If I have a slab poured 7" thick with 4000PSI concrete with #5 aggregate on a minimum 6" compacted #53 stone base. Will this be sufficient enough hold a piece of machinery that weighs about 30,000 lbs. The equipment is a beam press and the estimated dynamic load is double the machine weight. The press has 4 feet that are 1 foot square. The soil below is listed as bearing capacity of 3,000PSF.
