Shed Damp Proof Membrane & Floor Insulation
by Clifford f Cheeseman
(West Lothian Scotland)
Thank you John and Greenboy for answering my previous query on shed roof.
I have another small problem
I am building a small workshop 8x12 in a garden that has a high level of clay.
The ground is wet much of the year.
I have set concrete blocks on edge in cement to the perimeter and intend to remove the soil(clay!)from the interior. I wish to backfill with paving slabs dry laid on sharp sand and mount the workshop walls on the concrete blocks.
I also wish to lay a damp proof membrane and include a 50mm polystyrene insulation within the build of the floor.
My question is: In what order do I lay/install the DPM and polystyrene insulation?
I would be grateful if anyone could advise me.
I have added a plan of the foundation Return to Shed floor
