Concrete Repair (Cancer/Spalling)

Close up of concrete cancer before repair

Concrete cancer is a colloquial name for concrete degradation caused by contaminants or weather. It oftens refers to rusting of the concrete reinforcement bar (rebar), but also applies to other concrete failures.

Several forms of concrete defect can occur, but the major cause is water penetration to the rebar, which then rusts and expands, forcing the surrounding concrete to spall (break away).

Concrete cancer can be treated in most structures. Compatible Concrete Repair can remove the spalled concrete, clean and treat the exposed steel (or replace if possible), then repair to the original concrete profile using compatible polymer modified mortars.

Cracks are repaired using epoxy and polyurethane resins with specialised injection techniques.

CCR only use products compatible with the substrate for longevity of the repair and service life of the structure, hence Compatible Concrete Repair.
