1. Concrete Patching:
Concrete patching is a widely-used technique to repair localised areas affected by concrete cancer. Remediation contractors in Sydney or anywhere else in Australia use a high-quality bonding agent to fill and seal the cracks and voids in the concrete. This method stops corrosion and aids in restoring the building’s structural integrity by keeping moisture and impurities from penetrating the concrete. Concrete patching is particularly effective for early-stage concrete cancer cases, where the damage is limited to specific areas.
2. Carbon Fibre Reinforcement:
In cases of more severe concrete cancer, where the corrosion has weakened a larger portion of the structure, carbon fibre reinforcement is an effective solution. Remediation contractors use high-strength carbon fibre sheets to reinforce and strengthen the affected concrete elements. These sheets are easy to install and lightweight, making them ideal for repairing columns, beams, and slabs. Carbon fibre reinforcement restores the building’s strength and prevents future concrete cancer occurrences in the treated areas.
3. Cathodic Protection:
Cathodic protection is an advanced technique used by remediation contractors to safeguard steel-reinforced concrete from corrosion. This method involves placing sacrificial anodes on the affected structure, which attract the corrosive elements and protect the steel reinforcement. By utilising cathodic protection, contractors can halt the progression of concrete cancer and extend the lifespan of the building significantly. This technique is especially useful for structures situated in corrosive environments, such as those near the coast.
4. Shotcrete Application:
Shotcrete, or sprayed concrete, is a versatile and efficient technique used to repair concrete cancer in hard-to-reach areas or when the damage is extensive. Remediation contractors utilise specialised equipment to spray a mixture of cement, sand, and additives onto the affected surfaces at high velocity. The shotcrete forms a durable layer that adheres tightly to the existing concrete, effectively restoring the structural integrity of the building. This technique is particularly beneficial for repairing tunnels, bridges, and multi-level car parks.
5. Epoxy Injection:
Epoxy injection is a precise and effective method to repair cracks caused by concrete cancer. Remediation contractors use specialised equipment to inject epoxy resins into the cracks, effectively sealing them and preventing further damage. This technique not only stops water infiltration but also restores the structural integrity of the concrete. Epoxy injection is popular for repairing deteriorating concrete elements such as walls, slabs, and foundation footings.
