There is a DPM under the screed but I just had a call today saying they have changed their minds and going to put timber back down! Thats fine I was only starting Monday!!!!

Thanks everyone for all your responses.

He is asking if there is a DPM under the screed and commenting on the fact that where there is chipboard and floodds the chipboard will blow and fail.... I think

Don't think the DPM is need in this instance , the floor was a timber joist floor supported with the brick pillars/walls in the ' floor space'.
Can't see the flooding being relevant, as every floor in any circumstance with any substrate can flood and fail

Unless I'm completely reading it wrong [emoji15]
