Concrete cancer is a serious issue for many strata buildings in Sydney, and ATCO Projects is here to provide expert concrete cancer repair services. Over time, exposure to the elements, moisture, and age can cause concrete to degrade, leading to structural damage that compromises the safety and integrity of the building. At ATCO Projects, we specialise in repairing and restoring damaged concrete structures to their original strength, ensuring the long-term durability of your property.
Types of Concrete Damage We Repair
Concrete damage can take various forms, each requiring a unique repair approach. At ATCO Projects, we specialise in addressing the following types of concrete damage in strata buildings:
Cracking and Joint Separation
Concrete Spalling
Delamination and Discolouration
Our Concrete Repair Methods
At ATCO Projects, we use a range of methods to effectively repair damaged concrete, ensuring that the structural integrity of your property is restored. Our experienced team employs the latest techniques and materials to ensure that every repair is completed to the highest standards.
Surface Patching and Resurfacing
Surface patching and resurfacing are common methods for repairing concrete damage, particularly in cases of minor cracking, spalling, and surface wear. We carefully remove damaged areas and apply a high-quality patching compound or resurfacing material to restore the appearance and functionality of the surface. This method is ideal for smaller areas of damage, providing a smooth, durable finish that blends seamlessly with the surrounding concrete.
Crack Injection and Sealing
For more serious cracks or joint separations, we utilise crack injection and sealing techniques. This involves injecting a specialised resin into the cracks to fill voids and prevent further damage. The resin hardens, restoring the strength and stability of the concrete. We also apply high-quality sealants to ensure that the concrete remains protected from water infiltration and future damage. This method is highly effective for repairing structural cracks and preventing the spread of damage.
Steel Reinforcement and Recasting
In cases where the steel reinforcement inside the concrete has corroded, simply repairing the surface isn’t enough. We offer steel reinforcement and recasting services to restore the structural integrity of your concrete elements. This involves replacing or treating corroded steel, followed by recasting the concrete to restore its strength. Our team uses the highest-quality materials and follows all industry standards to ensure that the repair is permanent and effective.
Our Repair Process and Site Management
At ATCO Projects, we follow a streamlined, efficient process to ensure that all concrete cancer repairs are carried out with minimal disruption to your strata property. From inspection to completion, we manage every aspect of the repair, ensuring that the work is done to the highest standards of quality and safety.
Inspection and Condition Report
The first step in any concrete cancer repair project is a thorough inspection of the affected area. Our team will visit your property to assess the extent of the damage and identify any underlying issues. We provide a detailed condition report that outlines the damage, recommended repair methods, and a cost estimate. This ensures that you have a clear understanding of the work required before we begin.
Staging and Access Considerations
Concrete cancer repairs often require special staging and access arrangements, particularly in strata properties. We take great care in planning the logistics of the repair work, including determining the best access points and ensuring the safety of residents and workers. Our team works efficiently to minimise disruption to your property and ensure that repairs are completed in a timely manner.
Completion and Finishing
Once the repairs are complete, we conduct a thorough inspection to ensure that the work has been carried out to the highest standards. We also take steps to ensure that the repaired areas are properly finished, providing a seamless transition between the new and existing concrete surfaces. Our goal is to restore the integrity of your building while enhancing its appearance and ensuring long-term durability.

Signs of Concrete Damage
Concrete deterioration in strata buildings is often gradual but can escalate quickly if not addressed. Early identification allows for controlled remediation and reduces long-term costs.
Common signs include:
- Cracking or flaking of concrete surfaces
- Rust stains indicating corrosion of internal steel
- Bulging or delaminated concrete areas
- Exposed reinforcement bars
- Water ingress around slabs and balconies
These issues are typically linked to concrete spalling repair requirements, where moisture penetrates the concrete and causes steel reinforcement to corrode.
In strata environments, balcony slabs are particularly vulnerable. Ongoing exposure to weather and inadequate waterproofing often leads to strata balcony concrete repair works.
Where deterioration is present, it is important to assess related systems such as waterproofing and balustrading to ensure the full scope of works is addressed.
Our Repair Methods
ATCO Projects applies structured remediation methods based on the condition of the concrete and the extent of damage.
Surface Patching & Resurfacing
Surface-level damage can often be addressed through patching and resurfacing. This method restores the appearance and protects the underlying structure.
It involves:
- Removal of loose or damaged concrete
- Application of repair compounds
- Surface finishing to match existing conditions
Crack Injection & Sealing
Cracks can allow water to enter the structure, leading to further deterioration. Injection and sealing methods are used to restore integrity and prevent ongoing damage.
This process includes:
- Identifying active and dormant cracks
- Injecting suitable materials to fill voids
- Sealing surfaces to prevent moisture ingress
Steel Reinforcement & Recasting
Where corrosion has affected internal reinforcement, more extensive repairs are required.
This involves:
- Exposing and cleaning steel reinforcement
- Treating corrosion
- Recasting concrete to restore structural capacity
These methods are commonly applied in concrete cancer repair Sydney projects where structural performance must be reinstated.
Our Repair Process & Site Management
ATCO Projects follows a structured approach to ensure remediation works are delivered safely, efficiently, and in line with compliance requirements.
The process includes:
- Detailed condition assessment and scope definition

Frequently Asked Questions
What causes concrete cancer in Sydney buildings?
It typically occurs when water and oxygen reach the steel reinforcement, leading to corrosion and structural cracking—especially in coastal or high-moisture environments.
How long does concrete cancer repair take?
Most projects are completed within one to three weeks, depending on scale, accessibility, and damage severity.
Is remediation covered by strata or building insurance?
In most cases, structural repairs are covered under strata insurance, subject to policy conditions and engineering assessment.
What materials and coatings prevent future corrosion?
We use anti-corrosion coatings, high-strength repair mortars, and protective waterproof membranes to ensure long-term durability.
Will I receive certification after the repair is complete?
Yes. ATCO provides full documentation, compliance certification, and photographic records for all completed works.
What causes concrete cancer in strata buildings?
Concrete cancer is typically caused by moisture entering the concrete and corroding the steel reinforcement. This leads to expansion, cracking, and eventual spalling.
How urgent are concrete spalling repairs?
Concrete spalling should be addressed promptly. Delays can lead to further structural damage and increased repair costs.
Can repairs be staged across a building?
Yes. Works can be staged based on priority, access, and budget. A structured plan helps manage costs and minimise disruption.
Is concrete repair linked to waterproofing issues?
In many cases, yes. Failed waterproofing systems allow water to enter the structure, leading to corrosion and deterioration.
Do concrete repairs require strata approval?
Yes. As these works involve common property, approval from the owners’ corporation is typically required before works proceed.
