Trenchless Solutions Ltd were asked to look at this project in Birkenhead which involved the installation of a Hobas DN600 drainage jacking pipe underneath private gardens , the total length of the drive was approximately 100m. Using the guided auger boring trenchless technique TSL suggested the drives to be split working from a central shaft. On the first 50m drive, the pilot bore was completed in one day, the casing and auger was installed in four days and the DN600 Hobas pipe was installed in one day, trenchlesstechnology at its best!
Ground conditions: VERY STIFF CLAY!
