We remove all loose, spalling concrete and expose the rusted bar to a point at least 50mm beyond the limited of corroded steel. Our concrete experts then continue breaking out the concrete until the full circumference of steel is exposed.
Using a grinder, needle gun or other hand tool, we machine the corroded steel to a bright finish, taking care not to damage or cut any structural reinforcing bars. The exposed bright metal is then treated with a cementitious rust cover, and patched with approved repair mortar. This ensures the repair mortar suits the structural capacity of the area being repaired.
Please note that in cases of severe corrosion, a new section of bar may have to be inserted.
