NEWS

Foundation & Exploration Services has a new compact and versatile drilling rig for site investigations on difficult terrain.

The Commachio 405A is mounted on rubber tracks or a 4x4 carrier and is capable of working on embankments and cuttings. It can drill vertical or inclined boreholes and can be set up to carry out a variety of techniques including conventional rotary and wireline coring, open hole drilling and CFA work.

The flight auger system features undisturbed wireline sampling which is particularly suitable for geoenvironmental investigations because it is a dry-hole technique. Water or air flush methods can alter the insitu condition of soil and groundwater samples. Also fitted are a rod clamp/breaker and a rotary head incorporating fine feed hydraulic controls to increase productivity and for coring in sensitive, unconsolidated ground.
