Building Concrete Repair in Adelaide


Cracking, crumbling exposed rusty reinforcement steel are all signs of spalling Concrete Cancer. When treating the concrete cancer any rust affected steel must be exposed, cleaned treated and/or replaced. The area is repaired to the original concrete profile using cement mortar, and epoxy mortar or concrete - depending on the size of the damage and any structural requirements. Cracks are repaired using suitable epoxies, special mortars and injection techniques and the entire area is then treated with a protective coating.
