Somerville High School Retaining Wall Hydrodemolition

AK Industrial Services performed hydrodemolition to remove 220SF of concrete from the face of a retaining wall at a depth of 4”. The GC favored hydrodemolition for this project because it would only remove the deteriorating concrete. It would preserve the existing reinforcing steel and not damage the existing sound concrete.

Using hydrodemolition allowed the GC to pour the new face of the wall without removing or replacing existing reinforcing steel. This method also prepared the substrate to solidly bond with the new concrete.
