Soil: Load-Bearing Value
A soil test is the only way to really know the
load-bearing value (LBV) of the soil for your
intended footers. But below is a guide to basic
soil types and their LBVs:
Bedrock: 12,000 (Pounds Per Sq. Foot)
Sedimentary rock: 6,000
Sandy gravel or gravel: 5,000
Sand, silty sand, clayey sand, silty
gravel, and clayey gravel: 3,000
Clay, sandy clay, silty clay, and clayey
silt: 2,000
Depth of Footings
Footings should extend to a minimum of
12" below undisturbed soil. Undisturbed soil is
soil that has never been turned over, tilled,
graded, hoed, or anything of that nature, by man
or machine.
