Dump and Spreading Screening Sand. Prepping for the remaining 11 loads: variables to consider: truck size, belly dump vs. end up, arena size, gate size, ground conditions (you don’t want a 15 ton semi loaded with 22 tons of sand stuck in your backyard), space needed to turn, traffic flow, etc, etc, etc.
Total 19 loads of screened sand for a 180x130ft arena.
