This approach works only if existing joists run the right direction, of course. surveyor that one could use a cantilever beam or slab foundation, the PW-side footing of which would have to be 3m away from the existing PW foundations. The thermal break, with 30-inch stainless steel reinforcing bars protruding from the top on each side, is positioned at the edge of the slab and wire-tied to the interior steel. 0 . There is potentially significant torsion applied to the support beam at the line of facade, and the torsion is further amplified by the weight of the fascia. I live in an average sized semi detatched house. Cantilever slabs are typical one-way slabs. n. 1.
