Microtunneling Projects Microtunneling is a method of steerable remote control pipe jacking, and is considered the most precise pipe jacking method. It can cover the longest distances, and can handle variable ground conditions. Generally, microtunneling doesn't cause much subsidence compared to other pipe jacking methods.         Project   Contractor Tolt Pipeline Project   Northwest Boring Beaver Water District Intake Expansion   Michels Pipeline Construction, Inc.
