Concrete Repair
Engineering-Led Concrete Repair for Critical Infrastructure
Ironstone Civil delivers specialised concrete repair solutions designed to restore, protect and extend the life of reinforced concrete infrastructure. As experienced concrete repair contractors, we approach every project with a focus on engineering accuracy, material suitability and proven construction methodologies. Our goal is to address deterioration at its root cause and ensure long-term structural performance — not just superficial improvement.
Reinforced concrete structures are durable but exposure to environmental conditions, operational loads, poor construction, water ingress, chemical attack and ageing can significantly reduce their service life. When deterioration is left unaddressed, issues such as cracking, reinforcing steel corrosion and concrete spalling can compromise safety and performance.
Ironstone Civil provides practical, technically sound concrete remediation solutions that help asset owners manage risk and preserve their infrastructure for decades to come.
Understanding Concrete Deterioration
Concrete deterioration often begins unnoticed. Minor cracks, early signs of corrosion or localised leaks can progress rapidly under the right conditions. The most common drivers of deterioration include:
• Carbonation of concrete reducing the alkalinity needed to protect reinforcement
• Chloride ingress leading to reinforcement corrosion
• Water penetration causing cracking, spalling and internal damage
• Structural movement from settlement, vibration or overloading
• Chemical attack from wastewater, industrial fluids or aggressive soils
• Freeze-thaw cycles in exposed environments
• Construction defects such as inadequate cover or poor compaction
Over time, these issues can lead to significant structural loss, safety risks or the need for major rehabilitation. Effective reinforced concrete repair requires the correct diagnosis, targeted methodology and the selection of materials compatible with the existing structure.
Our Concrete Repair Contractor Services
Comprehensive Reinforced Concrete Repair
We provide a full suite of concrete repairs for deteriorated, damaged or ageing structures. Our capabilities include:
• Spalling and delamination repair
• Concrete breakout and reinstatement
• Removal of chloride-contaminated concrete
• Application of high-performance repair mortars
• Structural strengthening works
• Coatings and protective systems to improve durability
Our approach ensures the reinstated concrete is compatible in strength, durability and performance with the existing structure. All repairs follow strict procedures to ensure long-term stability.
Concrete Crack Injection
Cracks are one of the earliest and most visible signs of deterioration. Left untreated, they can allow water and chlorides to penetrate the structure, accelerating reinforcement corrosion and weakening the element.
Ironstone Civil provides expert concrete crack injection services, including epoxy crack injection for structural cracks and polyurethane injection for active leaks or non-structural openings. Epoxy injection bonds cracked concrete back together, restoring monolithic strength, while flexible polyurethanes seal against water ingress.
As experienced concrete crack injection contractors, we assess the cause, extent and movement characteristics of each crack before selecting the most appropriate material. Proper preparation, injection sequencing and pressure control are essential for reliable results. Our team has extensive experience performing crack injection in tunnels, culverts, slabs, retaining walls, bridge elements, water infrastructure and industrial facilities.
Cathodic Protection and Corrosion Mitigation
Corrosion of reinforcement is a major cause of concrete deterioration. Ironstone Civil offers corrosion control solutions that slow, stop or prevent corrosion activity. These include:
• Patch and protective coatings
• Corrosion inhibitors
• Increase of concrete cover through repair
• Targeted anode systems in high-risk areas
By implementing appropriate corrosion mitigation measures, we help extend the service life of reinforced concrete in harsh or aggressive environments.
Water Stopping and Leakage Control
Water ingress is one of the most damaging forces acting on concrete. Our water stopping services complement our repair methods by addressing leaks that threaten concrete durability and reinforcement health. We deliver:
• Polyurethane and acrylic resin injection
• Leak sealing in shafts, tunnels and culverts
• Repair of joints, penetrations and cold joints
• Installation of waterproofing membranes or barriers
Preventing moisture movement is essential for the long-term success of any concrete remediation program.
Our Expertise Across Sectors
Ironstone Civil’s concrete repair capabilities are applied across:
• Mining and resources infrastructure
• Road and rail assets
• Water and wastewater structures
• Industrial facilities
• Tunnels, culverts and confined-space structures
