About the Project: Concrete Holding Tank Repair in North Queensland

WS Remedial Group was commissioned to undertake comprehensive structural repairs to a leachate holding tank in North Queensland. Leachate tanks, used for the storage of contaminated water, are critical infrastructure assets that must resist aggressive environments and uphold strict regulatory standards. Over time, exposure to chemicals and moisture can lead to concrete deterioration, structural cracking, and corrosion of reinforcement, all of which compromise tank integrity and service life.

Targeted Concrete Repairs for Long-Term Durability

Our specialist team performed targeted concrete repairs on the leachate tank’s walls and floor. By addressing areas of surface distress and localised spalling, we restored the structural strength and improved the wear characteristics of the concrete. This approach helps to mitigate the risk of a corrosive environment developing around the embedded steel reinforcement, significantly extending the tank’s operational lifespan.

Structural Rehabilitation with Epoxy Crack Injection

One of the primary challenges was the presence of structural cracks that threatened water tightness and asset reliability. Using precision epoxy crack injection techniques, our technicians were able to fill and seal even hairline fractures. Epoxy injection re-bonds separated concrete, prevents water and chemical egress from the tank, and restores the original load-bearing capacity—crucial for tanks subjected to hydraulic and chemical stressors.

Advanced Protective Coatings for Chemical Resistance

Following structural repairs and crack remediation, high-performance protective coatings were applied to the internal tank surfaces. The selected coating system delivers exceptional chemical resistance and moisture protection, acting as an impermeable barrier against leachate and external contaminants. This final step greatly enhances durability, reduces future maintenance costs, and safeguards client investments.

Compliance with Queensland & National Standards

All materials and methodologies used by WS Remedial Group are fully compliant with Australian Standards for concrete structures and water infrastructure (AS 3735 and AS 3600), as well as relevant Work Health and Safety (WHS) regulations. Our project planning accounted for the specific environmental and operational conditions of North Queensland, ensuring robust performance in tropical climates and aggressive service conditions.
