A combination of technical expertise across four specialized laboratories
Independent laboratory science for infrastructure that lasts


We specialize in testing and validating engineering materials to ensure quality and compliance for infrastructure projects, from site investigation to final certification.
Dedicated to Ensuring Quality and Compliance in Every Material We Test
Geotechnical Testing
Borehole logging, soil classification, and CBR testing to determine subgrade strength for roads, foundations, and embankments.
Building Materials Testing
Concrete, cement, and steel testing — compressive strength, tensile yield, and bend testing to verify structural material quality.
Transport & Pavement Testing
Aggregate, bitumen, and asphalt mix testing to ensure pavement durability against West Africa's heavy rainfall and traffic loads.
Environmental & GIS Testing
Water, soil, and air quality monitoring, plus GIS and drone mapping, to support EPA permitting and lender compliance.

The Future Home of SELA Is Taking Shape
Our Advanced Engineering Laboratory Complex is being developed on a 12-acre site in Marshall City, Margibi County. This is more than a building — it is the foundation of a vision for civil engineering materials testing in West Africa, with every laboratory space designed to deliver precision, accuracy and excellence to every project we touch.
Watch this space.
Get started with SELA. From site investigation to final certification, we provide the independent, standards-based technical evidence your infrastructure project needs, delivered onshore without the cost and delay of testing abroad.
