Pipebursting

Replaces a sewer by breaking and displacing the existing piping and installing a replacement pipe in the void created
System uses a pneumatic or hydraulic bursting unit to split and break up the existing pipe, compressing the materials into the surrounding soil as it progresses
New replacement pipe is simultaneously pulled or pushed with the bursting head to fill the void created
Upsizing to about 30% greater than the original pipe diameter is possible
Maximizes flow capacity of the existing pipe with minimal excavation
Preferred solution for high profile areas; less surface disruption to surrounding business and the environment
