Applied Earth Sciences · East & Central Africa
We read the ground, prove the materials and de-risk the build. From dam foundations on the Nile to transmission lines across the Great Lakes, our crews turn Africa's toughest sites into certainty you can build on.

Our primary mapping and geospatial division — the foundation every other mission area builds on. Topographic and geologic mapping, cross-border geodata coordination, drone and satellite remote sensing, 3D and BIM.
What we deliverScience that protects the health, safety and prosperity of people. Impartial environmental information for the continent's hardest land-management questions — on public land, at industrial sites, and in the communities that depend on both.
What we deliverThe mission area most clients meet first. Impartial scientific information on the continent's geologic resources and on the construction ground beneath every dam, port and pipeline — from critical minerals to foundation design parameters.
What we deliverFloods, debris flows, landslides, rockfall, collapses and earthquakes do not wait for preparedness to catch up. We monitor, assess and quantify the full range of natural hazards so that owners, operators and the public can act on numbers rather than fear.
What we deliverA large share of Africa's drinking water comes from groundwater. We monitor, assess and deliver information on streamflow, groundwater, water quality and availability — and confront the water dimension of climate change with science-based solutions.
What we deliverScience tells you what to build; someone still has to build it. This is where Tectonians put on harnesses, wetsuits and welding masks — in-water works, dam and powerhouse maintenance, industrial surface protection and power line construction.
