When remodeling an old house, knowing exactly where the house is structurally makes sense. In this video, Matt Risinger, takes us to a 1915 bungalow that is the setting of a whole house interior remodel. With a 100-year old home, however, do we really know that the structure is completely sound? From the front porch to the back of this home, the lot slopes approximately nine feet. There is basement space, but its structural integrity is unknown. After digging test holes in the back section, it's discovered that a structural slab is in that area, poured long ago, and it doubtfully contains rebar or steel. Once a small portion underneath that slab is excavated, the exact thickness of the structure can be found. The same process will repeat on the high side of the structure. Finally, inside, cutting a couple of holes in a closet in the structure, large enough to have a camera snake under, the floor joist system and post conditions will be available. Discovery includes 2 x 10 joists and a 14 ½' span on this portion of the house. There is a 4 x 6 center beam and 2 x 10 joists on the other side with a 15 ½' span. They're 24" on center. There are also telephone poles to support the house. Most likely", there were cedar posts in there that probably had rot and no concrete underneath them. The poles could either have been support posts or rammed in to stabilize the house. There is a 4 x 6 beam running across the section and 2 x 10s on top. The 2 x 10s seem over-spanned. The results of investigating the back-yard section of the slab, it does not look like there is rebar of steel, but some mesh was used when it was poured, which really is not of structural benefit. The structural engineers will soon be there, taking measurements and figuring out the plan going forward.
