Curtis,
A few years back we built two bins that shared a middle wall. The large side is 20' x 24' and will hold about four full loads of topdressing. The smaller bin is 12' x 24' and will hold two loads of divot mix. These were built using a 10" slab full rebarred with vertical rebar for the wall every 5'. The wall is block, with horizontal rebar every two rows. The wall is 7 rows high and poured solid. We had a test last week when our sand delivery guy back into the wall. The upper row had a few blocks knocked lose with some good cracking, but the wall stayed upright and is still solid. My only wish now is that I had built more than two bins. It seems we are always needing somewhere to put a load of gravel or bunker sand. Except the pad, we built these in-house for under $2,500.
Last year, I had our concrete company come build me another one at our other shop. This one is 20' x 20' on a 10" slab and similar rebar setup. Except this bin had the walls poured 10" solid , 4' high, instead of blocked. This bin cost me slightly more, but was a steal at $3,400.
