How thick should a garage slab be?

Standard residential garage slabs are poured 4 inches thick with rebar or wire mesh. For heavy vehicles or workshop equipment, 5–6 inches with a rebar grid is recommended.

How long before I can use a new concrete slab?

Light foot traffic after 24–48 hours. Passenger vehicles at 7 days. Heavy equipment or vehicles after 28 days — full design strength.

Q: How much does a concrete slab cost in St. George?

Residential concrete slabs in St. George typically run $5–$9 per square foot depending on thickness, reinforcement, and finish. A standard 400 sq ft garage slab runs $2,000–$3,600. Call for a free on-site estimate.

Q: What PSI concrete do you use for slabs?

We use 3,000–4,000 PSI mix for residential slabs. Higher PSI concrete is harder and less susceptible to surface wear under foot traffic, tire loads, and UV exposure in Southern Utah.

Q: Do concrete slabs crack?

All concrete slabs eventually crack. Control joints are cut into the slab after pouring to direct cracking to predictable, straight lines rather than random surface cracks. Proper base prep and reinforcement minimize uncontrolled cracking significantly.

What We Pour

Concrete Slabs for Every
St. George Project

A concrete slab is one of those things where the preparation matters more than most people realize. The strength of the finished slab depends on the quality of the compacted base beneath it, the correct reinforcement, the right mix for desert conditions, and curing that protects the concrete through St. George's heat.

We pour residential and light commercial slabs for a wide range of uses — from simple garage floors to covered workshop slabs, storage pad areas, and RV storage structures. Every slab gets proper base prep, the right reinforcement for the load it will carry, and control joints to manage cracking predictably.

Common Slab Types

Garage Slabs

Standard 4" residential garage floors for 1, 2, or 3-car garages. Reinforced and finished with a broom or smooth surface depending on preference.

Workshop Floors

Heavier slabs for workshops, hobbyist spaces, and light commercial. Often 5–6" with rebar to handle machinery and equipment loads.

Equipment Pads

Generator pads, HVAC equipment, outdoor mechanical units. Sized to spec, properly isolated from the main structure where needed.

Storage Slabs

Covered storage buildings, carports, and outdoor storage pad areas. Sloped for drainage, reinforced for load.

Common Questions

Concrete Slabs
in St. George — FAQ

How much does a concrete slab cost in St. George?

Residential concrete slabs in St. George typically run $5–$9 per square foot installed, depending on thickness, reinforcement, finish, and site preparation. A standard 24x24 ft garage slab (576 sq ft) usually comes to $2,900–$5,200. Call 801-640-1788 for a free on-site estimate.

How thick should a garage concrete slab be?

Standard residential garage floors are poured at 4 inches thick with wire mesh or rebar. If you're parking heavy trucks, storing RVs, or running machinery, go to 5–6 inches with rebar grid. Base preparation quality matters as much as thickness — always compact before pouring.

What PSI concrete do you use for slabs in St. George?

We use 3,000 PSI mix for standard residential slabs. For workshop floors, commercial applications, or high-load storage, we step up to 4,000 PSI. Higher strength concrete is harder and more resistant to surface wear, particularly important in Southern Utah's UV-intense environment.

Why do concrete slabs crack and how do you prevent it?

All concrete shrinks slightly as it cures, and cracks under temperature changes. Control joints are cut into the slab to create intentional weak points — directing any cracking to straight, predictable lines rather than random surface cracks. Proper base prep, correct water/cement ratio, and adequate reinforcement minimize uncontrolled cracking significantly.

When can I use my new concrete slab?

Light foot traffic after 24–48 hours. Passenger vehicles at 7 days. Heavy trucks, forklifts, or equipment after the full 28-day cure. The surface looks and feels firm well before full strength — don't rush it under heavy loads.

Do you pour slabs for new construction in St. George?

Yes — we work with homeowners, builders, and contractors on new construction flatwork including garage slabs, shop floors, and accessory structure pads. Call or email to discuss scope and scheduling.
