AMC responded to complete this emergency repair to Cook’s Sea Cave for the City of San Diego to ensure stability of the roadway and utilities above. Our scope of diving work included underwater welding, rock drilling, underwater pumping of erodible concrete, installation of 135 ballast blocks integrated with filter fabric to act as a breakwater, installation of steel bulkhead and welding of closure plate. AMC was proud to offer our diving services to help maintain such an environmentally pristine area so that it can continue to be enjoyed by the local San Diego residents and visiting tourists.
