ACS are working throughout the night on the M27 as part of the J4 to J11 motorway scheme for bmJV. We are utilising our trailer coring rig Excalibur Neptune T5 to quickly and effectively core through the pavement material. Following coring, shallow windowless boreholes are drilled using one of our Dando Terrier Site Investigation rigs including Standard Penetration Testing (SPT) at regular intervals. Full sample recovery in plastic liners is allowing detailed logging in accordance with BS 5930 and laboratory analysis for geotechnical index properties. ACS are providing a “One stop Shop” of geotechnical services including NVQ certified lead drillers, Chapter 8 compliant vehicles, Safety Critical Medicals, UKAS laboratory testing & certified and maintained drilling equipment.
