Aquajet Introduces Powerful Aqua Cutter 710V for Heavy-Duty Concrete Removal
Aquajet Systems has introduced its farthest-reaching unit, the Aqua Cutter 710V hydrodemolition robot. It’s the largest of its kind and offers exceptional horizontal, vertical and overhead reach — as high as 23 feet. The 710V comes equipped with Aquajet’s hallmark ceramic nozzles that last as much as 79 percent longer than standard steel versions. Its design makes it suitable for a wide variety of concrete removal tasks, such as renovation and bridge and road repair.
“We designed the Aqua Cutter 710V to give customers the ability to accomplish more work, even in hard to reach areas,” said Roger Simonsson, Aquajet Systems managing director. “The robot’s extended reach allows contractors to get at and remove concrete in areas other robots simply cannot.”
The 5,070-pound (2,300-kilogram) Aqua Cutter 710V uses 14,500- to 40,000-psi water jets to remove as much as 35 cubic feet (1 cubic meter) per hour of concrete. Contractors adjust the robot’s stroke to control the depth of cuts and vary the pressure of the water jet depending on whether they are removing loose, deteriorated concrete or lowering the sound concrete to a pre-determined depth. A valuable feature of hydrodemolition is that rebar is cleaned and descaled during the process, whereas alternative methods, such as pneumatic tools or milling machines, may damage the rebar or produce microfracturing in the remaining concrete.
Operators can control the 710V from a safe distance using the unit’s radio remote control, either wirelessly or with a hard wire. The remote communicates with the robot’s wheeled power control module.
Contractors use Aquajet’s unique cutting head, extended reach and its multi-axis 3D positioning system to efficiently operate on all horizontal, vertical and overhead areas that would be difficult to get at with other equipment. This includes straight up and down work, such as renovating walls, shafts and furnaces. In addition, the 710V easily removes concrete in corners that would be difficult to access with hand tools. Aquajet constructs the 710V’s steel mast in sections — an innovative design that gives the operator freedom to raise the front power head as high as 23 feet (7 meters) — 10 feet (3 meters) higher than the Aqua Cutter 410V — without additional support.
The 710V features a powerful 18-kW diesel engine. Contractors can add an Aquajet Hybrid Kit, which easily attaches to a diesel-powered Aqua Cutter robot for electric operation in applications where diesel engines aren’t allowed, such as parking garages, inside buildings or in other urban environments. The kit uses an intelligent system to automatically disengage the onboard diesel engine.
Aqua Cutter robots feature unique ceramic nozzles specifically designed for demanding hydrodemolition applications. The highly efficient nozzles last 300-350 hours, depending on the water quality. Standard steel nozzles on competitive equipment typically have a lifetime of 20-40 hours.
All Aqua Cutter robots feature Aquajet Systems’ patented Equal Distance System. EDS keeps a preset distance from the nozzle to the concrete surface, regardless of the angle of the water jet, allowing for maximum efficiency and productivity. Systems without EDS lose as much as 20 percent of the power before the water hits the concrete, greatly reducing productivity and increasing waste.
The 710V robot fits into Aquajet Systems’ 23-foot (7-meter) Power Packs. The large metal containers include a high pressure Hammelmann pump, large capacity diesel engine and control system, with a convenient storage area for the robot.
The hydrodemolition robot features unrivaled ease of access for all maintenance, allowing for minimal downtime. The unique gullwing hood and foldable back cover of the Aqua Cutter robot offers total access for both daily maintenance, such as checking oil levels, as well as periodic service jobs, such as oil and filter changes.
The robot also comes in a larger version, the Aqua Cutter 710V XL. The 5,357-pound (2,430-kilogram) 710V XL is 23 percent larger than the 710V, allowing for lower overall ground pressure and the ability to handle more reaction force.
The 710V and 710V XL are both compatible with Aquajet Systems’ line of accessories, such as rotolances and circular power heads, as well as spines and frames.

Researchers at the University of Cambridge are using microencapsulation technologies developed by Dolomite Microfluidics to develop self-healing construction materials. As highlighted in recent BBC News broadcasts, the Department of Engineering's Geotechnical and Environmental Research Group is developing microcapsules containing ‘healing' agents – such as minerals, epoxy or polyurethane – which can be added to building materials to allow self-repair of small cracks which develop over time. Dr Livia Ribeiro de Souza, a postdoctoral researcher in the group, explained: "Many composite building materials used in the construction industry – such as concrete – suffer fatigue over time, developing small cracks. We are hoping to overcome this problem by adding microcapsules filled with ‘healing' agents to the concrete before it is used. The idea is that, as cracks begin to form, they rupture the microcapsules, releasing their payload and stabilizing the material."

The RD-1200XT pavement-drying unit from Greenville, South Carolina-based Road Dryer, LLC, quickly dries asphalt and concrete pavement, allowing crews to pave or apply surface treatments or striping after just one pass. The unit, which blows heated air up to 300° F directly downward through multiple nozzles, eliminates the risk of "flying objects," and allows traffic to flow in nearby lanes — reducing congestion caused by traffic restrictions. Available as a simple-to-operate trailer- or truck-mounted unit, the RD-1200XT can be adjusted for 8-ft to 12-ft (2.4m to 3.7m) drying widths. Because it dries pavement on demand, it provides flexibility for contractors and government agencies to meet timetables by minimizing delays from weather- and project-related wet conditions.
