With this new removal technique, the top metre of the base is removed. A backhoe digs a hole around the concrete base once the tower is removed. Then an automated high-pressure water jet is set up to fire a jet of water up close and rotate around the concrete base, directing the thin, high-pressure stream of water, cutting deeply into the base, slicing both the concrete and the rebar inside. The water jet rotates around the concrete pillar firing the high-pressure water jet until it is done. The top metre of the top of the concrete pillar is then lifted off.
