Sydney Marine Works

Hitech Industrial Services were contracted to carry out works that consisted of the removal of concrete via Hydro Demolition, enabling remedial works and Surface Preparation of the interlocking steel sheet piles in preparation for anti-corrosion coatings. The reason this method was chosen over standard shot blasting, being that Surface Preparation was also required under water. In areas of high surface pitting, fragments of garnet were introduced into the water jet to remove corrosion from the deeper pits.
