Hi Tech were engaged to remove the concrete beneath a steel plate in a concrete dolphin, located on the coastline of NSW.
Hi Tech needed to expose the reinforced steel pins without causing any damage to them. We successfully removed the concrete via hand gun, with a two man crew, allowing for repairs and reconstruction. Extra flooring was also required to be removed along with sections of the concrete chamfer, due to cracks caused by ships docking. Encapsulation and filtration systems were put in place, by means of geofabric to ensure waste water did not enter the ocean.
