Concrete Repair in Port St. Lucie, FL

Concrete Repair starts with the cause. A crack, a sunken panel or a worn surface each points to something different underneath, and a patch that ignores the cause comes back. In Port St. Lucie, where a large share of homes date from the 1980s and 2000s building waves, a lot of driveways, walkways and pool decks are now old enough to show wear, and many can be repaired for far less than replacement.

What usually causes the damage

• Water under the slab: downspouts, irrigation and heavy summer rain washing fine sand out from beneath an edge
• Weak or thin base: builder-grade slabs on poorly compacted fill settle over the years
• Roots: trees planted close to driveways and walks lift and crack panels
• Heavy loads: trucks, trailers and delivery vehicles on a 4-inch driveway, especially at the edges and the apron over the culvert
• Surface wear: sun, pool chemicals and age wearing down the top layer

The repair options

• Crack sealing: cleaning out and filling cracks so water cannot reach the base. HomeGuide prices crack filling at $0.50 to $3 per linear foot.
• Leveling: raising a dropped panel by pumping material beneath it, either a cement slurry (mudjacking) or expanding foam (polyjacking)
• Resurfacing: a thin overlay over concrete that is structurally fine but worn, stained or flaking, in plain, textured or stamped finishes
• Panel replacement: cutting out only the broken sections and pouring new concrete tied into the sound slab around them

Repair or replace?

HomeGuide's resurfacing guide gives a practical dividing line. Light flaking and cracks under 1/4 inch wide are usually candidates for repair or an overlay. Wide cracks, crumbling, spalling, structural trouble, or a fix that would need more than 2 inches of new material all point to replacement. A crack wider than 1/4 inch can mean movement below, and that movement will crack an overlay as well. If we find that, you will hear it from us, and for anything touching the house foundation we send you to a structural engineer rather than guess.

Driveway aprons and the culvert

The driveway apron, where it crosses City right of way to the street, is one of the most common repair spots in Port St. Lucie. A crushed or failing culvert pipe under it lets the ground drop and the concrete break. Fixing the concrete without fixing the pipe does not last. Repairs to an existing driveway are on the City of Port St. Lucie Public Works Department's Residential Driveway Modification Permit, and the form notes the culvert may need to be replaced or brought up to code, so we check the pipe and the permit before quoting a fix there.

Leveling sunken concrete

Lifting works when a panel has dropped but has not broken apart. Mudjacking is the cheaper route. Polyjacking needs smaller holes and puts less weight under the slab, and HomeGuide says it often lasts the longest; it gives mudjacking about 5 to 7 years with good drainage. Neither one fixes the reason the panel sank, so we also look at downspouts, irrigation and grading to stop water from washing the soil out again.

Signs you should call

• Trip edges on walkways or at the garage door
• A gap opening between the driveway and the garage slab, or between the pool deck and coping
• Panels tilting toward the house
• Cracks that keep getting wider
• Flaking, pitted or stained surfaces that will not clean up

Catching these early usually means a smaller, cheaper fix.
