Everything You Need to Know About Pipe Jacking

 · Pipe jacking is a term that describes a specific trenchless pipeline installation technique. It s also used in conjunction with other trenchless methods such as horizontal auger boring and microtunneling where the jacking process is used to push in a pipe into a prepared borehole.The pipe jacking described hereafter is the pipeline installation technique itself and not an accompanied process.
