Geotechnical Investigations

Geotechnical Survey in Kenya, Uganda, Tanzania, Rwanda, Somalia, Sudan, DRC Congo, Mozambique, Zambia, and the rest of the East African region.

A geotechnical survey is an investigation of the physical properties and characteristics of the soil, rock, and groundwater at a particular site. The purpose of the survey is to provide information that is used in the design and construction of structures such as buildings, bridges, and roads, as well as for the evaluation of the stability and safety of existing structures. The survey typically involves drilling boreholes, taking soil and rock samples, and performing laboratory tests to determine the soil's engineering properties. The data collected during the survey is used to evaluate the soil's ability to support the intended structure and to determine the appropriate foundation design and construction methods.

We use various techniques to investigate the properties of soil, rock, and groundwater at a particular site:

  1. Borehole drilling: This involves drilling a hole in the ground to obtain soil and rock samples. The depth and diameter of the borehole will depend on the project's requirements.
  2. Cone penetration testing: This involves inserting a cone-shaped probe into the ground and measuring the resistance to penetration. This test can provide information on soil strength and density.
  3. Standard penetration testing: This involves driving a sampler into the ground using a hammer and measuring the number of blows required to penetrate a certain distance. This test can provide information on soil strength and density.
  4. Plate load testing: This involves placing a steel plate on the ground and measuring the deformation under a known load. This test can provide information on soil-bearing capacity.
  5. Ground-penetrating radar: This involves using radar to image the subsurface and detect buried objects or anomalies. This test can provide information on soil stratigraphy and the presence of voids or other features.
  6. In-situ testing: This involves testing the properties of soil and rock without removing them from the ground. Examples include pressuremeter testing and seismic testing.

Sectors we serve:

  1. Construction industry: for site selection, foundation design, and soil stabilization.
  2. Mining industry: for site investigation, slope stability analysis, and foundation design.
  3. Transportation industry: for road and railway construction, bridge foundation design, and tunneling.
  4. Energy industry: for site investigation, foundation design, and soil stabilization for wind, solar, and hydroelectric power projects.
  5. Environmental industry: for soil and groundwater contamination assessment, and landfill design.
  6. Coastal and marine engineering: for coastal and offshore structure design, soil and seabed analysis, and foundation design.
  7. Infrastructure projects: for large-scale infrastructure projects like dams, levees, and canals.
  8. Agricultural industry: for land improvement, irrigation, and soil fertility assessment.
  9. Telecommunications industry: for cell tower foundation design and site selection.
  10. Defense industry: for military infrastructure development and support.
