A flexible and robust boring technique suitable for exploratory holes in many soils and groundwater conditions including made ground, clay, sands, gravel and weak or weathered bedrock materials. Typically operated to 40m depth although capable of move in suitable ground.
Capable of obtaining standard U 100 undisturbed samples, small and large bulk samples in a variety of ground conditions and piston samples, small and large bulk samples in a variety of ground conditions and piston samples in soft clay or peat.
The rig is also suitable for carrying out SPT's and water monitoring i.e: falling head tests and rising head tests.
Available with 150 mm, 200 mm and 250 mm diameter castings and drop tools if required, enabling deep borehole construction and sealing of various soil / groundwater horizons.
Suited for geotechnical and contaminated land investigations in most superficial materials. The boreholes are also suitable for permeability testing and long term monitoring instrumentation including those for gas, groundwater, ground settlement/heave, slip etc.
