Concrete floor, extend DPM and fill void
I have a small void where previous owner made a back extension but didn't take the concrete floor right up to external door edge.
I need to fill the void with concrete.
Any tips on how folks would do this?
Fill void with concrete half way, then lay a piece of DPM overlapping with the existing bit, the extra concrete on top?
Or put insulation board in the void, then DPM on top, followed by concrete?
