Concrete Leveling & Mudjacking in Jacksonville, FL by Jacksonville Professional Concrete
Jacksonville Professional Concrete lifts sunken slabs back to grade for homeowners and property managers across Duval County. Our concrete leveling and mudjacking in Jacksonville, FL fixes dropped driveway panels, tilted sidewalk sections and patios that now slope toward the house, usually in a single visit and for far less than tearing out good concrete.
Most settlement here starts with water and sand. Jacksonville sits on sandy marine-terrace soil, and when a downspout or a summer thunderstorm keeps sending water under a slab, it carries fine sand away and leaves a hollow. The concrete above is often still solid and worth saving. It just lost the support underneath it.
We find the void, choose the right lifting material, raise the slab in small increments and seal everything back up. We also point out the drainage problem that caused the drop so it does not happen again. If a slab is too broken to lift, we tell you that plainly and price a replacement instead.

Our Concrete Leveling Services in Jacksonville
Mudjacking (slabjacking)
Mudjacking pumps a cement-based slurry through holes about 1 to 2 inches across. The grout fills the hollow under the slab, then builds enough pressure to raise it. It is a heavy, dense fill that works well on thick driveway panels and garage approaches where the void is large. We lift in stages, checking with a level as we go, and patch every hole with a matching cement mix when the slab reaches its target height.
Sidewalk and walkway trip hazards
Uneven sidewalk joints are a real hazard, especially on older walks in Riverside and Avondale where live oak roots and decades of runoff have pushed panels out of line. We lift the low side to match the high side, grind a minor lip if needed and reseal the joint. If a root is the cause, we explain your options before lifting, since raising a slab over an active root only buys time.
Driveway and garage apron lifting
A driveway panel that drops at the garage door creates a lip that catches tires and lets rain run back toward the house. We raise that panel flush with the garage slab and restore fall toward the street. On homes in Mandarin and the Southside where the original builder left loose fill along the foundation, this is one of the most common repairs we make. Joints get resealed afterward so runoff cannot wash out the sand again.
Polyurethane foam lifting
Foam lifting uses smaller holes, roughly 5/8 inch, and a two-part polyurethane that expands beneath the slab. It weighs far less than grout, which matters on sandy ground that is already struggling to hold a load. Foam is also closed-cell, so it does not soak up water during a wet September. The slab is usually ready for foot traffic within minutes and vehicles shortly after, which makes it a good fit for busy driveways and walkways.
Patio and pool deck leveling
Screened lanais and pool decks see constant water from rain, splash-out and sprinkler heads. Once the sand underneath erodes, a section tips toward the house or the pool. We lift it back to a proper slope, typically about 1/8 inch per foot away from the structure, so water drains off the surface. Foam is our usual choice around pools because the holes are small and the fill stays stable when wet.
Commercial slab and walkway lifting
Stores, offices and apartment communities call us when a sunken entrance slab or sidewalk panel becomes a liability. We can lift during off-hours, keep part of the walk open and have the area back in service quickly. For walks that must meet ADA accessibility rules, we lift to eliminate vertical changes greater than 1/4 inch and check the cross slope so the finished surface stays within accessible limits.
How Our Leveling Process Works
Inspect and measure
We walk the slab, measure how far each section has dropped and look for the water source behind the problem. Gutters, downspouts, irrigation and low spots in the yard all show up here. We also check the slab for cracks that would make lifting risky, then recommend grout, foam or replacement with a written price.
Drill access holes
We mark a hole pattern that spreads the lifting force across the panel instead of loading one spot. Holes are placed away from joints and edges where possible. Nearby surfaces get protected, and on decorative or stamped concrete we keep holes in grout lines or less visible areas.
Lift in controlled stages
Material goes in a little at a time while we watch string lines and levels on every side of the slab. Slow lifting reduces the chance of new cracks and lets us stop exactly at the target height. We fill remaining voids so the slab is supported across its full area, not just at the injection points.
Patch, seal and fix the water
Every hole is patched, and the joints along the lifted slab are sealed with a flexible sealant to keep rain from reaching the sand below. We point out drainage fixes, like a downspout extension or regraded soil, that help keep the slab where we put it.
Frequently Asked Questions
How much does concrete leveling cost in Jacksonville?
Leveling is priced by the job, based on how many panels need lifting, the size of the void and whether we use grout or foam. In most cases it costs a fraction of replacement. For comparison, a new driveway runs about $6–$10 per square foot installed and a new sidewalk about $8–$14, plus tear-out and haul-off. We give you both numbers when replacement is on the table.
Why does concrete sink in Jacksonville?
Our soil is mostly fine sand with a seasonal high water table that can rise to within a few feet of the surface. Water moving under a slab carries sand with it, especially near downspouts, pool decks and irrigation lines. Poor compaction during original construction adds to it. The concrete then spans a hollow until it cracks or drops.
Is mudjacking or foam better for my slab?
Foam is lighter, uses smaller holes, resists water and cures fast, so it suits most residential driveways, walks and pool decks on our sandy ground. Mudjacking makes sense for very large voids under thick slabs where a dense cement fill is the better support. We recommend one after measuring the slab and probing the void, not before.
Will hurricane season or summer rain undo the repair?
Heavy rain from June through November is exactly what causes most settlement, so we design the repair with it in mind. Filling the full void and sealing the joints keeps water from reaching the sand. If runoff from a roof or yard still points at the slab, redirecting it is the step that protects your repair through the next big storm.
How soon can I use the concrete after leveling?
With foam, you can usually walk on the slab right away and drive on it within about 15 to 30 minutes. Mudjacked slabs need longer for the grout patches and fill to set, so we typically ask you to keep vehicles off until the next day. We will give you a specific time before we pack up.
Do I need a permit to level a city sidewalk in front of my house?
Lifting a public sidewalk or driveway apron sits in the City of Jacksonville right-of-way, which generally requires a Right-of-Way permit through JaxEPICS. Work on your own driveway, patio or walkway does not. If your property is in Jacksonville Beach, Atlantic Beach or Neptune Beach, those cities handle their own permits.
