Replacing Pocketed Joists-Old Structure
Replacing Pocketed Joists-Old Structure
(OP)
I have an old building that is being renovated. The first floor framing is essentailly all destroyed by termites and the entire first floor must be rebuilt under the existing structure. The existing floor joists are pocketed into the fieldstone foundation wall. We are going to put new joists in and they will not fit in the pockets or be able to bear on the sill plate. Typically I would put a ledger board into the foundation in this situation but the wall is fieldstone and the surface is very irregular, so there is no way to bolt a ledger flush. Options are 1. Parge the entire wall out 6" to get a flush surface 2. Parge only behind the ledger 3. Instal girders on columns in front of the wall 4. Any better ideas? Any ideas/tips on forming and parging a portion of the wall behind a ledger and drilling through the parging and into the wall for a ledger? Any better ideas?

This approach does not obscure the natural fieldstone...

You also indicated that new joists will not fit in the pockets which are present in the existing wall. You might consider LVL or steel studs which should allow you to use a member with less depth which might fit into your pocket.

Sneaky folk might scarf the sisters and the joist (tapering both in width), disguising the splice.
