We are restoring a porch to its original appearance on a 100-year old house which has a stone foundation. The contractor wants to “lock” the new concrete foundation for the porch into the old house by pounding rebar into holes drilled into the stone. We are arguing over this because I don’t think the porch is going to settle much anyway, considering the age of the house and fill. And I also don’t think a few lengths of rebar will stop it if it does decide to sink (and the rebar may pull on the stone wall). Also, the thought of hammer drilling the stone and its old mortar joints is kinda scarey. Any suggestions would be appreciated.

stick to your guns. You are absolutly right. If the porch settles, it will pull on the house foundation and cause lots more damage. Unless there is a very good reason to do so, it is best to structurally porch and garage slabs from the main house foundation.
