Suspended Timber Ground Floor Construction Details

Floor construction concrete or timber floor.

Suspended timber ground floor construction details.

This allows air flow and ventilation to prevent the mould and dry rot that would otherwise occur over damp ground. These can be classed as either suspended or solid. Unlike standard ground floor construction suspended floors are not sitting directly on the ground. This construction is similar to the timber floor above but uses either pre cast concrete planks or small pre cast concrete beams with concrete blocks laid between the beams.

There are 2 types of floor construction used in construction today. These floor joists are raised above the subfloor on small supporting walls called tassel walls or sleeper walls. They can normally span greater distances than timber joists. 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. The big benefit for choosing a suspended floor whether concrete or timber is that the construction is simple. 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.
