Pipe Jacking is a specialist tunneling method for installing underground pipelines with minimal surface disruption. Powerful hydraulic jacks are used to push the pipes through the ground behind a shield, all while the spoil is being excavated by workers inside the pipe, auger, or slurry.
Pipe jacking can be done above or below the water table. Pipe jacking requires thrust and reception pits for the hydraulic ram to brace against as they force the pipe through a bore. HDD Willco offers concrete pipe and Hobas pipe, a fiberglass reinforced polymer mortar pipe.
