Our Polyurethane Concrete Repair Process
Site inspection & Free Consultation
Our team will visit your property to assess the extent of the cracks and discuss the best course of action. We’ll provide a transparent quote outlining the repair process and associated concrete cancer repair costs.
Crack Injection
Using polyurethane resin injection kit, we inject the high-strength resin deep into the crack, filling any voids and creating a watertight seal.
Surface Preparation
We meticulously clean the crack, test it for moisture content and carbonation depth and surrounding area to ensure optimal adhesion of the injected material.
Curing
The waterproofing resin membrane undergoes full polymerization, forming a durable, elastomeric bond within the crack substrate that effectively seals against moisture ingress, accommodates structural movement, and enhances long-term integrity of the repaired surface.
Steel Treatment or Replacement
Treating corroded steel is critical. Our expert technicians follow a structured process to repair or replace it based on damage severity.
Finishing Touches
Depending on the location and size of the crack, we may recommend cosmetic finishing touches to restore the appearance of the concrete surface.

Testimonials
“We had water coming through a crack in our basement wall every time there was heavy rain. The team used polyurethane injection waterproofing to seal the crack, and we haven’t had a leak since. Quick, tidy and professional job.”
Daniel M. — Southport, Gold Coast
“I’d tried a couple of temporary fixes, but the leak kept coming back. They recommended polyurethane resin injection and explained how it would stop the water ingress through the concrete. The repair worked perfectly.”
Michael R. — Robina, Gold Coast
“Very impressed with the polyurethane injection foam waterproofing. They found where the water was getting through, sealed the concrete cracks properly and left the area clean afterwards. We’ve had plenty of rain since with no more leaking.”
Jason T. — Coomera, Gold Coast
“Water was getting through a concrete joint during heavy Brisbane rain. The team injected and sealed the affected area with polyurethane, and it’s stayed dry since. I’d happily recommend this polyurethane injection contractor.”
Andrew C. — Carindale, Brisbane
“We had a persistent leak through a concrete wall. The polyurethane foam injection system was completed without having to pull everything apart or excavate outside. Straightforward service and a great result.”
Mark P. — Loganholme, Brisbane
“Really happy with the waterproofing work. Water was finding its way through a concrete joint, and previous patch repairs hadn’t lasted. The polyurethane crack repair has done the job, even after some solid rain.”
Matt K. — Mount Gravatt, Brisbane

Frequently Asked Question
How long does the Polyurethane crack injection repair take?
Most Polyurethane Injection for Concrete Crack Repair can be completed in a few hours, depending on the size and number of cracks. The resin cures quickly, allowing for minimal downtime.
Is concrete polyurethane injection system a permanent solution for Brisbane or Gold Coast's concrete leak problem?
Yes—when applied correctly, high-pressure polyurethane foam injections provide a long‑lasting seal that adapts to structural movement. However, their longevity also depends on the condition of the structure and the surrounding environment.
What types of cracks can be repaired with polyurethane injection system?
It’s ideal for repairing leaking, non-structural cracks in concrete walls, foundations, basements, tunnels, and retaining walls. It’s especially effective in wet or damp environments.
What is polyurethane injection crack repair?
Polyurethane injection crack repair is a method used to seal leaking cracks, joints and voids in concrete. A liquid polyurethane resin is injected into the crack under controlled pressure through installed injection packers.
When the resin contacts moisture, it reacts, expands and forms a flexible foam or seal inside the crack. This blocks water pathways and helps prevent further water ingress.
It is commonly used for:
- Basements and retaining walls
- Lift pits and underground car parks
- Concrete walls and floor slabs
- Tunnels and foundations
- Construction joints
- Cracks affected by active water leaks
Polyurethane injection crack repair is mainly a waterproofing and leak-sealing method. It should not automatically be described as a structural strengthening repair. When a crack requires structural bonding, epoxy injection is generally the more appropriate solution.
When should I hire a polyurethane injection contractor instead of a DIY fix?
Contractors have the industrial-grade equipment, chemical expertise, and diagnostic skills to determine whether polyurethane (for flexible, waterproof sealing) or structural epoxy (for load-bearing cracks) is required.
Is polyurethane safe for indoor use?
Can high-pressure polyurethane foam injections be used for structural repairs?
No. Polyurethane foam injection for concrete crack repair is designed for waterproofing, not structural reinforcement. For structural cracks, epoxy injection is more appropriate.
How much does polyurethane injection foundation repair cost?
Costs vary based on crack size, location, and accessibility. Typical injection pricing ranges from $300 to $1,500+ per polyurethane injection crack repair, depending on scope.
Do I need a licensed waterproofing contractor for polyurethane crack injection in Gold Coast or Brisbane?
Yes, in Queensland, you do need a licensed waterproofing contractor for concrete injection work—especially when it’s part of a waterproofing system.
🛠️ Why Licensing Matters
- Compliance with Australian Standards: Waterproofing work must meet standards like AS 3740-1994, which governs waterproofing in wet areas.
- Building Code Requirements: Waterproofing is considered a regulated building activity under the Queensland Building and Construction Commission (QBCC).
- Insurance and Warranty: Licensed contractors typically offer workmanship guarantees and are insured, which protects you if something goes wrong.
