Rotary rigs can be used for sites that require deep drilling (>30mbgl), such as mining investigations or where there is a requirement for cores. Drilling can be open hole for fast drilling, to deep strata or cored, to provide solid samples to allow assessment of bedrock for geotechnical properties. Drilling can be air or water flushed, depending upon the type of investigation and the water source.
To ensure full health and safety compliance, all locations will be subject to an initial CAT and Genny survey as standard prior to drilling. In addition, a 1.2m hand dug pit will be excavated to establish service clearance.
