New garage floors and garage floor replacement
What the building code requires
Under the 2015 International Residential Code (IRC), which Garland uses, the floor must be an approved noncombustible material, and the parking area must slope so liquids run to a drain or toward the main vehicle door. The IRC also sets a live load of 50 pounds per square foot in a garage, while a 6-inch slab itself weighs about 75 pounds per square foot.
Tear-out and a new pour
A replacement covers demolishing the old slab, hauling away the debris and pouring a new floor, and takes 2 to 4 days of work on average. Some jobs call for a structural engineer's report (about $550) or a geotechnical soil report (about $1,500) first.
Where the garage meets the driveway
The National Ready Mixed Concrete Association (NRMCA) uses isolation joints to separate driveways and patios from garage slabs, sidewalks and stairs so each part can move on its own. For a slab outside the garage, such as an RV or parking pad, see our concrete pads page; if the garage is part of a new building, see concrete slabs and foundations.

(945) 441-5958Slab thickness, base and vapor retarders
Thickness and base
The 2015 IRC sets a minimum of 3½ inches for a slab-on-ground floor, over a 4-inch base course of clean graded sand, gravel or crushed stone where the slab is below grade. Reinforcement only works when it sits at or just above mid-depth.
Vapor retarders
The IRC exempts garages and other unheated accessory structures from its vapor retarder rule. NRMCA still recommends a retarder at least 10 mils thick under interior slabs that will get floor coverings.
Joints
NRMCA spaces contraction joints 24 to 36 times the slab thickness, about 10 feet for a 4-inch slab and 15 feet at most, keeps panels square or nearly so, and cuts joints at least a quarter of the slab depth.
On Garland clay
Houston Black clay, the most common soil mapped in Garland, is rated "Very limited" in the USDA's Dallas County soil survey both for concrete driveways and sidewalks and for dwellings on concrete slab, because of high shrink-swell. Where a garage slab has sunk, mudjacking it runs $400 to $1,500 in 2026 Dallas-area figures.
- Contraction joint at least ¼ of the slab depth, 1 in. minimum (NRMCA)
- Sloped toward a drain or the vehicle door (IRC 2015)
- 3½ in. minimum floor on ground (IRC 2015)
- Reinforcement at or just above mid-depth
- 4 in. base course where the slab is below grade (IRC 2015)
- Houston Black clay, high shrink-swell (USDA)

(945) 441-5958Epoxy coatings, stain and polish
Coatings
Garage coating systems are typically epoxy-based, often with acrylic color flakes, and offer a wide range of design options. Nationally, epoxy runs $4 to $10 per square foot, polyurea $5 to $10 and polyaspartic $5 to $12.
Stain and stamped finishes
In national figures for garage floors, a single stain runs about $4 per square foot, a multi-stain finish $10 and stamped concrete $14.
Polishing the slab
A garage slab can also be ground and polished instead of coated. Garages are among the places where a stain-guard sealer helps, even though a densified polished floor needs no sealer of its own. Grits, sheen levels and costs are on our polished concrete page.

(945) 441-5958Epoxy, repair and curing questions
What type of concrete is best for building a garage floor?
The IRC puts garage slabs in its strictest strength category: at 28 days, 3,000 psi minimum where weathering is moderate and 3,500 psi where it is severe. The North Central Texas Council of Governments' recommended amendments to the 2024 IRC place the region in the Moderate class (a regional recommendation; confirm Garland's adopted table with the City). Around Dallas, 4,000 psi is often suggested for garage floors because of the shifting clay soil.
What is the downside of an epoxy garage floor?
Upkeep and application limits. Water-based epoxy may need a new coat every 3 to 5 years, while solid epoxy lasts 10 to 20 years, and epoxy should only go down between 60°F and 85°F with humidity under 85%. Normal highs at DFW Airport reach 95.6°F in July and 95.8°F in August. Quartz broadcast into 100% solids epoxy does add impact resistance not normally found with acrylic paint chips.
How much would it cost to epoxy a 2 car garage floor?
In 2026 Dallas-area figures, professional epoxy for a two-car garage of 500 square feet runs $1,550 to $6,190, and a standard garage averages $2,150 ($1,493 to $2,952). National figures are $1,600 to $5,800 for a 2-car garage, or $4 to $10 per square foot installed.
Should I repair or replace my garage floor?
Age and repair cost decide it. Replacing rather than patching is the usual advice once a concrete garage floor passes 20 years old, and full replacement also makes sense when repairs would cost more than half of a replacement. For smaller problems, national figures put sealing hairline cracks at $10 to $250, sealing leaking cracks at $150 to $500 and concrete leveling at $220 to $1,000.
How long before I can park on a new garage floor?
On a typical replacement timeline, the garage is unavailable during days 4 through 7 while the concrete cures. New concrete can support a car after 7 to 10 days if you keep off the edges, and it takes all normal traffic after 30 days.
