Effective remedial crack repairs by Waterstop Solutions NSW Specialist team.


Structural concrete crack repair with epoxy injections by Waterstop Solutions NSW.


We help restore the structural integrity of concrete by injecting high-quality liquid epoxy resin into defects in the concrete structure. We repair everything from basic hairline fractures in concrete right through to more serious structural damage. We specialise in concrete crack injection for structural crack repair and dynamic crack repair.


Cracks in concrete structures can be a cause for concern, but they can be effectively repaired with the right knowledge and proper remedial concrete crack injection repair techniques.

The key to successful crack repair is understanding the cause and nature of the crack and whether the crack is dormant or active. The object of any repair is to improve the durability and wear of a surface, reduce its permeability and prevent the development of a corrosive environment for the reinforcement steel. The goal is to ensure that the long-term integrity of the concrete elements is not compromised.


To Reinforce Structural Integrity:


When it comes to repairable structural cracks where concrete strength is of utmost importance, epoxy resins play a vital role. Injecting concrete cracks with engineer-specified methods and materials tailored to the specific crack’s characteristics ensures a reliable repair that addresses the underlying issue. The repaired structure gains strength and regains its load-bearing capacity. This reinforcement not only fixes the immediate issue but also prevents future damage and prolongs the life of the concrete structure.

The Waterstop Solutions team specialises in this process, employing engineer-specified methods and materials tailored to the specific crack characteristics. This approach ensures a reliable and durable repair that addresses the underlying issues while preventing further deterioration.

With an impressive track record of successfully completing thousands of projects in QLD and NSW, our teams have acquired extensive expertise and demonstrated the effectiveness of their injection techniques.


Epoxy resin products are specifically formulated for this application, offering physical properties higher than that of concrete.  Injection epoxy resins are required to have low viscosity so they can be injected into tight cracks.

Premium epoxy resins are moisture insensitive (will bond to wet concrete) and can have curing properties from semi rigid through to flexible.

Our delivery systems for epoxy injection include low-pressure syringes, balloons, gravity, dual caulking-gun systems and high-pressure injection (similar to the polyurethane injection system).

Waterstop Solutions’ extensive range of resins and our raft of delivery systems have successfully tackled every scenario that we have encountered to date – from under bridges, to under water on dam walls.
