Concrete has a reputation for durability, but it isn't crack-proof. The good news is that a crack rarely means you need to replace the whole surface. Repairs and concrete resurfacing are often the faster, more affordable path forward.

But even properly installed concrete can crack over time due to outside conditions. Concrete handles compression well, but it's weak under tension or bending, so stress tends to show up as cracks.
In Florida, heat expansion, heavy rain, and humidity all put extra strain on a slab over the years. During hurricane season, saturated soil beneath a slab can shift or erode, and when the ground dries back out it contracts, that swelling and shrinking puts real stress on the concrete above it.
How a crack gets repaired depends entirely on what kind it is. Assessing the type and severity comes first. Here's a rundown of the most common types and how each one is typically handled:
These thin cracks form naturally as concrete cures and shrinks. They're not usually a structural concern, but they still need to be sealed to keep water from working its way in.
Repair tip: A crack filler or adhesive is usually enough to seal it up.
Wider and more irregular than hairline cracks, these typically form when concrete dries too fast or the water in the mix wasn't quite right.
Repair tip: Crack filler or adhesive can stop the spread. For bigger cracks, resurfacing may be the better call.
These show up when the ground under the slab wasn't compacted well, or when weight was placed on the concrete before it fully cured. The result is often an uneven surface.
Repair tip: Smaller settlement cracks can be ground down and sealed. Larger ones may call for resurfacing or, in some cases, replacement.
The most serious type, wide, deep, and usually tied to poor reinforcement or a shifting base. In Florida, storm-driven soil movement can be a contributing factor.
Repair tip: When structural cracks are severe, replacing the slab is often the more effective long-term fix.
Before any repair begins, it's worth figuring out what actually caused the crack, otherwise, you're just addressing the symptom. Common culprits include moisture and heat, poor installation, or other factors like tree roots pushing up from below or storm-related soil movement. If inadequate reinforcement is to blame, a surface-level fix won't be enough on its own. A professional contractor can pinpoint the cause and recommend the right approach.

When your slab is still structurally sound, resurfacing is the more sustainable option compared to full replacement. It works especially well for hairline and shrinkage cracks, and sometimes settlement cracks too, depending on severity. There's no demolition labor, no cost of tearing out old material, and no old concrete headed to a landfill. You keep the existing slab and simply give it a fresh, updated look.
What you'll pay depends largely on how big and how severe the cracks are. Small hairline cracks are often an easy, inexpensive fix with basic crack filler. Anything more extensive calls for a professional look. SUNDEK of Tampa can assess the damage and point you toward the repair method that makes the most sense.
Smaller cracks can sometimes be a reasonable DIY project, but the results only last if you're using the right products and following the correct process. Done poorly, a DIY repair can actually make things worse or invite the crack right back. If you want a finish that holds up, it's worth bringing in an experienced contractor.
