I was in the crawl space of a house built about 30 years ago. The footing of the walls on two sides ended about 10 ft short of the connection with the perpendicular wall. There is what looks like a long CMU block that covers the span. I have seen shorter block used above doors and windows (lintel) and am familiar with bond beams normally used at the top of a CMU wall. I have never seen this set up before. The homeowner is nervous about the integrity of the structure. The house has been there for a while with no issues, but he wants some reassurance.
Anybody out there seen this before? I would appreciate some feedback.
