Slab on grade for office building
Slab on grade for office building
(OP)
I've typically used 5" reinforced slabs on grade for all lightly loaded commercial structures (offices, etc. No rack loading, forklifts, trucks, etc.)
I'm looking at a set of drawings that specifies 4" for this same type of condition. I've looked around for guidance as to whether there is a recommended thickness for a lightly loaded slab, but apparently my google-fu is lacking. Lots of information for heavily loaded slabs, of course.
The 4" doesn't seem wrong - just different. Does that thin of a slab generally have a problem with curling?
What are you used to using and do you have a reference material that you can point to?

I've always felt that the thinner the slab on grade, the more important precision in base prep becomes. The skill of the sub preparing the base should be considered, as variations in the base elevations impact thinner slabs more adversely.
