Structural defects are among the most critical issues in any building, because they directly affect safety, compliance, and long-term performance. Left unchecked, they can result in catastrophic failures, significant liability, and costly emergency works. These defects can be caused by original construction errors, material degradation, design flaws, water ingress, or overloading.
At Atomic Projects, our approach to structural defect repairs combines forensic-level investigation with engineer-certified solutions.
1. Investigation & Diagnosis
We begin with a detailed structural survey, often working alongside remedial engineers. This includes:
- Non-destructive testing (NDT) such as ground-penetrating radar, ultrasonic pulse velocity, or rebar scanning to map reinforcement and detect voids.
- Crack monitoring and deflection measurements to assess movement.
- Material sampling for compressive strength and carbonation testing.
2. Engineering the Solution
Based on the defect’s cause and severity, we prepare a remedial strategy, which may include:
- Concrete Beam or Slab Strengthening using carbon fibre reinforcement or steel plate bonding.
- Column Jacketing for increased load capacity or corrosion protection.
- Load Redistribution through the introduction of new support members.
- Footing Underpinning where foundation settlement is contributing to instability.
3. Precision Execution
Our site teams execute the works with the same discipline used in Tier 1 construction environments:
- Controlled demolition of damaged elements.
- Installation of reinforcement systems as per engineering specifications.
- High-strength repair mortars or epoxy bonding agents for structural reinstatement.
- Corrosion mitigation treatments to prevent future degradation.
4. Compliance & Verification
All works are verified through on-site inspections, testing, and certification by a registered structural engineer. Final reports are issued for record-keeping and insurance purposes.
By combining technical accuracy, specialist equipment, and multi-trade integration, our structural defect repair process restores a building’s integrity while minimising disruption to occupants.
Frequently Asked Questions
What qualifies as a structural defect?
Under the Home Building Act 1989 (NSW), a major defect in a structural element is one that affects the structural performance of the building or could cause the collapse or failure of a structural element. This includes issues with slabs, columns, beams, load-bearing walls, and footings. Structural defects carry a 6-year statutory warranty in NSW.
Do I need a structural engineer involved?
For significant structural defects, yes — and we coordinate this as part of our service. Atomic Projects works alongside structural engineers to confirm the extent of damage, design the repair methodology, and verify the completed works meet engineering requirements. All structural repairs are documented and signed off by the relevant engineer.
Can structural cracks be permanently repaired, or will they return?
Whether a repair is permanent depends on addressing the root cause. If the cracking is due to ongoing settlement, reactive soils, or live structural movement, the repair strategy must account for that movement (e.g., using flexible sealants or crack-stitching reinforcement). Our diagnosis phase identifies the cause so the repair strategy is appropriate.
How disruptive is structural defect repair work?
Disruption depends heavily on scope and access requirements. Localised concrete spalling repairs, for example, involve short-term scaffold or swing-stage access with minimal resident impact. Full slab or column repairs may require temporary propping and controlled access zones. We plan works to minimise disruption and communicate clearly with strata managers and residents.
What Australian Standards govern structural defect repairs?
Structural concrete repairs typically reference AS 3600 (Concrete Structures), AS 4312 (Atmospheric corrosivity), and manufacturer-specific product standards. Masonry repairs reference AS 3700. All Atomic Projects structural works are designed to meet or exceed current NCC performance requirements and the relevant Australian Standards for the repair method used.
