Thickened-edge slabs and footings for workshops, detached garages, and equipment buildings - engineered for the loads you actually put on them.

Shop Slab Specialists

A Shop Floor That Takes The Load

A shop slab is not a patio with a building on it. Lifts, presses, loaded trailers and pallet jacks all put point loads on concrete that a 4 inch residential pour was never designed to carry, and the failure shows up as cracking around the exact spot you use most.

We pour thickened edges and interior footings where the equipment actually sits, size the slab and steel to the loads you describe, and detail the moisture barrier so the floor is not sweating under a toolbox two summers from now.

  • Thickened edges and interior pads under lifts and presses
  • Slab thickness and steel sized to your equipment loads
  • Vapor barrier and base prep for San Antonio clay
  • Anchor bolt and sleeve placement set before the pour
  • Broom, trowel, or sealed finish depending on the use
  • Aprons and approach slabs poured at the same time

4

Pour & Finish

Quality concrete is poured, leveled, and finished to your chosen style. Control joints are cut precisely to prevent random cracking.

Investment

What Affects Shop Slab Cost

Factors That Determine Your Price

Every project is unique. Here are the main factors that influence your total investment:

  • Total square footage - larger projects benefit from volume pricing
  • Site preparation - demolition of old concrete, grading, drainage work
  • Finish type - broom finish, stamped, exposed aggregate, or decorative borders
  • Concrete thickness - standard 4-inch vs heavy-duty 6-inch for trucks or RVs
  • Access and slope - hillside or tight-access sites add complexity

Shop Slab FAQ

Common Concrete Questions

What owners ask before pouring a shop or garage floor.

For light workshop use, 5 inches with fiber or mesh is usually enough. Add a two-post lift, a press, or loaded trailers and we go to 6 inches with rebar and thicken under the equipment. We size it to what you tell us will sit on it.
Yes, and it needs planning before the pour, not after. Most two-post lifts want a minimum thickness and a specific cure strength under the posts. Send us the lift model and we will detail the pad to the manufacturer spec.
If you are storing tools, welding, or ever want to coat the floor, yes. Without one the slab wicks ground moisture and you get a damp floor, rusting tools, and coatings that peel.
Yes. Send the anchor bolt plan from the building supplier and we set them in the wet pour to the template, which is far more accurate than drilling afterwards.
Foot traffic at 24 to 48 hours, vehicles at 7 days, and heavy equipment at 28 days when the slab has reached full design strength. We will give you the dates in writing.
