For reasons of family sanity, what I'd like to do is build up the walls for the new conservatory in advance of taking the old (smaller) one down. However that means I cant pour the floor slab until later on.
Is it feasible and, indeed, satisfactory, to incorporate a strip (skirt) of 1200 membrane at dpc level, and later on, seal this with double-sided tape to the dpm I lay under the slab, creating a continuous dpm into the wall?
