RepairQ A circular concrete tank built in the 1980s is to be resurfaced due to cracks in the exterior shotcrete lining. It has been proposed that the existing surface will be hydroblasted. Is there a concern that the shotcrete may contain asbestos?
No, there is no reason to assume that the shotcrete would contain asbestos. Shotcrete linings typically contain sand and cement. Asbestos was commonly used for pipe insulation and high-temperature industrial uses and not for shotcrete.
