Raised floor to slab on grade
Raised floor to slab on grade
(OP)
I have a client who has an existing wood raised floor foundation. The joists bear on top of the concrete stem wall. They want to do a portion of their addition as slab on grade. This means the concrete slab on grade will butt up right against the existing wood sill plate, joists, and floor sheathing.
Does anyone know a way of protecting these joists from moisture? Will flashing be enough?
Thank you.

RE: Raised floor to slab on grade
In my opinion any traditional flashing material is likely to fail. I would use a combination of a hydrophobic elastomeric/tarry material PLUS a traditional flashing. Or potentially a plastic flashing...
The CCA and other pressure treatments tend to each flashing metals. It is a problem we are seeing more and more, particularly in low rise condominium developments.
