NE Iowa | We were always too cheap and we only ever poured 4" thick for cattle feeding floors. Only on them with skid steer and tractor / manure spreader. 4000 psi concrete with the 6x6 wiremesh is what we used most of the time. We made sure to have a good base and spent a lot of time making sure the depth was exactly 4" everywhere. Some of these floors are 50 years old and some minor cracks but still get scraped weekly. For feeding floors I would rather have a bigger pad at 4" then going 6". In your case 40'x50' at 6" thick or 50'x60' at 4" would be the same amount of concrete. I would take the 50x60 at 4" any day. | |
