London Site Investigation

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.

Another Successful project for Geotechnical Exploration Services.
