Serious question, has anyone else had a backfill job go sideways because of the dirt?
I had to backfill a foundation for a new house in Cedar Rapids last week. The site boss gave me a load of what he called 'good fill dirt' and told me to just run the dozer over it. I did, but after the first big rain, the whole thing settled almost six inches in one spot. Turns out the dirt had way more clay than anyone said. Now I'm thinking you really need to check the material yourself, even if someone else says it's fine. What's the best way you guys test dirt on site before you start packing it down?
