Rotary Core Drilling

NCES Ltd endeavour to provide the most suitable and costeffective drilling techniques to suit client specification objectives and most importantly, varying ground conditions. At NCES Ltd, we can offer a variety of rotary drilling rigs for various different applications or access constraints. The use of this drilling method allows a wide range of high quality samples to be taken, which can be subsequently tested to obtain specific engineering characteristics that could not have been undertaken by the more conventional cable percussion boring method. Generally rotary drilling methods can construct deeper boreholes and have the added benefit of being able to penetrate and sample hard stratum. Two of our most popular rigs are detailed below and can be used to cover mosts ground investigation scenarios. Comacchio GEO 205.

Comacchio GEO 205 This rig has a powerful impact hammer mounted to the side of the main drill head, which can advance windowless sample barrels through soft over burden, giving a very high quality of sample. Once harder ground is encountered, the rig offers various options. It can continue drilling with hollow or solid stem augers, open hole, odex or even rotary case and core. The on-board 1 tonne winch allows for in-situ testing to be carried out as required during the drilling process. Comacchio MC 305 The MC305 is a compact and versatile drill rig mounted on a Bremach Extreme 9 four wheel drive vehicle. This rig is suited to all types of geotechnical and environmental ground investigations as well as geothermal wells and conventional water wells. The machine is capable of operating all rotary drilling systems, DTH. hammers, coring, both window and windowless sampling and in-situ testing including standard U100 sampling. General Features (GEO 205 & MC 305): Comacchio MC 305 Hollow stem augers Solid stem augers Auger casing system Open holing Drag bit drilling Rock rollers Odex drilling and casing system In-situ testing (SPT/CPT) Undisturbed rotary coring Air or water/mist flushing Windowloess sampling Borehole closure
