About Foundation Soils
Foundation Soils (foundationsoils.com) is a reference site on the soil and water under US houses, launched in 2026 and built from USDA, NOAA, FEMA and Census data.
It shows where USDA rates clay soils as a problem for slabs, where water tables sit at basement depth, and how drought, rain and flooding line up with them. We aren't contractors, engineers or inspectors, and a page here isn't a substitute for an inspection of a particular house.

| Written by | Foundation Soils. Pages are generated from the data by scripts that check their numbers against values confirmed by hand. No person is named as an author. |
| How it's paid | Nothing yet: no phone numbers are live. When a page shows a phone number, the company that answers pays a flat fee per referral call, never a share of the job. How we get paid |
| What it doesn't do | No repair, waterproofing or inspection work. It never calls or texts anyone, and it lists no contractor reviews or ratings. |
| Not to be confused with | Foundation Soils is not part of any foundation repair or waterproofing company. Articles titled "Foundation Soils" on contractor websites, including Foundation Recovery Systems and AquaGuard Foundation Solutions, belong to those companies. |
