The concrete itself

The ready-mix is a smaller share of the price than most people expect. Angi's Orlando figures put fast-setting concrete at about $130 a cubic yard and high-strength at $155. Short loads cost extra: $40 to $60 per yard under a full truck. Labor runs 40 to 60 percent of a slab job in the Orlando area (Angi).

Ground, termite treatment and access

Fill to raise a low lot, compaction, the termite treatment and vapor retarder for a building slab, and how far the truck can reach all sit outside the per-foot rate. A slab the chute can't reach needs a pump or wheelbarrows. The sandy soil guide and termite pretreatment guide explain the prep.

Worked example

Pricing a 14 by 20 foot slab for a backyard workshop

In this example a homeowner in St. Cloud wants a 14 by 20 foot slab for a prefab workshop. At 4 inches the slab takes about 3.5 cubic yards, less than a full truck, so a short-load fee is likely, and the shed maker asks for a thickened edge where the walls sit.

A workshop is a building, so the permit and the termite treatment come before the pour. The price lands near the typical figure on a dry, open lot and higher on a low one that needs fill.

280 sq ft at the Florida typical, $7.93 per sq ft	about $2,220
Florida range, $5.38 to $12.83 per sq ft	$1,510 to $3,590
Concrete needed at 4 in: about 3.5 cubic yards (at $130 to $155 per yd, Angi)	$450 to $540
