Hi all, I've been looking at the site for a while and now need to ask a question if any one can help.....
We have a 200 year old cottage , we have done upstairs and now are starting on the ground floor. The floor was always damp and was constructed of a concrete pour over the uneven ground below with no dpc or any proper construction at all!!!!
I have removed the concrete and intend to dig out the uneven soil to allow for a suspended timber floor. I'm aware that we may have limited if any foundation and so have opted for a dwarf wall up the middle to keep the joist depth to a sensible minimum, allowing for DPC, oversite covering and ventilation.
Question is ...how much foundation will be needed to support the dwarf wall/floor. The span is 2.4m. I also intend to create a similar wall along the paralell walls again to support the floor to prevent loading the house walls as they are of rubble filled stone construction.
Any help appreciated, thanks.
