What to check before hiring in Ridgeway
- Check the soil map: the USDA Web Soil Survey shows the mapped soils of your parcel, including shrink-swell (expansive clay) potential. It does not replace borings, but it helps you ask the right questions.
- Code requirements: building codes based on the International Building Code and International Residential Code call for a soil investigation where expansive, compressible or questionable soils are likely; the building department of Ridgeway or Harrison County can require a soils report before issuing a permit.
- License: a geotechnical report must be sealed by a Professional Engineer licensed in Missouri. Ask for the PE license number.
- Price drivers: number and depth of borings, site access for the drill rig, laboratory testing and the size of the structure.

Frequently asked questions in Ridgeway
Do I need a soils report to build in Ridgeway, MO?
Often yes for a new home, an addition on questionable soils or any commercial building: the local building department decides, based on the building code and known soil conditions. A geotechnical engineer can tell you quickly whether your project needs one.
How much does a geotechnical investigation cost?
It depends on the number and depth of borings, the lab tests and site access. A small residential soils report costs much less than an investigation for a commercial building. Describe your project to get quotes from firms that serve Ridgeway.
