Where do i place the Dpm on a raft foundation?
Anonymous user 01/03/2024 - 2.58 PM
I'm working on a raft foundation detail at the moment and I'm not sure where to place the dpm, does the dpm need to go above or below the slab? if it goes below the slab would I have to wrap it around the thickened slabege of the raft foundation?
Are you a tradesperson and able to answer this question?

Your dpc goes at the same height as the existing building do you mean for the oversight for the slab if so that would be visqueen that would go under your slab on top of the hardcore and sand blinding before you add mesh then the. Concrete

If it's for an occupied structure it should go on top of the sand blind below the kingspan and also on top of the kingspan giving you double protection.
