Slab-on-grade exterior threshold detail
I am beginning a DER of an old commercial building – our new workshop – in zone 6, northern NH. The framed floor on piers is first being upgraded with poured footers, CMU stemwall, and a slab on grade. EPS will be beneath the slab and along the inside of the stemwall. The wall is a deep double stud with an air barrier paper on the inner wall. The gap in sill plates where the exterior door will go is a detail I am unsure of how finish. How should the 8″ block, 3″ EPS, and slab floor be flashed and sealed with the door frame and threshold? Euro-style window install details often say “doors are similar”, but I have never found a good diagram for this application.
