Garage and utility slabs sized for how the space gets used.

Flat, durable slabs for garages, shops, additions, and utility spaces: sized for use, not for the bare minimum spec.

The reality

What homeowners run into with garage slabs.

A slab that is too thin, uneven, or poorly planned turns a garage, shop, or addition into a long-term headache. Most slab failures trace back to base prep or thickness, not the concrete itself.

The [Your Concrete Company] plan

Scoped before the first form goes down.

[Your Concrete Company] scopes the slab around the actual use: vehicles, lifts, tools, addition loads, or workshop layout. Thickness, reinforcement, and finish all match the use case before pour day.

Start a slab estimate

A slab spec you can stand on.

Garage and shop slabs are structural elements. The spec reads like one.

4-6 in Slab thickness

Sized to the load: daily drivers, lifts, racks, or an addition above.

4,000 PSI Mix standard

Air-entrained mix specified for Colorado freeze-thaw cycles.

10 mil Vapor barrier

Sheeting under the slab keeps ground moisture out of the finished space.

28 days Design strength

Drivable in about a week; the mix reaches its rated strength near day 28.

What's included

Carried on every slab pour.

The non-negotiables underneath garages, shops, and additions.

Use-case sizing

Pour spec matched to vehicles, equipment, or addition loads.

Proper base prep

Sub-grade compaction, vapor handling, and reinforcement planned in.

Clean form work

Straight forms, square corners, and edges that line up with the structure.

Finished surface

Smooth-troweled or broomed finish, chosen for how the space gets used.

In writing

What the written slab scope locks in.

Before pour day, every line below is already decided and priced.

Dig-out and haul-off of soil or the old slab, with depth stated
Compacted base with material and lift depths called out
Vapor barrier grade and overlap, under the full footprint
Reinforcement type, spacing, and placement, set before the truck arrives
Thickness and mix matched to vehicles, equipment, or the structure above
Finish and joint plan including the cure schedule for first vehicle use

Flatness is a spec

Flat is measured, not eyeballed.

Cabinets, lifts, and toolboxes all assume the floor is true. [Your Concrete Company] screeds to the structure, checks the plane before finishing, and cuts joints where the slab math wants them, not where they are convenient.

Square to the structure: Forms set off the foundation lines so framing lands where the plans say.
Moisture handled below: Vapor barrier and base drainage planned before the pour, not patched after.
Joints by the panel math: Saw cuts laid out from slab dimensions so cracks have somewhere to go.

What moves the price

Four inputs set a slab estimate.

A slab estimate is mostly decided below the surface. These are the inputs that move it.

Footprint & thickness

Square footage times depth is the concrete itself; heavier use means a thicker section.

Excavation & base

Dig-out depth, imported base, and compaction passes scale with the existing ground.

Reinforcement & vapor spec

Rebar or fiber, barrier grade, and edge details follow the load the slab must carry.

Surface & joints

Smooth trowel for shops, broom for traction, plus the saw-cut joint plan.

Dollar figures come from the walkthrough, in writing. These are the levers that set them.

Square to the framing. Flat to the tool. Ready for the build above it.

A slab is the one trade everything else stands on.

Slab questions

Slab answers, straight to the spec.

Loads, timing, and builder coordination: what slab projects come down to.

Are garage slabs different from patios?

Yes. Garage and shop slabs usually need more attention to load, thickness, access, and the surrounding structure. The spec is closer to a structural element than an outdoor living surface.

Can a homeowner request a slab estimate before final plans are complete?

Yes, but final dimensions and use details lock in the quote. We can start the conversation early and refine the estimate as the plans firm up.

Do you coordinate with a builder or framer?

When the slab supports a structure, the install is sequenced with the builder so the foundation is ready when framing arrives. We bring our plan to that conversation, not the other way around.

When can vehicles park on a new garage slab?

Light foot traffic is fine within a day or two. Vehicles typically wait about a week, and the mix keeps gaining strength toward its design rating near day 28. The handoff sheet gives you the exact dates for your pour.

What makes one slab estimate higher than another?

Footprint and thickness, how much excavation and imported base the ground needs, the reinforcement and vapor spec, and the finish. Each is a separate line in the written scope, so a thicker or better-reinforced slab is a visible choice, not a surprise.
