PU Injection Waterproofing
Star Leak Proof
Polyurethane Injection for Negative-Side Waterproofing
Star Leak Proof is a polyurethane (PU) foam injection system for negative-side waterproofing, developed by Starshieldpaints. It seals even the tiniest cracks and voids in concrete structures, preventing water penetration and structural damage with a long-lasting waterproofing solution.
Easy to use, with accurate measurement for precise calculations that reduce wastage, Star Leak Proof offers rapid expansion and curing, strong adhesion and compatibility with membranes. It is tailored to the substrate, severity of leakage and environmental conditions of each project.
Key Benefits of Star Leak Proof PU Injection
- Excellent leak sealing of the smallest cracks and gaps
- Long-term protection against water damage
- Works on concrete, masonry and brickwork
- Quick and easy application
- Rapid expansion and curing, strong adhesion
- Compatible with membranes
- Cost-effective by preventing repairs

The Problem
Is Water Leaking Into Your Structure?
Below-grade structures need a system that seals leaks at the source, from the negative side, without major demolition.
Leaks from the Negative Side
Water pushes through cracks and voids in basements, tunnels and foundations from the outside, where it cannot be coated.
Structural Damage
Continuous water penetration weakens concrete over time and leads to expensive structural repairs.
Costly, Repeated Repairs
Surface patches fail when the leak source is not sealed, leading to repeated rework, wastage and downtime.
Benefits
6 Key Benefits of Star Leak Proof
Star Leak Proof is a two-component polyurethane foam injection system that expands, fills gaps and cures quickly, forming a durable and flexible barrier against water ingress. It is suited to basements, tunnels, foundations, underground structures, swimming pools and water tanks.
Excellent Leak Sealing
Superior leak sealing ensures even the smallest cracks and gaps are effectively sealed, preventing water ingress.
Long-Term Protection
This PU injection provides long-term protection against water damage, ensuring the durability and integrity of the structure.
Many Substrates
Can be applied to concrete, masonry and brickwork, making it suitable for a wide range of applications.
Quick and Easy Injection
A relatively simple and efficient injection process saves time and labor cost during waterproofing.
Accurate Measurement
Accurate measurement makes it easy to determine the required quantity, eliminating wastage and saving money.
Saves Money Long-Term
By preventing water damage and subsequent repairs, Star Leak Proof helps save money in the long run.
How to Apply
How to Apply Star Leak Proof in 3 Steps
Wear appropriate protective gear and ensure proper ventilation. Follow the safety guidelines supplied with the product.
Surface Preparation & Ports
Clean the surface thoroughly, removing any loose particles, dirt or contaminants. Install injection ports at regular intervals along the cracks or joints.
Mixing & Injection
Mix the Star Leak Proof solution as per the manufacturer instructions. Inject the solution into the prepared ports, starting from the lowest point and working upwards.
Curing & Finishing
Allow the injected solution to cure for the recommended time. Once cured, remove the injection ports and repair any visible cracks or imperfections.
FAQs
Frequently Asked Questions
Everything about Star Leak Proof, the PU injection system for negative-side waterproofing and crack sealing.
What is Star Leak Proof?
Star Leak Proof is a polyurethane injection system for negative-side waterproofing, used to prevent water ingress and leakage in below-grade structures such as basements, tunnels and foundations.
How does Star Leak Proof work?
The PU injection system consists of two components that are mixed and injected into cracks and voids using a specialized pump. The polyurethane foam expands, fills the gaps and cures quickly, forming a durable and flexible barrier against water penetration.
What are the advantages of Star Leak Proof?
Easy application, fast curing, high expansion for comprehensive coverage, good adhesion to various substrates and compatibility with membranes for enhanced protection.
What surfaces can Star Leak Proof be used on?
It adheres well to concrete, masonry and other porous substrates commonly found in below-grade structures.
Can Star Leak Proof be used with other waterproofing systems?
Yes, it is compatible with membranes and can be used with other waterproofing systems for enhanced protection against water ingress.
How is Star Leak Proof applied?
The process involves surface preparation, identifying cracks or voids, installing injection ports and injecting the polyurethane foam using a specialized pump, starting from the lowest point and working upwards.
Are there safety precautions during application?
Yes. Wear appropriate personal protective equipment (PPE) and ensure proper ventilation in the work area, and follow the guidelines supplied with the product.
