The BlackHawk BHK-100 hydro-demolition and scarification system from StoneAge can be universally mounted to a skid-steer, telehandler or other hydraulic equipment for horizontal or vertical work. Unlike mechanical methods for removing concrete, such as jackhammers, the BHK-100 cleans and decontaminates embedded metal elements and rebar in concrete without damaging adjoining infrastructure, leaving adjacent concrete sections intact and providing greater adhesion for bonding new concrete.

Weighing 1,200 pounds, the unit has a removal rate of 8.4 cubic feet per hour at 100 hp and can cut a path up to 48 inches wide. It has a flow rate up to 50 gpm and delivers up to 22,000 psi.

Designed for updating infrastructure, such as roads, bridges, spillways and parking garages, the unit also can be used for surface preparation and coating removal.

“The nice thing about the BlackHawk is by using high-pressure water you can perform concrete demolition in a precise and controlled manner,” says Randy Parker, marketing manager for StoneAge.

Unlike jackhammers, the attachment does not produce fracturing vibration or negatively affect the surrounding concrete. It also contains dust and debris associated with jackhammers and is simpler to use than more expensive hydro-demolition robotic machinery, he says.

“Not only is it useful for the hydro-demolition of concrete but you also can use it for the scarification of concrete and removal of coatings,” Parker says. “It’s not unlike doing surface prep with a shotgunning tool. You can adjust the pressure, flow and rate the unit travels across the concrete to best suit a range of applications.”

Operated through the use of an implement’s auxiliary hydraulic system, nozzle rotation and traverse speeds can be monitored via wireless display viewable from the driver’s seat. Operating height can be adjusted, along with rotation and traverse, to vary the amount of material removed.

“The operator can sit safely in the cab of the skid-steer and operate the unit using the auxiliary hydraulic controls, rather than out in the blast area,” Parker says.

“Once you have a setup, it’s easy for a second shift operator to continue the demolition process. He can dial in the same exact readings [rotation, traverse, height] and get the same constant result.”

The unit is equipped with a single-port nozzle for demolition; an optional scarification head is available. 866/795-1586; www.stoneagetools.com
