Unlike standard ground floor construction suspended floors are not sitting directly on the ground. Construction studies drawing detail of suspended timber floor.

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. Supports underneath the floor are permanent and include sleeper walls or timber props placed at regular intervals. Ventilation is required in the same way as a suspended timber floor. There are 2 types of floor construction used in construction today.

The big benefit for choosing a suspended floor whether concrete or timber is that the construction is simple. Suspended timber ground floors consist of the finished timber floorboards being attached to floor joists which are suspended above the subfloor of the foundation. This allows air flow and ventilation to prevent the mould and dry rot that would otherwise occur over damp ground.
