This allows air flow and ventilation to prevent the mould and dry rot that would otherwise occur over damp ground.
Suspended timber ground floors consist of the finished timber floorboards being attached to floor joists which are suspended above the subfloor of the foundation.
These can be classed as either suspended or solid.
Solid floors are a lot more substantial and require the ground to be made up in layers of ground sub base sand compacted hard core damp proof membrane insulation and concrete.

Ventilation is required in the same way as a suspended timber floor.
