Hydrodemolition has its advantages in the removal of concrete, but a common complaint is the noise levels from the power packs that drive the machines. Looking to address this, Swedish-based Aquajet has launched the Ecosilence 3.0, an updated power pack for its hydrodemolition robots that increases the overall power, with options to significantly lower ambient noise levels.
While hydrodemolition can remove concrete while leaving rebar intact, it took extra effort to get all of the concrete out from behind the rebar, a requirement for many infrastructure rehabilitation projects. “Our earlier model was water-cooled, but customers wanted a more powerful machine,” says Roger Simonsson, president, Aquajet.
