DAE think building a shed with a concrete slab is a huge mistake?
My neighbor Bill poured a 12x16 slab in his yard in Boise two summers ago and now the whole shed floor is a cracked mess near the door. He spent $900 on that concrete and the frost heaves it every single winter here. I built mine on pressure treated skids sitting on 6 inches of gravel, and after 4 years it's still dead level. Why does everyone keep copying the slab thing when a gravel pad costs $150 and drains way better?
