PU Injection Grouting in Multan | Polyurethane Injection Waterproofing Experts | Unicorn Chemical

Professional PU Injection Grouting Services in Multan

Water leakage through concrete cracks, basement walls, lift pits, retaining walls, underground structures, and construction joints can cause serious structural damage if not repaired promptly. Surface waterproof coatings alone are often insufficient to stop active water leaks because the water continues to travel through internal cracks and voids.

Unicorn Chemical provides professional PU Injection Grouting Services in Multan using advanced polyurethane (PU) injection technology to permanently stop active water leakage. Our experienced waterproofing specialists inject premium polyurethane resin into concrete cracks, joints, and voids where it expands and forms a flexible, watertight seal.

Whether you have leakage in a basement, lift pit, retaining wall, foundation, underground parking, water tank, or RCC structure, we deliver reliable PU injection grouting solutions across Multan.

What is PU Injection Grouting?

PU Injection Grouting (Polyurethane Injection Grouting) is a specialized waterproofing technique used to stop active water leakage in concrete structures. A low-viscosity polyurethane resin is injected under pressure into cracks, construction joints, and voids. When the resin comes into contact with water, it expands, fills the gaps, and creates a durable waterproof barrier.

This method is one of the most effective solutions for sealing active leaks without breaking or demolishing the existing structure.

Frequently Asked Questions

What is PU Injection Grouting?

PU Injection Grouting is a waterproofing method where polyurethane resin is injected into leaking concrete cracks and joints to stop active water leakage and create a flexible waterproof seal.

What does PU stand for?

PU stands for Polyurethane, a waterproof resin that expands inside cracks and seals water pathways permanently.

Where is PU Injection Grouting used?

PU injection grouting is commonly used in basements, lift pits, retaining walls, water tanks, underground parking areas, expansion joints, RCC structures, and foundation walls.

How much does PU Injection Grouting cost in Multan?

PU Injection Grouting generally starts from Rs. 450 per running foot. The final cost depends on crack size, leakage severity, resin quantity, and project conditions.

Is PU Injection Grouting better than surface waterproofing?

For active water leakage through concrete cracks, PU injection grouting is usually more effective because it seals the leak from inside the structure rather than only covering the surface.

Can PU Injection permanently stop water leakage?

Yes. When applied correctly by experienced professionals using high-quality polyurethane resin, PU injection grouting provides long-lasting protection against active water leakage.

Do you provide free site inspections in Multan?

Yes. We offer FREE site inspections in Multan to assess leakage problems and recommend the most effective PU injection waterproofing solution.
