Geophysical Studies & Testing
National laboratory geophysical department department is under construction. However, we have a wide range of an approved independent geophysical studies specialist subcontractorsproviding a conscientious and reliable services through highly-qualified staff and modern equipment serving Consulting Engineers, Government Departments, Industrial Developers, Oil Companies, etc.
Through this service we provide an integrated suite of onshore and near-shore geophysical services for investigating the ground and the built environment. Surface as well as borehole geophysical surveys are provided where the latest techniques and advanced analysis software are employed for data acquisition, processing and interpretation of results. Modern equipment and skilled staff are readily mobilized to carry out comprehensive geophysical investigations and studies in the region in order to meet the clients’ needs and expectations effectively and in a timely manner.
