Trenchless Technology

Trenchless technology includes techniques for utility line installation, replacement, rehabilitation, renovation, repair, inspection, location and leak detection, that require minimum excavation from the ground surface. This includes directional drilling, microtunneling, moling, pipe ramming/pushing, auger boring, pipe jacking, utility tunneling, pipe relining, and various underground rehabilitation approaches. The technology is particularly suited for crossing projects and projects located within urban areas where surface disturbance must be minimized.
