Hello chaps,
I've got some fibre board underlay to lay down on a screed floor. The screed has been laid on a DPM and the concrete which the screed is on also lays on a DPM.
The fibre board instructions say that when laying on concrete/screed then I must also lay a dpm. Why is this? Given the above, do I need to?
Thanks.
