What concrete cancer is, and how we repair it
Concrete cancer is the name for steel reinforcement rusting inside concrete.
As the steel rusts it expands, cracking the concrete and pushing pieces off the surface, which is called spalling.
We cut back to sound concrete, clean and treat the steel or replace it where needed, and reinstate the concrete with a repair mortar shaped to match.
A protective coating or paint system then helps protect the repair and the concrete around it.
