Soil: Load-Bearing Worth
A soil test is the only way to truly know the load-bearing worth (LBV) of the soil for your intended footers. But beneath is a guide to standard soil kinds and their LBVs:
Bedrock: 12,000 (Pounds Per Sq. Foot)
Sedimentary rock: six,000
Sandy gravel or gravel: five,000
Sand, silty sand, clayey sand, silty gravel, and clayey gravel: 3,000

Depth of Footings
Footings should extend to a minimum of 12″ under undisturbed soil. Undisturbed soil is soil that has never ever been turned more than, tilled, graded, hoed, or something of that nature, by man or machine.
