So I am in the middle of converting a small barn and trying to track down some water ingress I discovered that the previous owner built the back wall of the barn onto the internal screed DPM which ends outside - see pictures attached. This is causing water ingress on the inside on the floor all along the back wall.
Just wondering what would be the best approach to solve this?
I was thinking to cut the DPM short and build/pour a thick concrete plinth (as wide as the slab so it clears it) with an angle so water can run off. Is that a good solution? If so, what prep/mix would be best to get a good bond and make it as water tight as possible?
