Typical allowable bearing capacities

Appendix V: 9 Typical Allowable Bearing Capacities

Material Allowable Bearing
  Capacity (kN/m)
Plain concrete 2000 - 6000
Masonry or brickwork 1500 - 5000
Compact sands and gravels 300 - 600
Loose sands and gravels 150 - 400
Solid non-fissured rocks 600 - 3000
Hard clays and soft rocks 300 - 600
Stiff clays and sandy clays 150 - 300
Firm clays and sandy days 75 - 150
Soft clays and silts 0 - 75
Fill and made ground Variable

Note: The above values for soils apply where the foundation is 1m or more wide and at a depth of at least 0.6m. The allowable bearing capacity is about one-third of the ultimate bearing capacity.
