Concrete Services in St. Johns, FL

St. Johns grew fast. The area went from a loose collection of places like Fruit Cove and Switzerland to one of the busiest suburbs in the Jacksonville metro, and the name itself only became official with the Postal Service in 2005. That growth shapes almost every job we quote here.

Upgrading Builder-Grade Concrete on Newer Homes

Communities like Julington Creek Plantation and RiverTown were built in phases, and the concrete that came with each house was sized to the lot plan, not to how people live. Here is how we approach the most common upgrades.

Widening a driveway for a third car or a boat

The usual request is a strip added to one side of the driveway so two cars and a trailer fit without anyone parking on the grass. We saw-cut a clean edge on the old slab, drill and epoxy #4 rebar dowels into it at roughly 24-inch spacing, and pour the new section at the same 4-inch thickness (5 inches where a boat or work truck will sit).

The dowels keep the new strip from settling separately from the old one. We match the broom direction, run a control joint along the seam so any movement shows up as a straight line, and slope the addition the same way the original drains.

Extending the rear patio past the screen enclosure

Many St. Johns homes have a small covered lanai slab and a screened area that barely fits a table. We extend the patio out into the yard, pin it to the existing slab, and keep a slope of about 1/8 to 1/4 inch per foot away from the house so afternoon storms run off instead of toward the slider.

If you plan to add a screen enclosure or pergola later, tell us now. We can thicken the slab edge where posts will land so the next contractor is not anchoring into a thin 4-inch edge.

Walkways, side yards and trash-can pads

Side yards on tight lots turn to mud fast in the rainy season. A 3- to 4-foot walkway down the side of the house, plus a small pad for trash and recycling bins, clears up a surprising amount of daily mess. We keep walkways below the slab of the house and pitch them toward the yard.

St. Johns County Permits and HOA Approvals

Because St. Johns is unincorporated, your permits come from St. Johns County rather than a city hall. Most neighborhoods here also have an architectural review board, and we plan around both.

When the county right-of-way is involved

The section of driveway between the sidewalk and the street, plus any culvert under it, sits in the county right-of-way. St. Johns County's Right-of-Way Division notes that an approved building permit already covers the driveway and culvert connection on new construction. When you are replacing or widening that apron on an existing home, a separate driveway/culvert permit applies, and the county wants a site drawing showing the exact driveway location.

A few county rules we design around:

• Pavers can be used for driveways in the county right-of-way, but not for sidewalks.
• The public sidewalk crossing your driveway cannot be altered without written authorization.
• The end of a culvert must sit at least five feet from the corner property line.

HOA architectural review

Most HOAs want to see a drawing before a driveway widening or patio extension, and some limit finishes or colors at the street. We provide a simple site sketch with dimensions, thickness and finish so you can submit it, and we do not schedule a pour until the approval letter is in hand.

What we put together for your submittal

Review boards and the county both move faster when the paperwork is complete the first time. For a typical St. Johns driveway or patio project, we prepare:

• A site sketch showing the new concrete, property lines and setbacks
• Slab thickness, reinforcement and joint layout
• Finish and color, with a sample photo when the HOA asks
• The driveway location measured from the lot line for any right-of-way work

Building on Sandy Lots Near the River and Creeks

St. Johns sits on the same sandy soils found across Northeast Florida. Sand drains and compacts well when it is handled right, and it shifts when it is not.

Compacting sand and builder fill

New subdivisions often have fill brought in during site work, and the top few inches around a house can be loose from landscaping and irrigation trenching. We cut to firm material, compact in lifts with a plate compactor, and wet the sand before the pour so it does not pull water out of the fresh concrete.

Water table and drainage near Julington Creek

Lots closer to the river, Julington Creek and the wetland preserves can sit near a high seasonal water table. We check where the water goes after a storm, keep slabs above the surrounding grade, and avoid pouring patios into low spots that hold water in late summer.

Irrigation lines and sprinkler heads

Nearly every yard here has an irrigation system. We flag heads and lines before digging, reroute where a new slab covers them, and set sleeves under driveways and walks so a future repair does not mean cutting concrete.

What Concrete Work Costs in St. Johns

Pricing is per square foot, installed, and depends on access, demolition, thickness, reinforcement and finish. These are our typical ranges:

Why small add-ons cost more per foot

A 6-by-30-foot driveway strip carries the same truck, crew and setup as a much larger slab, so it often lands at the higher end of the range. Grouping a widening, a patio extension and a side walk into one pour usually brings the per-foot number down.

What moves a quote up or down

Removing old concrete, hauling off spoil, doweling into existing slabs, matching an exposed aggregate or stamped finish and pump access to a backyard all add cost. A wide-open front yard with a straight run from the street keeps it lower.

Decorative finishes on newer homes

Many St. Johns owners want the backyard to look finished, not just bigger. Exposed aggregate and stamped patterns cost more per foot than a broom finish, so a common compromise is a broom-finished slab with a decorative border, or a stamped patio paired with a plain driveway widening. We price each option separately so you can mix and match.

Pouring Around CR-210 Traffic and Florida Weather

Getting a concrete truck into a St. Johns neighborhood on time is its own part of the job, and the weather sets the rest of the schedule.

Scheduling trucks along CR-210

CR-210 carries heavy traffic, and construction around the First Coast Expressway extension toward I-95 adds to it. We schedule ready-mix early in the morning, before the worst of the commute, and confirm gate codes and parking with you so a loaded truck is not waiting at the entrance.

Hot-weather pours and afternoon storms

In July the average high in the Jacksonville area runs about 91°F, and a thunderstorm can roll through most afternoons. We start pours at first light, use an evaporation retarder when the sun is strong, and keep the slab damp during the first days of curing. If radar shows a storm on top of the pour window, we move the date rather than gamble with a rained-on finish.

After the crew leaves

The first week decides a lot about how a slab ages. Keep sprinklers from pooling on the new concrete, keep cars off for at least seven days, and keep landscapers from parking mowers or trailers on the edge. We pull forms and backfill along the sides once the concrete has set, so the edges are supported by soil instead of hanging in the air.

Frequently Asked Questions

Do I need a county permit to widen my driveway in St. Johns?

If the widening reaches into the county right-of-way between the sidewalk and street, St. Johns County requires a driveway/culvert permit unless the work is covered by an active building permit. Work that stays entirely on your lot usually needs only HOA approval, but we confirm the details for your address before we quote.

Can a new strip of concrete match my existing driveway?

It can match closely in finish and joint layout, but new concrete is always a little lighter than a slab that has weathered for years. The color evens out over time. We dowel the new section into the old one so the two stay level.

How thick should a driveway be for a boat or RV?

Standard car traffic does well on 4 inches over compacted sand. For a boat trailer, RV or heavy work truck we recommend 5 to 6 inches with rebar at about 18 inches on center, plus thickened edges where tires roll on and off.

When can I drive on my new driveway?

You can walk on it after a day or two. Wait at least seven days before parking cars on it, longer for heavier vehicles. Concrete keeps gaining strength for about 28 days, and summer heat is one more reason we keep it moist early.
