I had a home inspection done today and the inspector told me this was a first:
In the crawlspace there was a large box filled with concrete. It looks like this:
The builder was there at the end and he said they were not able to grind it down or remove it, so this is what they did.
The inspector says we should speak to an arborist to understand if this strategy is effective.
I've read around that the wood could rot and cause damage underneath. Now, this isn't holding up the structure obviously, but it still seems like a strange solution and I wondered if anyone has ever seen anything like this.
