Geotechnical Engineer
Soil and foundation engineering
What this life looks like
You ensure that structures are built on solid ground. Geotechnical Engineers investigate the properties of soil and rock, design foundations and earthworks, and address challenges such as slope instability, underground construction, and soil-structure interaction. Every major construction project starts with your expertise.
What she actually does
You conduct site investigations including borehole drilling and soil sampling, test soil and rock properties in the laboratory and field, analyse foundation options for buildings and infrastructure, design earth retaining structures and slopes, assess and manage landslide risk, advise on ground improvement techniques, and monitor the performance of geotechnical structures during and after construction.
Where you can work
| Sector | Places in Africa |
|---|---|
| Geotechnical Consulting | SRK Consulting (South Africa), Franki Geotechnics, Geotechnics Africa — site investigations |
| Construction Companies | Keller Geotechnical (Africa), Soil Engineering, Geostab — ground engineering contractors |
| Mining Companies | Anglo American, Glencore — mine stability and tailings dam management in Africa |
| Government Infrastructure | Roads agencies, dam construction authorities, urban development agencies |
Why it matters in Africa
Africa's diverse geology — from expansive clays to tropical laterites to swelling soils — presents unique geotechnical challenges for construction. As infrastructure investment grows across Africa, demand for geotechnical engineers who understand African soil conditions is rising sharply.

A woman in this field
Frannie Léautier
Tanzania
Frannie is a Tanzanian civil engineer who obtained her bachelor's degree from the University of Dar es Salaam and her PhD in Civil Engineering from MIT. She spent two decades at the World Bank, becoming head of the World Bank Institute, and later served as Executive Secretary of the African Capacity Building Foundation. Her career shows how geotechnical and civil engineering expertise becomes the foundation for leading major African development institutions.
Take your first step
- Study Mathematics and Physics at school
- Research civil engineering programmes at universities in your country
- Dig into the soil near you and observe its texture, colour, and drainage — this is the start of geotechnical observation
- Learn what a borehole investigation is and why it is the first step in any major construction project
