreated. In many cases, demolishing walls or floors isn’t necessary. PU Injection Grouting is an advanced waterproofing technique that seals active water leaks from inside the concrete by injecting polyurethane resin under high pressure.

Unicorn Chemical PK provides professional PU Injection Grouting Services in Pakistan, helping homeowners, builders, factories, and commercial property owners eliminate water seepage without major excavation or demolition. Our experienced technicians use specialized injection equipment and premium PU resins to permanently seal cracks and stop water ingress.

How PU Injection Grouting Works

Unlike surface waterproofing systems, PU injection grouting repairs the leakage at its source. Small injection packers are installed along the crack or leaking joint, and polyurethane resin is injected under pressure.

When the resin comes into contact with water, it expands rapidly and fills every void, crack, and capillary inside the concrete. This creates a flexible waterproof seal that prevents future water penetration while accommodating minor structural movement.

Where PU Injection Grouting is Used

Our PU Injection Grouting Process

• Leak Inspection — Our engineers identify the exact source of water ingress, crack width, and structural condition.
• Crack Preparation — Loose particles are removed, and injection ports (packers) are installed along the leaking crack or joint.
• High-Pressure PU Injection — Using professional injection pumps, polyurethane resin is injected until the crack is completely sealed.
• Packer Removal & Surface Finishing — After curing, injection packers are removed, and the repaired surface is finished for a clean appearance.
• Final Leak Testing — The repaired area is inspected to confirm that water seepage has been successfully eliminated.

PU Injection Grouting Price in Pakistan

The PU Injection Grouting Price in Pakistan depends on the crack size, leakage severity, resin consumption, accessibility, and total repair area.

• PU Injection Grouting: PKR 800–2,500 per injection point
• Crack Injection Repair: PKR 1,500–4,000 per running meter
• Basement Leak Injection: After Site Inspection
• Lift Pit PU Injection: Custom Quotation
• Industrial PU Grouting: Project-Based Pricing

Final pricing may vary depending on crack depth, water pressure, polyurethane resin consumption, and project complexity.

Frequently Asked Questions

What is PU Injection Grouting?

PU Injection Grouting is a waterproofing repair method in which polyurethane resin is injected into concrete cracks or joints to stop active water leakage.

Where is PU Injection Grouting used?

It is commonly used in basements, lift pits, foundations, tunnels, retaining walls, water tanks, underground parking areas, and concrete structures experiencing water seepage.

How much does PU Injection Grouting cost in Pakistan?

The cost generally starts from PKR 800 per injection point, but the final price depends on the number of cracks, resin usage, and project complexity.

Can PU Injection Grouting stop active water leakage?

Yes. It is specifically designed to stop active water leaks by expanding inside cracks and forming a flexible waterproof seal.

Is PU Injection Grouting better than cement grouting?

PU injection grouting is preferred for active water leakage because polyurethane expands and seals water pathways. Cement grouting is more suitable for structural void filling rather than stopping active leaks.

How long does PU Injection Grouting last?

When properly applied, PU injection grouting can provide 10–20 years or more of reliable waterproof performance, depending on structural conditions.

Does PU Injection Grouting require breaking the wall or floor?

No. In most cases, PU injection grouting repairs leakage without major demolition, making it a fast and cost-effective solution.

Do you provide PU Injection Grouting services across Pakistan?

Yes. Unicorn Chemical PK provides professional PU Injection Grouting services for residential, commercial, industrial, and infrastructure projects throughout Pakistan.
