Substructure and ground-bearing floors

Also see:

5.1.3Transfer of loads

Substructures and ground-bearing floors shall ensure that loads are supported and transferred to the foundations, or ground, without undue movement.

The design of the substructure should take account of findings from the site investigation. Where infill deeper than 600mm is needed, a suspended floor should be used.

Load-bearing partitions should have proper foundations and not be supported off ground-bearing floors. In Scotland, sleeper walls should not be built on ground-bearing floors.
