East Central wisconsin | Good question Brian. My first thought is they knew they were spanning a crawl space when they poured that. I can't imagine it not having some sort of rebar? But even still, with everything getting heavier, delivery trucks etc. At some point it could be a surprise problem for a unsuspecting truck driver. So, maybe curb the small area off, and put some benches or picnic tables there. Or cut the concrete, drop it in the hole, then fill it level with stone and gravel and call it good? Good luck. | |

How far can you bridge concrete?
