Reducing Concrete in Slab
Is there a way I can reduce concrete usage in this slab?
9’x13.5′ slab. 18″ frostline. 1.5″ rockwool comfortboard 80 (R6). My monolithic slab calculations are coming out to about an 8 yard order for a 121.5 sq ft slab. Is there a better way to do this?
If I reduce the slab depth, I have to wait until spring to pour it. If I don’t go monolithic, costs will be higher since it will require 2 trips for the truck.
I’ll be building the formwork, bending/cutting rebar, placing rebar chairs, and finishing the concrete myself.
