Pipebursting
Only a minimum of digging is required, an insertion pit in or near the building
and a winch pit at the property line, the street or in the lane. Once the
pits are excavated, a cable is pulled through the old sewer pipe. The bursting head
is attached at the Insertion pit and winched through.
As the head bursts the old pipe and pushes it into the surrounding soil,
it also pulls in the new pipe. An expander on the Head increases the diameter
slightly so the friction on the new pipe is not significant. When the new
pipe reaches the Winch pit it is then detached and the new line is then
hooked up. Finally it is video inspected to ensure a successful installation.
Benifits of Pipebursting include:
- Lower risk of damage to underground utilities
- Work can generally be completed in about 2 days
- Offers a continuous pipe with plastic welded joints
- Pipe bursting replaces the sewer service without having to dig up the whole yard
- Is the environmental solution
- Uses Patented British Gas Technology
- Uses High Density Plastic Pipe (HDPE) ensuring strength and durability
- Can be used under trees, sidewalks, fences, retaining walls, garages and flower beds with minimal damage
