Concrete over above-grade rubble foundation
I was visiting a home the other day, primarily in search of no/low cost energy improvement opportunities, when the customer asked about insulating his rubble foundation. I recommended ccSPF of course with a poly lining on the floor and up the sides of the walls to create an air and water tight assembly.
Upon leaving, I noticed that the exterior of the above-grade foundation seemed to be covered by what appears to be concrete. I couldn't quite tell as most of his foundation was covered by snow. From the interior however this rubble foundation runs right to the sill, and I couldn't see any evidence of a poured material.
Has anyone else seen something like this? Is it a common practice? I didn't think so, but I could be wrong. It makes me wonder then if its still worth adding spray foam to the interior, since the majority of the leakage would have been from the above grade. Thoughts?
