Sensitive underground cables and pipes can often be punctured by traditional digging methods. Utility Airspade offers a safe, non-damaging alternative for soil excavation. AirSpade’s patented, supersonic nozzle turns compressed air into a high-speed, laser-like jet moving at twice the speed of sound, Mach 2. All of the energy and momentum of air moving at approximately 1,200 mph is focused into the soil, dislodging it in a fraction of a second. Stronger, non-porous materials such as metal or plastic pipes, cables, or even tree roots are unaffected. The result is faster, safer, more effective digging.
