Charlie R Posted January 24, 2011 Report Share Posted January 24, 2011 Had a good one today, a small one story ranch/cottage with a basement. Someone built an addition on the back, but it looked like they just built it on the concrete porch patio slab. Sure enough, I start to tunnel under, never hit anything but dirt.

Bain Posted January 24, 2011 Report Share Posted January 24, 2011 I see this several times a year. It's wrong, and I make an issue out of it, but I've never seen any signs of movement or other deleterious problems caused by the lack of footers. Typically, the new/old roof connections are atrocious and the valleys contain lots of goop. Quote Link to comment Share on other sites More sharing options...
AHI in AR Posted January 25, 2011 Report Share Posted January 25, 2011 I see similar additions around here also. Perhaps surprisingly, most often there aren't big problems. Frost heave generally isn't an issue locally, and the soil in most areas I work in is pretty stable--not a lot of plasticity where moisture changes are an issue. Farther north or in areas with expansive soil and you're on your own! Quote Link to comment Share on other sites More sharing options...
John Kogel Posted January 25, 2011 Report Share Posted January 25, 2011 I would call that a "temporary addition, that was probably built without a permit." I will point out that the wall is sitting on the slab and it will rot when people stop maintaining the caulk. And we know they will. Quote Link to comment Share on other sites More sharing options...
