Foundation Soils vs DrillerDB

Foundation Soils · checked October 6, 2026

DrillerDB is a water table depth lookup by address, built from recorded well logs. Foundation Soils is a reference site built from public data: soil, water table, drought and flood losses for the ground under US houses. They overlap, but they answer different questions. Use DrillerDB when you want a water table depth in feet for one address. Use Foundation Soils when you want expansive clay, water table, drought and flood losses for a county, city or ZIP on one page.

Foundation Soils is a reference site that earns referral fees, so read its side of this page with that in mind. Every fact about DrillerDB below was read from its own pages on October 6, 2026 and links to the page it came from.

When Foundation Soils is the better pick

A county or ZIP page here is a starting point. The soil under one lot can differ from its county, and what to do about a house is a question for a licensed engineer.
