Rock siding on independent footing? will it work?
Rock siding on independent footing? will it work?
(OP)
Hi,
I've got a project with rock siding on the foundation. Half of the basement is exposed, and half in mostly below grade. The exposed section will have rock siding all the way to the footing. We are trying to decide if for the unexposed sections we can compact the soil in lifts and create a independent footing for just the siding just below the frost line to keep from siding these section to the footing (expensive). The concern of course is differential settling. Can we expect similar settling? Is this risky, has anyone done this before successfully?
We can't anchor the rock to the basement because it has 7" of Foam on the side, and no serious thermal bridging is allowed. There are however fiberglass rods every 2' feet connecting the rock to the concrete that keep shear between the wall and rock to a minimum.

By the way, where is your waterproof membrane? I like basements to be dry, whether or not the temperature is well controlled.

I would not build the footing at the location you have shown, too much chance for settlement on disturbed fill. I would make sure the foundation for the stone veneer is at the same level as the structure. Additional insulation could be placed on the exterior of the block wall located below grade to minimize any thermal transfer.
With the amount of insulation on your detail, especially underneath the slab-on-grade, I presume this is being built in an area with a significant frost depth or perhaps permafrost (or perhaps this is a speciality type building)? Adfreezing on the exterior of the block wall supporting the veneer should also be considered.
