A shop slab price is mostly decided before any concrete shows up. The pad, the base and the thickness are what make one quote double another. Here is what goes into it.
What drives the cost
- Size and thickness. Square footage times thickness is the concrete volume. Shops that hold trucks, lifts or equipment need more thickness than a garden shed.
- The pad. A flat lot needs a little grading. A sloped lot needs cut and fill, compaction and sometimes retaining. This is where the numbers spread.
- Gravel base. Depth of base rock and compaction. Skimp here and the slab cracks.
- Reinforcement. Rebar or wire, and thickened edges or footings for the building.
- Finish and extras. Aprons, approaches, floor drains, saw-cut joints and finish type.
- Access. Whether the mixer truck can reach, or a pump is needed.
Before or after the building
Steel buildings usually need the slab or footings first. Many pole barns go up first and the floor gets poured inside. We plan it with your builder so nobody is waiting.
How to get a real number fast
- Building dimensions and what will be parked inside.
- The address and a few photos of the spot.
- Your builder's footing or anchor requirements if you have them.
