Looking for advice. We have a slab that spans 8 feet from a new shop to an existing building. It requires about 10 feet of fill below the slab. We recommended a well graded, free-draining crushed gravel with a maximum size of 3/4" compacted to 100% standard proctor under the slab. Contractor came back and asked if he could fill all the way down with 40mm, running equipment over every lift to compact. I think hes trying to get away from the cost to test compaction. This slab has the potential for forklifts to run over it. Are we being unreasonable in sticking with our original spec?
