Bore Hole Investigations

The detailed investigation of the surface conditions is best carried out by advancing bore holes in selected locations in the project site. GeoTech has the facilities to perform such drilling work in the overburden and in the bedrock. Extensive sampling of the soil, on site field tests and monitoring and observation of the sub surface conditions during drilling adds to the information that can be provided to the structural engineer for his designs.

Such drilling, sampling and laboratory testing of samples are carried out under strict supervision and in accordance with the standard codes of practice. In general the specification and recommendations of BS1377 are adopted, while other local and international standards are used as required by specific projects. Additional and specific tests are carried out to meet the structural engineer's specific requirements. Drilling work is usually done using NX size drills and casings. Larger or smaller size bore holes are possible to meet specific needs.
