Micro tunnelling is a process that involves using a remotely controlled boring machine with a diameter less than a man’s combined with the pipe jacking technique to install a string of pipes underground, particularly in wet and unstable ground conditions, with the soils at the cutter face being controlled to maintain balance. This method avoids having long stretches of open cut trenches for pipe laying, which disrupt traffic and have a negative impact on the community.

This is currently the most precise pipeline installation method. Throughout the process, line and grade are meticulously monitored and maintained. When attempting to establish a new pipeline in an area where subsurface utilities already exist, this can be critical. Micro tunnelling installations are ideal for gravity sewer construction.
