Thanks for all your replies.
What do I need to fill the gap with under the DPM, as surely it will just fall down the cavity when I put screed or concrete on top ?
Hello,
I know it’s most probably been mentioned a million times already but I am struggling to find a post that helps.
I’m looking to to properly fill in the cavity gap between the floor and my binfolding doors.
The gap is about 90cm deep
(Please see below photo)
Any help is much...
