Areas of Application
Waterproofing Injection Treatment
Star Leak Proof PU
High-Performance Waterproofing Injection Treatment
Star Leak Proof PU is a nano-based polyurethane waterproofing injection treatment built for structures fighting water pressure from the negative side. Contractors and facility owners choose this injection grouting waterproofing system to seal basements, tanks, tunnels, and below-grade walls where leaks rarely stop on their own.
The low-viscosity compound penetrates deep into cracks and voids, then expands on contact with moisture inside concrete pores, closing shrinkage cracks from within. Unlike surface coatings, it builds strength into the concrete itself, giving structures lasting protection against seepage.
6 Ways Star Leak Proof PU Solves Real Waterproofing Problems
- Nano-based polyurethane formula that penetrates deep into micro-cracks and voids
- Low-viscosity injection grouting waterproofing action that reaches fractures other sealants can't
- Moisture-triggered expansion that closes shrinkage cracks from inside concrete pores
- Rapid strength gain, giving treated concrete mechanical properties beyond premium concrete
- A flexible, durable barrier that resists cracking under structural movement
- Negative-side application that stops leaks without excavation or exterior digging

The Problem
Problems Requiring Waterproofing Injection Treatment
Seepage through cracks, internal shrinkage cracking, and hard-to-reach negative-side leaks all call for an injection-based fix. Star Leak Proof PU is built to solve all three.
Water Seepage Through Cracks
Hairline cracks and voids in concrete allow water to penetrate into basements, tanks, and underground structures.
Shrinkage Cracks in Concrete
During curing, concrete develops internal cracks that weaken the structure and create leakage paths.
Negative Side Leakage Issues
Water entering from the inaccessible side of structures makes external waterproofing difficult, requiring injection-based repair solutions.
Benefits
6 Ways Star Leak Proof PU Solves Real Waterproofing Problems
Star Leak Proof PU is a nano-based polyurethane injection waterproofing system designed to stop water leakage from the negative side, penetrating deep into cracks and concrete pores and expanding on contact with moisture to seal leaks from within.
Deep Crack Penetration Stops Leaks at the Source
Because Star Leak Proof PU has low viscosity, this waterproofing injection treatment travels into micro-cracks and voids that thicker sealants miss, sealing the leak path fully instead of masking it on the surface.
Faster Project Turnaround With Rapid Strength Gain
This injection grouting waterproofing system gains mechanical strength several times faster than premium concrete, so contractors move to the next task sooner without compromising the repair's integrity.
Long-Term Flexibility Prevents Repeat Cracking
Star Leak Proof PU cures into a flexible barrier that moves with the concrete, so the waterproofing injection treatment keeps sealing the crack instead of failing under normal movement.
Moisture-Activated Expansion Creates a Complete Seal
This formula expands the moment it contacts moisture inside concrete pores, filling voids from within and helping the surrounding concrete reach a fully sealed, watertight, crack-resistant condition.
No Excavation Needed for Negative-Side Repairs
Because this injection waterproofing treatment applies from the negative side, teams stop active leaks in basements and below-grade walls without excavation, saving time and cost.
Dependable Injection Grouting Waterproofing for Critical Structures
Water tanks, swimming pools, and terrace gardens face constant water exposure. Star Leak Proof PU bonds chemically, anchors mechanically, and expands to form a compression seal, keeping critical structures dry for years.
How to Apply
Application Method
Applying Star Leak Proof PU is straightforward
Surface Preparation
Conduct a water ponding test or thermal imaging survey to identify and mark leakage points. Drill small grooves on the negative side of the structure to install GI nozzles at suitable intervals for pressure grouting.
Mixing
Shake Star Leak Proof PU thoroughly until homogeneous, then transfer it into a mixing container. Mix for at least 2 minutes using a slow-speed stirrer (300–400 RPM) to achieve a uniform consistency.
Application
Fix GI nozzles at the identified leakage points and pressure grout the mixed Star Leak Proof PU manually or mechanically. Keep polymer-modified mortar ready to seal the nozzle tips during grouting.

What Our Customers Say
FAQs
Frequently Asked Questions
Everything you need to know about Star Leak Proof PU.
What is a waterproofing injection treatment?
A waterproofing injection treatment is a repair method that injects expanding polyurethane into cracks, joints, or voids in concrete to stop water flow. It seals structures from within instead of relying on a surface coating alone.
How does Star Leak Proof PU work as an injection grouting waterproofing system?
It penetrates deep into cracks due to its low viscosity, then reacts with moisture in the concrete to expand and form a chemical bond, mechanical anchor, and compression seal.
Where can this waterproofing injection treatment be used?
This waterproofing injection treatment is designed for basements, water tanks, swimming pools, tunnels, terrace gardens, retaining walls, and other RCC structures facing continuous water exposure or leakage.
Is this injection waterproofing treatment suitable for active leaks?
Yes. This injection waterproofing treatment is specifically formulated for severe, active leaks, expanding immediately on contact with moisture to stop water flow at the source.
How long does the waterproofing injection treatment take to cure?
Star Leak Proof PU gains strength rapidly and typically cures within 24 to 48 hours at room temperature, after which the injection packers can be safely removed.
Can this waterproofing injection treatment be applied from the inside of a building?
Yes. It is formulated for negative-side application, meaning this waterproofing injection treatment stops leaks from the interior without excavating the exterior side of the wall.
What is the difference between epoxy injection and this waterproofing injection treatment?
Epoxy injection is rigid and works best on dry, structural cracks, while this waterproofing injection treatment is flexible and reacts with water, making it better suited to active leaks and moving joints.
Does the waterproofing injection treatment prevent future cracking?
Yes. By curing into a flexible, elastomeric seal, this waterproofing injection treatment moves with the concrete and helps prevent shrinkage cracks from reopening over time.
Is professional application required for this injection grouting waterproofing system?
Professional application is recommended. Installing packers, mixing ratios, and injection pressure all affect results, so trained applicators get the most out of this system.
Why choose Star Leak Proof PU over other waterproofing injection treatment options?
Star Leak Proof PU combines deep penetration, rapid strength gain, and long-lasting flexibility in one waterproofing injection treatment, making it a dependable choice for critical below-grade structures.
