Pipe bursting is a trenchless method of replacing buried pipelines (such
as sewer, water, or natural gas pipes) without the need for a traditional
construction trench. "Launching and receiving pits" replace the trench
needed by conventional pipe-laying.
Pipe bursting may also be used to expand pipeline carrying capacity by
replacing smaller pipes with larger ones, or "upsizing." Extensive proving work
by the gas and water industries has demonstrated the feasibility of upsizing
gas mains, water mains and sewers. Upsizing from 6 inche to 8 inche
diameter is now well established, and pipes of up to 24 inche diameter and
greater have been replaced.
Pipe Bursting Pneumatic

90% of all the pipe bursting in North America is completed using a
pneumatic system. From 4-inch through 54-inch diameter pipe.
