Why Choose a Concrete Patio for Your St. Augustine Home?
A custom-poured concrete patio is the premier choice for homeowners in the St. Augustine area looking to upgrade their outdoor living spaces. Unlike wood decks that rot from Florida's extreme humidity or loose paving stones that shift and allow weeds to sprout, solid concrete offers vastly superior longevity and hassle-free maintenance.
- Weatherproof Longevity: Concrete easily handles intense Florida UV rays and coastal salt air without warping, splitting, or fading over time.
- Versatility & Function: A professionally poured slab provides a flawlessly level, flat foundation that is ideal for patio furniture, heavy grills, hot tubs, or heavy pergolas.
- Low Maintenance, High Value: Our patios require zero routine staining, tightening, or tedious weed-pulling, saving you significant time and money on upkeep year after year.
We pour our patio slabs with a structural mix rated at 3,000 to 4,000 PSI, ensuring your new outdoor space handles localized structural loads and seasonal climate swings effortlessly.
Our Concrete Patio Building Process
To ensure your backyard patio looks immaculate and resists sinking over time, the Concrete Commandos crew follows a disciplined, professional installation timeline:
1. Site Prep & Grading
We begin by safely removing any old patio material, grass, or loose soil. The footprint is then precisely graded with a slight slope away from your home’s foundation to ensure proper water drainage during heavy downpours.
2. Compacted Gravel Subbase
We mechanically pack a solid gravel and sand base layer beneath the formwork. This essential foundation stabilizes St. Augustine's loose, sandy soil and prevents the concrete patio from tilting, settling, or pooling water.
3. Wire Mesh or Rebar Reinforcement
We install a locked grid of steel rebar or heavy-duty wire mesh throughout the pour area. This internal structural reinforcement adds vital tensile strength, keeping your patio safely locked together and resisting stress cracks.
4. Concrete Pouring & Finishing
We pour our premium concrete mix to a uniform thickness of 4 inches (or thicker depending on structural load needs like hot tubs). Our crew applies your choice of finish—such as a clean broom texture for slip resistance—and cuts precise control joints to guide natural movement.
5. Curing & Post-Pour Clean-Up
We carefully monitor the early curing process so the slab dries evenly under the sun. You can walk on your new patio after 48 hours, and place heavy outdoor furniture on it after 7 days. We finish by stripping the forms, cleaning up the perimeter, and leaving your yard pristine.
Reinforced Patios Built for the Florida Coast
Northeast Florida weather and sandy coastal soil require specific structural practices to prevent slab failure. That's why we reinforce every single patio slab with embedded steel and use properly rated mix designs tailored for local soil profiles.
- Slabs Designed for Backyard Weight Demands: Planning a heavy brick fireplace, a fully loaded outdoor kitchen, or a large hot tub? We customize your patio’s thickness, subbase compaction, and internal steel grid to make sure your concrete holds up perfectly without cracking under localized stress.
- Subgrade Compaction Stops Soil Shifting: Heavy seasonal downpours can easily sweep loose coastal sand out from under weak slabs. Our deep-compacted subbase ensures absolute stability, keeping your patio completely level and stable for decades.
- 3,000–4,000 PSI Mix for Maximum Wear Resistance: We pour high-quality, verified PSI mixes that guard against surface pitting, scaling, and premature degradation caused by tracking in pool water, chemicals, and outdoor traffic.
- Clean Control Cuts Prevent Wild Cracking: Concrete naturally expands and contracts with shifting temperatures. We saw clean, straight lines into the slab, directing natural movement invisibly along pre-planned joints instead of letting random cracks show across your patio surface.
New Patios, Replacements & Extensions
We build and restore outdoor living spaces for all types of residential needs:
New Installations: Perfect for turning a plain grass backyard into a functional, clean outdoor living room. We handle everything from design layout and permitting to the final finish.

If your old patio is badly cracked, uneven, or holding standing water near your house, we will safely break it up, haul away the old concrete, remedy the underlying drainage, and pour a reinforced new slab.
Extensions:
Already have a small patio slab but need more space for seating or a grill? We will expand your layout, seamlessly matching the slope, height, and finish of your existing concrete.
Custom Patio Styles and Finishes Available
We focus on practical, high-performance finishes that look incredible and hold up beautifully year after year.
Standard Gray Broom Finish: A finely textured, classic surface that adds vital traction and eliminates slip hazards when the patio gets wet from rain or pool splashes.
Stamped Concrete Patterns:
High-end decorative impressions that mimic the luxurious appearance of natural stone, slate, cobblestone, or brick at a fraction of the cost.

Frequently Asked Questions About Concrete Patios in St. Augustine
How thick does a standard backyard concrete patio need to be?
Most residential concrete patios are poured at a standard thickness of 4 inches. This depth is excellent for standard foot traffic, patio furniture tables, and standard grills. However, if you plan to install a large luxury hot tub or an expansive brick outdoor kitchen, we will engineer specific sections to be 5 to 6 inches thick with extra rebar grids to handle the heavy weight load safely.
Will a new concrete patio crack under the hot Florida sun?
All concrete shrinks slightly as it cures and naturally moves with seasonal temperature changes. To prevent random, unsightly cracks from running wildly across your new patio, our crew strategically saws clean, straight control joints into the slab. This ensures that any natural shifting occurs invisibly along those pre-planned lines, keeping the surface looking pristine.
How soon can I walk on my new patio and put my furniture back?
You can safely walk on the fresh concrete surface approximately 48 hours after our crew finishes the pour. However, you should wait a full 7 days before dragging heavy metal patio furniture, large grills, or heavy stone planters back onto the slab to allow the mix to reach proper structural strength.
Will a concrete patio be slippery when it rains or when stepping out of a pool?
Not when it is poured by professionals. We apply a premium, light broom finish to our standard gray patio slabs. This technique leaves a subtle, clean texture that dramatically maximizes foot traction, ensuring the surface remains slip-resistant and safe even during heavy summer downpours or around pool decks.
Can you match my new patio extension to my existing old slab?
While we utilize identical finishing and edging techniques, fresh concrete inherently cures to a lighter color than older, weathered concrete that has been exposed to elements and dirt for years. To achieve a perfectly seamless and uniform look across old and new sections, we highly recommend a full concrete resurfacing overlay or utilizing a decorative stamped concrete texture across the entire connected footprint.
Do I need a building permit to pour a backyard patio in St. Augustine?
In many areas of St. Johns County, a residential building or zoning permit is required to verify property line setbacks and storm water runoff compliance. Don't worry—our team handles the local permitting process from start to finish, ensuring your patio is completely code-compliant.
