Somerville High School Retaining Wall Hydrodemolition

Project Overview

AK Industrial Services performed hydrodemolition to remove 220SF of concrete from the face of a retaining wall at a depth of 4”. Hydrodemolition was preferred over mechanical concrete removal methods as it was important to preserve the existing reinforcing steel and not damage the existing sound concrete.

Using hydrodemolition to remove the old concrete allowed for the new face of the wall to be poured back in place without removing or replacing existing reinforcing steel, as it wasn’t damaged in the process. This method also prepared the substrate to solidly bond with the new concrete.
