Suitable for most projects, cable percussion boreholes are a tried and tested method of site investigation for returning information on overburden strata.
Using a 4 wheel drive towable rig, or a specialist cut down rig suited to restricted access locations, most sites can be investigated. In-situ testing techniques including Standard Penetration Testing, Permeability Testing, Borehole Vane Testing, soft ground sampling methods such as Piston Sampling, can all be carried out in the boreholes in order to provide information for geotechnical design. Disturbed and undisturbed samples are retrieved from the boreholes for inspection and logging by engineers and subsequent testing in our laboratories.
Causeway Geotech has several Dando 2000 and 3000 cable percussion rigs within our fleet. In addition to this, we have bespoke low-ground bearing units comprising specially adapted cable percussion rigs mounted on wide-tracked vehicles (Hagglund BV206 and Mooroka MST1100) for access over soft ground conditions.
