29th March 2009:

I got hold of some used foam sheeting which is used for packing and decided to use this to sandwich between the concrete and the walls.  Although I doubt it will provide much isolation I thought well, it couldn't hurt and it gives soft corners under the DPM when the concrete is poured.  I cut this into 250mm wide strips and scored it along its length at 100mm and folded it.  This allowed it to easily be placed into the corners and when taped it stays in place pretty well.
