Geotechnical Investigation
Geotechnical investigation & soil testing in Edo State, Nigeria: borehole and laboratory soil tests for safe foundation design.
Field service run from our Benin City, Edo State headquarters. Projects outside Edo State are mobilised on request, with the same licensed professionals and reporting standard.
What We Do
Geotechnical Investigation tells you what is under your site before you pour a single foundation. We drill boreholes, sample and test the soil in a laboratory, and deliver a report with foundation recommendations your COREN engineer designs from: and your approval file requires.
What the Investigation Includes
- Borehole drilling and logging: soil layers and groundwater identified
- Laboratory testing: bearing capacity, compaction, moisture content
- Foundation recommendations: the footing type and depth for your actual soil
- Soil test report: the COREN-signed report your approval file needs
When You Need It
- Buildings above 10 metres: required by the Edo State approval process
- Filled or swampy land: the most common source of settlement problems
- Near water bodies: soft or saturated soils need proper design
- Previously used sites: old foundations, buried refuse and disturbed ground
The Process
- Scope and site visit: we plan borehole locations with your engineer
- Drilling and sampling: boreholes drilled, samples taken
- Laboratory testing: samples analysed by accredited methods
- Report: soil test report with foundation recommendations

Frequently Asked Questions
When is a soil test required in Edo State?
The building approval process requires a soil test report from a COREN engineer for buildings above 10 metres in height. It is also wise for any building on filled land, near water bodies or on previously used sites.
What does a geotechnical investigation include?
Borehole drilling, soil sampling, laboratory testing (bearing capacity, compaction, water table) and a report with foundation recommendations your engineer can design from.
How long does a soil test take?
Typically 2 to 3 weeks including laboratory analysis. It runs in parallel with drawing preparation, so it doesn't usually extend your approval timeline.
Can I build on a filled or swampy land without a soil test?
You can, but you shouldn't. Foundations on filled or soft ground are the most common source of settlement cracks. The test is cheap insurance compared to a failed foundation.
