Concrete Slabs and Pads in Palm Bay, FL

Slabs and pads we pour across Brevard County

Shed and workshop slabs are the classic backyard pad. The pad is usually poured a few inches wider than the building on every side. That keeps the wall line off the edge and gives the anchors solid concrete to bite. Detached garage and carport slabs are the same idea at a bigger size. Driveway extension and parking pads get poured to vehicle thickness, and our concrete driveway installation page covers full driveway pours. Extensions tied into an existing drive are on our driveway extensions page.

Equipment pads are smaller but fussier. An air conditioner pad has to sit above the surrounding grade so runoff does not pool around the unit. A hot tub pad has to be flat and level, because a filled spa is heavy and unforgiving. Generator pads follow the same rule. Lanai and patio slab extensions tie into what is already there. Our concrete patio pours page has more on that side of the work. Grill pads and AC pads often go in on the same trip.

How thick should a concrete slab be?

Four inches is the working number for most residential pads. A shed slab, a hot tub pad, or an air conditioner pad sits fine on four inches. What matters more is the base under it. Once wheels are involved we go thicker. Parking pads, RV pads, and boat pads get five to six inches. A loaded rig puts thousands of pounds on four small contact patches. A detached garage floor gets the same treatment when a truck lives in it.

Steel is the other half of the answer. Most pads get welded wire mesh, and heavier pads get a rebar grid tied at the laps. Either one rides on chairs so the steel sits in the middle of the slab. Steel laying on the ground does nothing. Reinforcement does not stop concrete from cracking. It holds the two sides of a crack together so the pad stays one piece and stays flat.

How do we build a slab that lasts in sandy soil?

Brevard sits on sandy flatwoods soil. It drains fast, but loose sand settles under a load. A pad on soft ground will drop a corner. We strip the organic layer and cut the pad down to grade. Then we compact the sand in lifts with a plate compactor. Fill goes in the same way, in layers, wet down and packed. On a low spot we add crushed base rock and compact that too. The base is where a slab is won or lost.

Concrete shrinks as it cures, and it will crack somewhere. Saw cut control joints decide where. We cut them about a quarter of the slab depth. Panel spacing runs about two and a half feet for every inch of thickness. On a four inch pad that lands near ten feet. We also build slope into the pour, about a quarter inch per foot. Brevard gets about 51 inches of rain a year, so water needs somewhere to go.

A slab that will be closed in gets poly under it. Ground moisture in this sand will push up through bare concrete and sit on the floor. For a workshop or a garage that holds tools, that sheet of plastic matters. We also thicken the edge where a wall will land. If the pad sits inside a screen enclosure, no machine fits through the door. The mix comes in by wheelbarrow or gets pumped.

Do you need a permit for a concrete slab in Palm Bay?

The answer depends on the size of the pad and what goes on top of it. It also depends on which city you live in. Palm Bay has its own Building Division, and unincorporated Brevard County is handled by Planning and Development. Their rules are not identical, and both can change. We check with the department that covers your address before the pour. Then we build to what the approved plan shows.

A shed slab often rides along with the shed itself. Many shed builders pull their own permit. The plan set calls out the pad size, the thickness, and the anchor pattern. Tell us what the builder is filing and we pour to it. If anchor bolts or straps need to be set wet, we set them while the concrete is still workable. HOA and architectural review is a separate step, and it comes up often around Viera and Suntree.

Most pads are a short job. A typical shed or hot tub pad runs one day of prep and forms, then a pour the next morning. Bigger slabs add a day. After the pour you can walk on it in a day or two. Wait about a week before parking a car or setting a shed on it. Concrete keeps gaining strength for about 28 days, so heavy loads like an RV wait for that mark.

What drives the cost of a concrete slab?

Size and thickness move the number first. A four inch pad and a six inch pad are not close on concrete volume or on steel. Site prep is the next lever. A flat, clear back yard pours cheap. A low corner that needs fill and compaction takes more time and more base rock. Access matters just as much. A truck that can back to the forms beats a pump or a long wheelbarrow run inside a screen enclosure.

Reinforcement and finish fill in the rest. Wire mesh costs less than a tied rebar grid. A broom finish costs less than color or a stamped pattern. Tear out and haul off of an old pad adds a line. A permit adds one too, when the city requires it. We price every pad from the actual site after measuring it. Call us or send the details through the site, and we will set up a free on-site estimate.
