Pipe Jacking

Pipe jacking is an underground technique for the installation of pipelines, culverts and ducts. This is a technique in which powerful hydraulic jacks push well designed pipes through the ground behind a shield. Whilst the pipe is pushed through the earth, excavation takes place within the shield.

Pipe jacking benefits include:

Excellent flow of characteristics after smooth internal finish.

No disruption to traffic or pedestrians

No requirement for a secondary lining

Minimal surface disruption

Less joints than a segmental tunnel
