C. On top of the rebars lay wire mesh of 2inch.
D. Reinforce the edges by at least double the thickness of the slab with same width ( edge)
E. Concrete at its thinnest should not be less than 4"" with the reinforcement bars and wire mesh in the middle.
F. Slope each section at 1/2 inch per foot of width ( for rain drain.
G. Tarpaulin to cover the drying/dried grains should cover to about about a foot less than the width valley to valley.
The tarp is a precautionary measure in case the rain starts to Dro and you don't have enough time or manpower to bag the grains.
