GES on site at Nine Elms in London. A series of fully cored boreholes were drilled using a small top drive rotary rig to a depth of 70m using Geobore S Wire Line system and water flushing drilling techniques. Each borehole was\u00a0 pre drilled and cased down to London Clay. A 6\u201d diameter casing was\u00a0 left with a good seal into the Clay around 15.00mtr to allow flush returns. There was also\u00a0 a large enough pit around the casing to allow the suction hose to recirculate. The\u00a0 drill rig will be set up with a trailer mounted drilling pump capable of coring and open- hole drilling techniques. The TMAC rig was used which is\u00a0 rubber track mounted to minimise any damage to road surfaces. Another Successful project for Geotechnical Exploration Services.
