The purpose of this investigation was to assess the ground conditions likely to be encountered during the installation of a new sewer and to assess the stability of the slope, as the site lies within an area of known landslip within the Stroud Valley in Gloucestershire. Ground investigation work was undertaken at the crest, mid slope and toe of the site. Staging was built to safely position the drilling rig for the mid slope borehole. Inclinometers were installed in the boreholes.
