Specialists in Geotechnical & Environmental Drilling, Wireline Coring & Geobor-S
ADP Group crews are proficient and skilled in the provision of rotary drilling techniques, and can deploy various methods via modern, multi-purpose rotary rigs to achieve good core recovery and accurate results, in any geological formation.
Boreholes can be drilled with a combination of dynamic sampling and rotary coring; rotary casing or hollow stem augers are used to progress through any geology encountered. At any stage within a borehole, both undisturbed sampling and geotechnical testing can be carried out.
Boreholes can be progressed via dynamic sampling and rotary coring, to depths in the order of 200m. Wireline coring can be used as an alternative to conventional coring, aiding efficiency at greater depths, providing good core recovery in softer formations and class 1 samples. Both air and water flushing mediums can be utilised to assist borehole progression. ADP Group crews are experienced in the investigation of potentially contaminated sites, and can implement measures to accommodate both yellow and red category sites.
Dual casing systems can be installed to provide environmental seals in heavily contaminated soils.
