Water-jet tool roughens concrete surfaces

Aquajet’s Aqua Cutter 710 Aquajet Systems AB, a company that makes hydrodemolition machines, recently launched the Rotolance 1000 and Rotolance 2500. The powerful tools work in conjunction with Aquajet’s Aqua Cutter 710 hydrodemolition robots as well as the Aqua Spine and Aqua Frame to deliver water pressures in excess of 36,000 psi through a specially designed pattern of nozzles.

The Rotolances effectively clean, remove and roughen concrete surfaces, leaving a better bonding surface for new concrete or alternative materials. They can be used for applications including roads, bridges, airports, harbors, sewage pipes and water reservoirs.

Contractors also can use Rotolances to remove rubber coatings, paint, rust, plastic and other materials. It serves as a light-removal alternative to Aqua Cutter robots meant to remove deeper sections of concrete.

The attachment can be operated around the clock due to its computer-controlled automation.

Hydrodemolition uses high-pressure water jets to precisely remove sound, deteriorated or damaged concrete. The sustainable method leaves rebar undamaged while protecting and preserving existing concrete. The method eliminates vibrations that cause microfracturing and minimizes exposure to harmful silica dust. Hydrodemolition also leaves a uniformly scarified surface ready to accept new material.

Both Rotolance models can cover a surface diameter as wide as 14 inches. Their removal method creates no dust pollution as the attachments make sand blasting unnecessary. The attachments feature unique ceramic nozzles specifically designed for demanding hydrodemolition applications. The nozzles last 300-350 hours, depending on the water quality.

Both models weigh about 242 pounds (110 kilograms) and easily attach to Aquajet’s 710 Aqua Cutter hydro­demolition robots.
