Common Waterproofing Problems
Issues that Star Leak Proof PU effectively solves
Seepage from Negative Side
Water penetration from the opposite side of walls or slabs, particularly challenging to address with conventional methods.
RCC Cracks & Structural Leaks
Water leakage through cracks in reinforced concrete structures, basements, and underground facilities.
Membrane Failure
Breakdown of traditional waterproofing membranes leading to persistent leaks in critical areas.
Porous Concrete Issues
Water penetration through microcracks and porous concrete surfaces that are difficult to seal.
What is Star Leak Proof PU?
Advanced polyurethane injection solution for permanent waterproofing
PU-based Injectable, Expandable Waterproofing Solution
Star Leak Proof PU is a nano-based, low-viscosity, moisture-reactive polyurethane injection system specifically designed for sealing microcracks (<0.2 mm), voids, and porous concrete from the negative side with an expandable, chemically and corrosion resistant seal.
Key Features & USPs
What makes Star Leak Proof PU superior
Microcrack Penetration
Low viscosity formulation penetrates microcracks as small as 0.2 mm for comprehensive sealing.
Moisture-Reactive Expansion

Shop NowHow It Works
The application process of Star Leak Proof PU
Identify & Prepare
Conduct water ponding/thermal scan to identify leak sources. Clean surface and ensure it's free from contaminants.
Drill & Install
Drill ports at strategic locations and install G.I. nozzles for injection points.
Mix & Prepare
Mix components with slow drill to avoid air entrapment. Do not dilute the solution.
Inject
Inject manually or using mechanical pressure grouting equipment through installed nozzles.
Seal & Finish
Plug nozzles with mortar after injection. Clean tools immediately with water.
How to Apply
Proper application guidelines for optimal results
Surface Preparation
Surface must be clean and free from contaminants, dust, oil, or loose particles. Ensure proper identification of leak paths through testing.
Drilling Technique
Precise drilling at 45-degree angles to intersect cracks. Port spacing should be based on crack width and depth for optimal coverage.
Mixing Procedure
Mix components thoroughly with a slow-speed drill to avoid air entrapment. Do not dilute or add any foreign materials to the mixture.
Injection Method
Apply through manual or mechanical pressure grouting. Start from lowest point and move upward. Ensure complete filling of voids.
Safety Precautions
Use appropriate PPE including gloves, goggles, and masks. Ensure adequate ventilation during application. Avoid extreme weather conditions.
Post-Application
Plug nozzles with mortar after injection. Clean tools immediately with water. Allow proper curing time before subjecting to water pressure.
Where to Apply
Ideal applications for Star Leak Proof PU
Basements
Effective for negative side waterproofing in below-grade structures.
Retaining Walls
Seals leaks in earth-retaining structures exposed to water pressure.
Terraces
Waterproofing for terrace slabs and roof areas prone to leakage.
Water Tanks
Ideal for overhead and underground water storage tanks.
Swimming Pools
Effective sealing for pools and other water-containing structures.
Planter Boxes
Prevents water leakage from elevated garden and planter areas.
RCC Cracks
Specialized treatment for cracks in reinforced concrete structures.
Underground Structures
Waterproofing for tunnels, vaults, and other below-ground facilities.
