Why Choose Polyurethane
Injection Repairs
Polyurethane injection is a proven method for sealing active and dormant leaks. The resin expands upon contact with moisture, creating a flexible, watertight seal deep within the crack. This noninvasive process allows for quick application with minimal disruption, ideal for residential, commercial, and industrial settings.
Why Polyurethane Injection Is the Smart Solution
for Concrete Cracks?
- Water-Activated Expansion: Reacts with moisture to expand and fill even the smallest voids.
- Flexible & Durable: Accommodates future crack movement without compromising the seal.
- Non-Invasive Application: No need for excavation or major structural disruption.
- Fast Cure Time: Quick turnaround with minimal downtime.

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 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.

Frequently Asked Question
How long does the process take?
Most repairs can be completed in a few hours, depending on the size and number of cracks. The resin cures quickly, allowing for minimal downtime.
Is polyurethane injection a permanent solution?
Yes—when applied correctly, polyurethane injection offers a long-lasting seal that adapts to structural movement. However, the longevity also depends on the condition of the structure and surrounding environment.
What types of cracks can be repaired with polyurethane injection?
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.
Is polyurethane safe for indoor use?
Can it be used for structural repairs?
No. Polyurethane injection is designed for waterproofing, not structural reinforcement. For structural cracks, epoxy injection is more appropriate.
How much does polyurethane injection cost?
Costs vary based on crack size, location, and accessibility. Typical 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 Queensland?
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.
