Proven & Trusted

Is your Building Showing Signs of Structural Cracking or Moisture Ingress through Cracks?

Bridgecrete’s crack injection solutions address structural and non-structural cracking across concrete, masonry and rendered building elements throughout Greater Sydney. With over 18 years of experience working alongside structural engineers and building consultants, our remedial teams diagnose the cause of cracking, select the appropriate injection system and deliver compliant repairs that restore the integrity of the affected element.

Structural cracks left untreated allow moisture and carbon dioxide to penetrate the concrete, accelerating the corrosion of internal steel reinforcement and leading to costly concrete cancer and spalling. Early intervention through crack injection is one of the most cost-effective ways to protect your asset and prevent minor defects from developing into major structural problems.

Epoxy Injection

Epoxy injection is used to restore structural integrity to cracks in concrete elements where monolithic behaviour needs to be reinstated. Bridgecrete's teams carry out low-pressure epoxy injection to structural cracks in beams, slabs, columns and walls, bonding crack faces together and preventing further movement, moisture ingress and reinforcement corrosion.

Polyurethane Injection

Polyurethane injection is used to seal active cracks and joints where water ingress is occurring. The expanding polyurethane reacts with moisture to form a flexible, waterproof seal that stops water flow through the crack. Bridgecrete uses polyurethane injection extensively in below-ground structures, basements and water-retaining elements.

Cementitious Grouting

For wider cracks and voids in concrete and masonry elements, cementitious grouting provides a cost-effective repair solution. Bridgecrete carries out cementitious grouting works across a range of building elements including retaining walls, masonry structures and concrete slabs where epoxy injection is not appropriate.

Structural Crack Monitoring

Before undertaking crack injection works, Bridgecrete's remedial teams assess and where required monitor structural cracks to determine whether movement is active or historic. This ensures the correct repair system is selected and that injection works are carried out at the right time to deliver a lasting outcome.

Crack Preparation & Surface Sealing

Correct preparation of cracks prior to injection is critical to the success of the repair. Bridgecrete's teams carry out all necessary crack preparation including routing, cleaning and surface sealing prior to injection to ensure full penetration of the injection resin and a complete, durable repair.

Post-Injection Reinstatement

Following crack injection, affected surfaces are reinstated to match the existing finish. Bridgecrete carries out all associated patching, rendering and coating works to restore the appearance of the repaired element and apply protective treatments that prevent future moisture ingress to the repaired area.
