Why Your Building Approval Is Delayed

County building approvals require proper geotechnical investigation reports. Without them, your project stalls and costs escalate.

🏗️

Building Approval Rejected by County?

County engineers require certified geotechnical reports before issuing building permits. Without proper soil testing and foundation recommendations, your application will not proceed.

🧪

No Soil Testing Conducted?

Without proper soil investigation, you risk foundation failure, structural settlement, and costly remedial works. County approvals require evidence of adequate soil bearing capacity.

Frequently Asked Questions

What is a geotechnical investigation report and why do I need one?
A geotechnical investigation report is a professional assessment of soil and ground conditions at your building site. It determines soil bearing capacity, recommends suitable foundation types, and identifies any ground risks. County building departments require this report to approve building permits, ensuring your structure is safe and stable.
How long does a geotechnical investigation take?
A typical geotechnical investigation takes 3-6 weeks from site visit to final report delivery. This includes: site investigation (1-2 weeks), laboratory testing (1-2 weeks), and analysis and reporting (1-2 weeks). We provide a detailed project programme at the commencement of each assignment.
How many boreholes do I need for my building project?
The number of boreholes depends on your building size and site variability. For typical buildings, we recommend 1 borehole per 200-400m² of footprint. For large developments, additional boreholes may be required. We provide a tailored investigation plan after initial site review.
What is included in a geotechnical report for county approval?
Our geotechnical reports include: borehole logs, laboratory test results, soil classification, bearing capacity analysis, settlement calculations, foundation recommendations, and earthworks specifications — all formatted to meet county building department requirements.
Do you provide geotechnical services in all Kenyan counties?
Yes. We provide geotechnical investigation services across all 47 counties in Kenya. Our team has worked with county building departments in Nairobi, Kiambu, Mombasa, Nakuru, Kisumu, and many more. We understand the specific requirements of each county.
Who is qualified to conduct a geotechnical investigation?
Only EBK (Engineers Board of Kenya) registered engineers with proven geotechnical expertise are qualified to conduct site investigations and produce reports for county building approvals. Strasan Group has multiple EBK-registered geotechnical engineers on staff.
