i.e: brick sides on concrete base... etc etc:
and about how deep is the main floor slab!
Concrete floor. brick sides and 5.5ft deep. 2.2ft wide.
I have actually started filling in the pit today. Filling it in with rubble/subsoil and then going to put type 1 scalpings in the last 6 inch. then concrete over the last of it. Using my wacker at every stage. I'm not going to put the concrete over straight away i will continue to keep wacking it over the next few months then concrete it to try and make sure it doesn't sink over time.
Having read through the web that seems to have been the solution for people suffering the same problem of the damp and condensation.
