Hydrodemolition is the controlled use of water to demolish and remove reinforced concrete for reconstruction projects. It could be considered directed, focused, concentrated and extremely efficient erosion.

At Rampart Hydro, we use diesel power to generate ultra-high water pressures to clean surfaces and to remove reinforced concrete from various structures, such as bridges, dams, parking garages. While typical concrete can withstand forces of up to 3,000 psi, and high-strength concrete may withstand forces up to 10,000 psi, we apply (surprisingly) small volumes of water – 16 gpm per pump – at pressures up to 36,000 psi to literally blow it away. Concrete can be removed from depths of ¼ inch to 24 inches. Surface preparation can be controlled from a profile of CSP 1 to CSP 10. Fortunately, the debris (removed pieces, sand, and water) doesn’t travel far, so we efficiently vacuum and remove the debris. In fact, with dual units that contain both spray heads and large vacuum lines, the process may appear to be dry to an observer. With innovative and experienced employees, we build our own state-of-the-art equipment for use on surface cleaning projects, including airplane tire rubber removal on runways, to the demolition and removal of reinforced concrete on dams, bridges, parking garages, and other structures. Rampart’s state-of-the-art robotic equipment can remove concrete overhead, horizontally, and vertically to meet our customer’s needs. Rampart’s equipment can even perform underwater.

Rampart’s hand lance equipment and knowledge is known for its quick and efficient caulk removal, especially on T-to-T parking decks. Hand lancing technology also removes membranes from the tightest configurations, such as, behind guard rails, curbs, and corners. Bulk membrane removal is performed by programmed robotic equipment to ensure consistency.

From Boca Chica NAS (Naval Air Station) on Key West, Florida, to Denali National Park in Alaska and from Lewiston, Maine to San Diego’s Naval Base, all throughout the United States, our diligent, experienced employees harness the power of water to efficiently and effectively meet our customer’s most demanding removal specifications and constraints.

Our customers include:

  • The federal government and its agencies;
  • The Department of Defense, and the Army, Navy, Air Force, and Marines;
  • State, local and municipal governments and their transportation departments;
  • Many of the nation’s largest and busiest airports, and a few smaller ones, too;
  • Private corporations and organizations.
