Soil Boring and Soil Testing
Soil borings and lab testing to learn what is underground before you design or build.
What the work involves
Soil borings sample the ground at depth using a drill rig, with standard penetration tests and lab tests for moisture, plasticity, gradation and strength. They are the field portion of a geotechnical investigation and can be ordered alone for smaller projects. Results drive foundation type, excavation and drainage decisions.
Local conditions we plan for
- Deep frost penetration and frost heave
- Heavy snow loads
- Riverine and spring snowmelt flooding (Red River)
- Peat and soft organic soils
Building code: 2018 IBC/IRC adopted at the state level (ICC adoption chart, April 2026).
When you need it
- Before buying land for construction
- Planning a foundation or pool
- Suspected fill, debris or soft soil
- Groundwater depth needed
Frequently asked questions
How much does soil Boring and Soil Testing cost?
Across the US, soil Boring and Soil Testing usually costs $750 to $1,500. HomeAdvisor lists soil boring tests at $750 to $1,500, with additional borings commonly $400 to $800 each per cost-guide reporting.
How long does soil Boring and Soil Testing take?
Plan on 1 to 3 weeks from signed proposal to stamped deliverables, longer if a site visit, soil testing or a permit review cycle is involved.
Is a permit required for soil Boring and Soil Testing?
Often not on its own, but the findings frequently lead to work that does need a permit. We tell you which parts of the follow-up work your local building department will review, and can prepare those drawings too.
How do I verify an engineer's license in Minnesota?
Engineers practicing in Minnesota are licensed by the Minnesota Board of Architecture, Engineering, Land Surveying, Landscape Architecture, Geoscience and Interior Design (AELSLAGID). You can confirm a license number and its status in the board's public license search before you sign a contract.
How deep is the frost line in Minnesota?
Minnesota Rule 1303.1600 sets minimum footing depth for frost protection at 60 inches in Zone I (northern counties) and 42 inches in Zone II (southern and metro counties), unless an engineer competent. Local building departments set the required footing depth, so confirm the exact figure for your county before designing foundations or retaining walls.
Which building code applies in Minnesota?
2018 IBC/IRC adopted at the state level (ICC adoption chart, April 2026). Cities and counties can add local amendments, which is one reason to hire an engineer who works in your area.
