OnSite has years of experience using the underground technique of pipe jacking to install pipelines, culverts and cuts. Our 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 sizes range from 900mm up to 1800mm diameter.


Benefits of pipe jacking

  • Ideal for shallow installations under roads and railway lines
  • Horizontal technique of trenchless technology
  • Spoil removed from the hole via a conveyer belt
  • Can drill larger diameters than microtunnelling
  • Less resources needed compared to open cut
  • Smaller cost and quicker completion time
  • Public interference reduced
