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 pre drilled and cased down to London Clay. A 6” diameter casing was left with a good seal into the Clay around 15.00mtr to allow flush returns. There was also a large enough pit around the casing to allow the suction hose to recirculate.
The 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 rubber track mounted to minimise any damage to road surfaces.
