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