Concrete spalling, often referred to as "concrete cancer," is a serious threat to the longevity of multi-storey buildings. It occurs when moisture reaches the internal steel reinforcement, causing it to rust and expand, which cracks the surrounding concrete. In coastal Sydney suburbs, this is accelerated by salt air.

Ignoring spalling is not an option; it is a structural risk that increases in cost exponentially the longer it is left. Sydney Building Construction Group provides specialist concrete repair services. We identify affected areas, treat the steel reinforcement, and reinstate the concrete with high-strength structural mortars. Our remedial works extend the lifespan of your asset and ensure the safety of residents and passersby.
