Hi all,
I'm currently designing an outbuilding - 6.3 m x 7.1 m.
I've made the decision to use a slab (sometimes called raft) foundation.
I'm having difficulty deciding on the best way to DPC the slab. Can anyone offer any advice?
I'll be using 4 inches of aggregate throughout the slab and 6 inches of concrete.
Some designs seem to have the DPC ontop of the aggregate and others have a floor screed ontop with a DPC under the floor scree (so much higher). Can anyone offer advice on protecting the edges of the slab? And how to connect the DPC in the black work to the DCP under the slab?
I've attached a cople of images as examples of the two ways that Ive found.
Thanks
