Slab Thickness 4" or 6"
Feb 04, 2010· The fill in the building was 18" of stonedust pounded down to where the concrete trucks left no tracks deeper than the tire tread. The other was a paint shop that specialized in sign/logo painting on trucks, heavy equipment, cranes, etc. That was 4000lb mix with wire. I visited these slabs two years later they showed no cracks.
