Cable percussion drilling (shell and auger drilling)
For site investigation and geotechnical work, cable percussion (or shell and auger) drilling is by far the most common drilling method. It’s reliable – in almost any type of ground – and highly cost effective.
Geologic Boreholes operates a range of cable percussion drilling rigs to meet a wide variety of geotechnical, environmental and water borehole drilling needs. These drill diameters ranging from 150mm to 300mm and drill depths up to 100 metres.
Such cable tool drilling uses a ‘clay cutter’ tool, in cohesive soils, or a ‘shell’ (or bailer) tool, in non-cohesive soils. Both enable collection of disturbed soil samples, sufficient for determining the characteristics and structure of sub-surface materials.
For very hard ground, the drilling technique will also support the use of a chiseling tool. Water samples taken at different depths can also be obtained using cable percussion drilling.
