Get the low down from HB Tunnelling

Article: Schools Out!

HBT were contacted by the client to assist with the installation of 250mtrs of 150mm foul line. As part of the development of the new residential housing development project, we were commissioned by McPhillips to provide new foul sewer connections for the development.

McPhillips Ltd. won a contract from Taylor Wimpey North West Ltd to provide the infrastructure and preparatory works for the scheme.

As the route for the new sewers ran very close to existing buildings & down a narrow street passing the primary school entrance there were concerns about disruption to the local community and potential settlement.

Investigation works led to the fact that Auger bore technology could be used.


With all this in mind the works where planned for the school summer break so HBT where called upon to look at workable solution to tick all boxes.

Upon taking all of this on board we opted to install the 250mtrs using our BM400 Guided Augerboring Rig by choosing a trenchless solution negated the risk for all.

The accuracy of line and level made guided auger boring the preferred installation method. 250 metres of 150mm ID Naylor Denlok clayware were installed in six shots to form the new gravity sewer.


All works where completed ahead of programme
