In a small room beneath my front porch there are some large continous cracks. At some points they are 1/2" + . The house was built in 1930; the walls are block and the floor of the porch is poured in place concrete. You can see the porch in the picture, and the room in question is below that (above grade).
The exterior stucco was repaired 2 yrs ago, and there are no cracks translating through at this point.
So, what are my options? I assume there could be tie rods tying it all back together ($$$$$) or I could patch it with some sort of patch ($). Any suggestions?
