Sydney concrete cancer repairs Northern Beaches.
WHAT IS CONCRETE CANCER?
Concrete cancer, also called concrete spalling, is caused by carbonation of the concrete, a natural deterioration process. This causes the steel bars embedded in the slab to rust and expand which in turn causes the concrete to bubble, crack and bulge. This is a common problem when there is not enough concrete cover over the steel.
CONCRETE CANCER REPAIRS
We use the latest mortar repair and corrosion inhibitor products and applications to remediate these issues.
MAGNESITE REMOVAL
Magnesite should always be removed, and the concrete should always be inspected for any concrete cancer.
Magnesite is found in the flooring and is made of a mixture of a powder and a magnesium chloride solution with various fillers such as wood flour and saw dust. It was used as a floor topping or levelling product up until the 1980’s.
When the magnesite absorbs water, the glue used in the flooring can leak into the concrete floor and corrode the steel reinforcement bars causing the concrete to expand and result in concrete cancer.
