Geotechnical Engineering

Geotechnical Engineering

Whatever structure is built, from the humblest dwelling to the largest dam, it is founded on the earth. The science and art of geotechnical engineering enables the designer to assess the quality of the foundations and adjust designs accordingly. Where earth structures such as dams or road cuttings and embankments are required, the geotechnical engineer plays a crucial role.

HHO Africa has had an in-house geotechnical section for many years. Not only does the section assist the HHO Africa design teams but it also meets the more specific needs of individual clients over a wide range of geotechnical problems. More recently the section has also become involved in environmental management particularly in relation to borrowpit development and rehabilitation.

Among the services that the geotechnical section can offer are:

  • Design and safety inspection of earth dams
  • Foundation investigations for roads, bridges and structures
  • Design of cuttings, embankments and retaining walls
  • Investigation and stability analysis of unstable slopes
  • Design of lateral support systems for excavations
  • Earth and rock anchor design and construction supervision
  • Sub-surface drainage systems to drain waterlogged soils
  • Location and investigation of construction materials
  • Environmental management programmes for quarries and borrow pits
  • Waste management and landfill design
