8 inch and thicker slab on grade - one or two mats of steel?
8 inch and thicker slab on grade - one or two mats of steel?
(OP)
I remember a thread here that included a statement that the USA Corps of Engineers requires two layers of steel reinforcement for 8 inch slabs on grade, where such slabs are designed to be reinforced, and I cannot find this requirement now.
Can a 8 inch slab on grade designed for forklift traffic have one layer of steel in the upper third and meet standards?
All help is appreciated - Thank you.

8" - 3/4" (top cover) - 2" (4-#4 bars) - 3" (bottom cover) = 2-1/4" clear theoretically. This probably would be closer to 1-1/2" once the guys step all over the top mat.
I wouldn't go to a double mat unless you had 10" thickness.

If it is designed as reinforced then I would use two layers for 12" or more.

I have done heavy slabs (8 to 12" thick) that support rack systems and have forklift traffic. Used one layer of bars (As = .005Ag) for crack control only. Worked fine.
