Concrete Cancer Repair
Concrete cancer occurs when moisture penetrates reinforced concrete and causes the internal steel to corrode. As the steel rusts, it expands – cracking and dislodging the surrounding concrete from the inside out. In coastal Queensland, salt air and humidity accelerate this process significantly.
Early concrete cancer repair is cheaper and structurally sounder than waiting. Our concrete cancer repair process covers:
- Removal of deteriorated concrete to expose affected steel
- Rust treatment and corrosion inhibitor applied to steel reinforcement
- Reinstatement with a high-build, shrinkage-compensated repair mortar
- Appropriate waterproofing to prevent moisture re-entry
- Protective coating matched to the substrate and exposure level
Amalgamated's concrete cancer repair work covers floor slabs, stairs, balconies, soffits, columns, beams and broadwall sections. For high-rise buildings, our IRATA-certified rope access team carries out concrete cancer repair at height without scaffolding – see our high-rise painting page for how we manage access on multi-storey projects.
Waterproofing Brisbane
Waterproofing isn't a finish – it's a foundation. Applied correctly before protective coatings, waterproofing in Brisbane protects concrete surfaces from the moisture and salt air that cause spalling, delamination and structural deterioration over time.
Amalgamated applies waterproofing systems across:
- Balconies and podium levels
- Soffits and external ceilings
- Planter boxes
- Roof decks and concrete roofs
- Retaining walls and basement structures
We use fluid-applied membranes, trowelled cementitious coatings and layered fabric-reinforced systems depending on the substrate, exposure level and water ingress history. For waterproofing in Brisbane on strata complexes and high-rise buildings, our in-house team combines waterproofing application with any concrete repair work required – one mobilisation, not two.
High-pressure water-blasting is carried out ahead of waterproofing and coating application to remove salt deposits and surface contamination. Buildings in coastal areas benefit from a wash-down every three years to extend coating life.
Building Rectification Brisbane
Building rectification in Brisbane covers the broader scope of structural and protective repairs – from steel corrosion treatment to epoxy crack injection and compliance upgrades.
Amalgamated's building rectification work includes:
Corrosion treatment
Preparation and protective coating of structural steelwork, columns and fixings. We use multi-coat systems suited to the exposure environment, with product selection from Dulux and Taubmans ranges.
Epoxy resin injection
For structural cracks in concrete, epoxy injection bonds fractures permanently – the repaired section is typically stronger than the surrounding substrate.
Cladding and safety compliance
External cladding inspections, reports and rectification for buildings subject to fire safety and building code requirements.
Podium and basement water ingress
Assessment and repair of construction joints, failed flashings and podium-level ingress before waterproofing is applied.
Our building rectification Brisbane work is managed alongside painting wherever possible. Defects identified during a repaint assessment are quoted as part of the same project scope – not added as a separate contract after the fact.
