Concrete Repair

Steel reinforcement in good quality concrete is normally protected by a ‘passive film’ produced by the alkaline conditions generated by the hydrated cement. Corrosion of reinforcing steel may occur specifically in concrete structures which are: Exposed to the atmosphere Manufactured with chloride based admixtures Located in industrial areas Manufactured with salt contaminated water, sand or aggregate Located in a salt water environment Concrete repair is almost always required when the steel reinforcing within the concrete structure reacts in the presence of water and rust begins to form, which can expand over five times the diameter of the reinforcing strand. The result is a build up of pressure that causes even the strongest to crack and eventually fall away.
Wherever steel exists in concrete there is always the potential for concrete spalling
Extensive concrete and structural repairs required to the asset of Owners Corporation is no problem when Consolidated is providing the expertise and experience.
Corroded steel reinforcement exposed and cleaned on the underside of stair flights. The steel has been treated and the structure is ready for reinstatement with repair mortar.
Steel balustrade posts embedded in a concrete balcony will eventually corrode and spall the concrete. If the corrosion is left unattended the ultimate result may also be the need to replace the entire balustrade. This can be avoided by chemical pressure injection if treated early enough.
Workface Access Is Where Building Repairs Starts
	Consolidated provides its own scaffolding and swing stages to gain access for façade refurbishment. Cost savings are passed onto the client.
MAGNESITE - PROBLEM	Owners Corporations are faced with the all too common problem of concrete repair resulting from home units affected by Magnesite. Magnesite was used extensively as a floor levelling material and to provide sound insulation. However when Magnesite absorbs water a corrosive mixture is formed which reacts with the covering layer of concrete.
	Consolidated Undertakes major repairs of unit blocks. This work requires investigation, break-out and concrete repair.
