The contractor had several strip seal bridge joints encased in elastomeric concrete that were temporarily installed for phase construction. The contractor removed the bridge joints with the elastomeric concrete still attached. The elastomeric concrete need to be removed (without damaging the steel) so that the joints could be installed permanently. Due to the physical qualities of the elastomeric concrete, the use of conventional chipping guns was difficult and time consuming.
AK performed hand held hydro-demolition of the elastomeric concrete. Not only did the use of hydro-demolition save the steel, the removal was performed considerable faster than conventional chipping which saved the contractor time and money.
