Wire Mesh for Reinforcing a Slab on Grade

I am soon to pour a 756 sq. ft. mono slab on grade with turned down footings in PNW 4C.

Heyou supply professional and honest service.

Sturdy subsoil but will be adding compacted crushed rock, Poly barrier, 4&#; EPS, then a 4&#; slab. However, the slab will not be the finish floor &#; 3/4&#; T&G cdx with wood floor finish. Footings are to seismic code here with two #4 rebar at top and bottom of 12&#; wide footing.

My main question is do I need to worry myself with welded wire mesh or even the fiber mesh additive if i won&#;t be seeing any cracks that form? ie. is it structurally sound enough to not mess with flooring above?

I have gleaned info from similar threads and plan to compact base well and wet concrete after pour to help prevent cracking.

Thanks!

I am building a patio home (concrete slab) and they will soon be pouring the foundation. One concrete worker that I know suggested that they should use 8 gauge mesh vs. 10 gauge mesh. I don&#;t know much about concrete to know if that would be a good idea for the extra cost or not. Approx. sq. feet. Any help would be appreciated.

This is my first post with FineHomebuilding. Looks like a great place to get some answers.

Thanks.
