Garage Floors & Workshop Slabs
Poured 4" to 6" thick with thickened perimeter edge footings, tied rebar reinforcement, and a dense, hard power-trowel finish that sweeps clean and resists automotive fluid staining.
FLATWORK & FOUNDATIONS · BOUNTIFUL & SURROUNDING AREAS
Concrete slabs & foundations.
Monolithic slabs, detached garage floors, shop foundations, and structural utility pads poured flat, square, and built to your project's engineering specifications.
Base, thickness, reinforcement, drainage and use-after-pour instructions are set for each project. Any examples on this page are planning context, not a standard specification for every site.
Structural Integrity
The foundation of every solid outbuilding.
Whether you are erecting a detached two-car garage, building a custom workshop in your backyard, or preparing a level pad for a heavy storage shed, the concrete slab is the most critical component of the entire structure.
At Concrete Plus Contracting LLC, we treat foundation and slab work with absolute precision. An out-of-square formwork line or an uneven elevation complicates framing, door installations, and mechanical anchoring for the lifetime of the building.
We work from your architectural plans or project footprint, establishing thickened perimeter footings, grid rebar reinforcement elevated on chairs, and heavy vapor barriers to prevent subsurface moisture from penetrating your shop floor.

Accepted Slab Projects
Slab types we build across the Wasatch Front.
We specialize in residential outbuildings, detached workshops, and structural flatwork built to the agreed project specifications.
Monolithic Slabs with Integral Footings
Ideal for workshops, storage buildings, and pool houses. The floor slab and deepened perimeter grade beams are excavated, reinforced, and poured simultaneously in a single monolithic structure.
Structural Equipment & Utility Pads
Concrete utility pads can be discussed for the intended equipment. Manufacturer, structural and anchoring requirements must be established before the scope is finalized.
Slab Additions & Shop Extensions
Need to add an extra bay to your existing shop or extend a covered carport foundation? We review the existing concrete and any design requirements before specifying a suitable connection detail.
Installation Sequence
How our crew prepares and pours your slab.
Every step from subgrade compaction to power troweling is carefully coordinated to prevent settling and surface defects.
01
Site Measurement & Batter Boards
We establish 3-4-5 triangle squaring, check diagonal corners, and shoot benchmark elevations to check the planned slab levels and dimensions for future framing.
Key PriorityTrue 90° corners & exact building footprint
02
Perimeter Footing Trenching
We excavate to solid undisturbed native soil. For monolithic designs, perimeter trenches are dug to the designated frost and structural depth required by plans.
Key PriorityFirm footing trenches without loose soil
03
Gravel Compaction & Vapor Barrier
A 4"+ layer of crushed road base is placed and vibratory tamped. For enclosed shops, a heavy 10-15 mil polyethylene vapor barrier is taped to stop ground moisture migration.
Key PriorityMoisture barrier protection & base density
04
Formwork & Steel Rebar Grid
Rigid, braced wood forms are aligned with string lines. Deformed steel rebar (#4 or #5) is tied in an engineered grid pattern and lifted on concrete chairs to sit at mid-slab height.
Key PriorityProper rebar elevation and edge clearances
05
Concrete Pour & Laser Screeding
Concrete is placed, consolidated and screeded according to the project requirements, with attention to footings, reinforcement and the planned levels.
Key PriorityVoid-free consolidation around steel
06
Hard Trowel & Control Joint Sawing
As the concrete sets, our finishers make multiple passes with hand steel or walk-behind power trowels for a smooth, glassy finish, followed by timely saw-cut relief joints.
Key PriorityDense surface burnish & stress joint cuts
Planning Factors
Variables that shape your slab estimate.
We evaluate these practical site details to ensure your estimate is clear, transparent, and accurate.
Footprint Dimensions & Thickness
Total square footage, slab depth (4", 5", or 6"), and perimeter footing depth determine the required concrete volume and truck deliveries.
Structural Plans & Permit Specs
If your municipality requires engineered structural drawings, we build strictly to the plan's rebar spacing and perimeter footing depths.
Under-Slab Plumbing & Conduit
Any rough-in plumbing, floor drains, or electrical conduit sleeves must be verified and protected before base gravel is compacted and concrete placed.
Soil Bearing & Clay Conditions
Expansive Wasatch Front clays may need additional excavation and thicker crushed base to maintain structural stability under building loads.
Concrete Mixer Truck Access
Direct truck chutes allow faster pouring. If the slab is behind a home or down a tight alley, a concrete pump truck may be required.
Vapor Retarder & Insulation Needs
Heated workshop floors often specify rigid under-slab insulation and heavy-mil vapor retarders to meet energy and moisture codes.
Practical Questions
Slab and foundation questions, answered.
Here are common questions property owners ask when preparing for garage, shop, and outbuilding concrete.
What types of slab and foundation projects do you take on?
Our supplied scope includes detached garage floors, workshop slabs, monolithic slabs and related concrete flatwork. Share your plans so we can confirm the specific work and any structural requirements.
Do I need engineering drawings before getting an estimate?
Share the intended use, dimensions and any available plans for an initial discussion. Required structural design, permits and approved drawings must be established for the actual project before the construction scope is finalized.
Why is a vapor barrier recommended under an interior shop slab?
Moisture-control requirements depend on the building, floor use and approved plans. Tell us about the intended interior finish so the slab scope can account for relevant requirements.
What surface finish is best for an interior workshop or garage?
Discuss the intended use, coatings, moisture requirements and maintenance of the space. We can review suitable concrete finishes as part of the project scope.
How soon can we start framing walls on the newly poured slab?
Loading and framing dates must follow the project-specific release and care instructions. Weather, mix and construction loads affect the schedule; a fixed number of days cannot confirm readiness.
What information should I provide when asking for a quote?
Bring the proposed footprint, intended use, building plans, project location and any equipment manufacturer requirements. Access and the existing site surface also affect the estimate.
