Hi Tech were required to carry out hydro demolition of concrete to allow for the removal of two bridge bearings. Hydro Demolition was the method of choice assessed by Hi Tech's technicians, in order to successfully make way for re instillation of bridge bearings. The concrete needed to be removed quickly and safely, whilst ensuring the structural integrity of the bridge and remaining structures which included the steel reinforcement. High pressure water blasting was the preferred method of removal to not only meet the clients objectives, but due to the restricted head room and inability to access the rear of the bearing with jack hammers or other conventional tools. Hydro demolition via hand lancing successfully ensured that there was no damage to the steel, safe access to the working site and no micro cracking in remaining structure. Hi Tech utilised their King Vac 9000 to assist in the completion of the job, by collecting, removing and disposing of waste water off site.
