A concrete slab for a shed, shop, garage, or equipment pad has to be matched to its load, and built on a base that stands up to Idaho's clay soil. Here is what slabs cost in the Pocatello area, the right thickness and reinforcement for different uses, and the prep that keeps a slab from settling.
A concrete slab in the Pocatello area typically runs about $6 to $10 per square foot installed for a standard utility slab. A 400 square foot shed or shop pad often lands around $2,400 to $4,000, with heavier, thicker, or reinforced slabs costing more. What drives the number:

Utility slabs vary a lot depending on whether they support a light shed, a shop, a garage, or heavier equipment. Thickness, reinforcement, and sub-base prep should fit the actual use rather than assuming every slab is the same. A pad that is fine under a garden shed can fail under a metal building or a lift, so it is worth stating the real intended use up front.
Even a simple pad gets more complex if access is tight, grading is uneven, or the slab ties into an existing structure. Over Idaho's expansive clay, proper excavation, a compacted gravel base, and reinforcement are what keep a slab from settling and cracking. Ask what base prep and reinforcement are included so quotes are comparable.
Typically $6 to $10 per square foot for a standard utility slab. A 400 sq ft shed or shop pad often runs $2,400 to $4,000, with thicker reinforced slabs costing more.
Four inches for sheds and light use, five to six inches for garages and shops, and more with rebar for heavy equipment. Match the thickness to the actual load.
Most utility and structural slabs benefit from rebar or wire mesh, especially over clay soil, to control cracking and hold the slab together as the ground moves.
Excavation, a compacted gravel base, and often a vapor barrier for enclosed buildings. Compaction is what prevents settling and matters as much as the concrete.
