Covering ground under floor

[MConline]

Hi,

Im replacing a suspended wooden floor due to rot caused by no ventilation. New air bricks are in, i'm also insulating between the joists.

My question is; should I cover the bare ground underneath with a DPM sheet or leave it to breath?

Also should I use chipbaord screws (using 22mm chipboard flooring) or normal wood screws?

Any thoughts gratefully recieved.

Thanks.

MC

you can flop some polythene sheeet onto the bare soil, and weight it down. Fold up the edges into a tray to prevent water getting on top of it. This will reduce the amount of moisture under the floor. It will not be a total damp seal as I imagine you have sleeper walls which will be a bit damp.

Chipboard screws are for screwing into chipboard, but your threads will be going into the joists so this would not be the thread you need.

Thanks, John D,

Seems like a good plan.

Thanks again
