Hydrodemolition Tractor

Our robotic tractors form the core of our concrete removal fleet. These tractors, which are designed and built by Rampart, are computer controlled and completely automated.  The computer control provides reproducible uniform concrete removal.    The tractor can be connected to our vacuum trucks to provide continuous removal of wastewater and demolition debris. 

The basic four-wheel-drive tractor has a cutting width of between two (2) and seventy-nine (79) inches.   The depth of removal is determined by the computer controlled speed of the waterjet over the surface.   For shallow removal (scarification) the waterjet moves quickly while for deeper removal (partial and full depth) the waterjet moves more slowly.  The unit can cut to a depth of between one-quarter (¼) inch and fifteen (15) inches in one pass.

Using a high-speed rotating nozzle, our hydrodemolition tractor delivers a 36,000-psi water jet that contacts 100 percent of the surface, providing a more uniform removal than traditional oscillating nozzles.

Our hydrodemolition tractor removes concrete to a specified average depth and leaves a rough surface of exposed aggregate, which maximizes the bonding with the new material. Hydrodemolition will also remove deeper, adjoining, and concrete if it is delaminated or deteriorated further improving the quality of the repair

Vacuum Tractor

Rampart Hydro vacuum tractor performs dry-hydro scarification

Rampart’s Hydrodemolition Tractor can be connected to our vacuum truck to control the wastewater and collect the debris.

Rampart’s Vacuum Tractor captures about 95 percent of the hydrodemolition wastewater to assist in proper water disposal.  Vacuum collection of the wastewater reduces the environmental impact on neighboring lakes, streams and watersheds and avoids the danger of wastewater entering adjacent active traffic lanes..

Vacuuming is also very useful when cutting and removing concrete on sloped surfaces and roadways where water would otherwise run into live traffic, creating a potential traffic hazard.
