Concrete & Foundation Work | Tampa Bay

A slab is only as good as the ground it sits on. On Florida sites that ground moves: sandy soils shift, clay expands and contracts with moisture, and the seasonal water table rises and falls through the year. Concrete placed on unprepared or inconsistently compacted subgrade will crack, and no amount of reinforcement in the mix will prevent it.

We treat subgrade preparation and compaction as the main event rather than a preliminary, because that is what determines whether the finished surface stays flat.

Subgrade preparation

The subgrade has to be stripped of organics, graded to a consistent level, and compacted in lifts to a uniform density. Soft spots have to be removed and replaced rather than bridged over, because a soft spot under a slab becomes a crack in the slab. On fill lots, this is where most of the quality of the finished work is decided, and none of it is visible afterwards.

Reinforcement and control joints

Reinforcement resists tension; it does not stop cracking, it holds cracks tight and keeps the slab performing as one piece. Control joints are cut to give the concrete a defined place to crack, because concrete shrinks as it cures and will crack somewhere regardless. Joint spacing, depth and timing all matter, and cutting too late means the crack has already chosen its own path.

Driveways, patios and flatwork

Exterior flatwork takes more abuse here than structural slabs do: intense sun, heavy rain, and in many soils a seasonal water table directly beneath it. That means adequate thickness, proper edge support, and a finish that provides grip when wet. Drainage away from the structure is designed in, not left to the fall of the surrounding ground.

When to call

Pouring a slab for a new build or addition
A driveway, patio or walkway is cracked or settled
You need a foundation for a shed, garage or outbuilding
An existing slab has cracked and needs assessment
You need footings for a screen enclosure or carport
Water is pooling against the house rather than draining away

How the work is handled

Site and soil assessment before any excavation
Stripping, grading and compaction of the subgrade
Formwork, reinforcement and any embedded services set
Pour, finish and curing under controlled conditions
Control joints cut and drainage established

What affects the cost

We do not quote a number before seeing the property, because the same job on two similar houses can need different work. These are the factors that move the scope:

Area and thickness of the pour
Depth of excavation and whether fill has to be imported
Reinforcement specification and slab thickness
Site access for the concrete truck and pump
Finish type, including any decorative treatment
Removal and disposal of existing concrete

Frequently asked questions

Why does concrete crack?

Concrete shrinks as it cures, and it will crack somewhere. Control joints are cut so it cracks where you planned rather than where it wants to. Cracks beyond the control joints usually indicate a subgrade problem, which is why preparation matters more than mix design.

How long before I can drive on a new driveway?

Concrete reaches most of its strength within the first week but continues curing for weeks afterwards. Foot traffic comes well before vehicle traffic. We give you a specific timeline for your pour based on thickness and conditions rather than a generic figure.

Can you pour over an existing slab?

Sometimes, if the existing slab is structurally sound and the added height is acceptable. More often the existing material has to come out, because pouring over a failed slab simply transfers the failure upward.

Does a slab need a vapour barrier?

For conditioned interior slabs, yes. A barrier under the slab limits moisture moving up through the concrete, which matters for flooring and for interior humidity in this climate.
