Geotechnical Investigation

National Laboratory operates as an independent company serving Consulting Engineers, Government Departments, Industrial Developers, Oil Companies, etc. Technical staff is employed and where necessary trained locally and in some cases a joint venture is set up with local or international geotechnical consultants. Highly qualified technical staff is available to deal directly with enquiries and to maintain close contacts with clients and their design staff.

From our experience in the construction industry, National Laboratory is able to give advice on the geotechnical aspects of a variety of problems, such as the design of foundations, major excavations and earthworks, road and bridge works, pipelines and foundations for various structures.

In addition, we can design and plan site investigations, prepare specifications and provide site supervision.

From the results of boreholes, field and laboratory tests obtained from site investigations, suitable foundation types can be recommended and safe loading and settlement characteristics estimated.

Our services in the site investigation and drilling field include:

•On-shore drilling for site investigation for roads and bridges, housing structures, multi-storey buildings and towers and petrochemical complexes and refineries.
•Near- shore drilling for site investigation for marine structures.
•Geological exploration.
•SPT Testing and Sampling.
Rock Coring and Sampling
•Dutch Cone Testing.
•Pressuremeter Testing.
• Packer testing.
•Geophysical Testing.
• Ground Water Sampling.
• Ground Water Level Measurements.
• Ground Water Sampling
• Installation of uPVC Standpipe Piezometer
In-situ permeability test,
