Concrete Repair in Corona, CA

Concrete repair is often the smarter first step. With a median home build year of 1991 in Corona, according to American Community Survey figures summarized by Point2Homes, many driveways, walks and patios have had 30 years or more to crack, settle and wear. Not all of that concrete needs to come out. A lot of it can be repaired for a fraction of the cost of replacement, as long as the cause of the damage is addressed too.

What we repair

• Cracks: cleaned out and filled with flexible or rigid filler depending on whether they move.
• Sunken panels: driveway, walkway and patio sections lifted back to level by mudjacking or foam leveling.
• Trip hazards: raised edges on walks and patios leveled, ground down or replaced.
• Worn and spalled surfaces: sound slabs resurfaced with a bonded overlay.
• Broken sections: individual panels saw-cut out and replaced without redoing the whole driveway.
• Steps and edges: chipped step noses and broken slab edges rebuilt.

Repair, level, resurface or replace

The right fix depends on what is wrong. HomeGuide's resurfacing guide recommends repair or resurfacing for minor flaking and cracks under about 1/4 inch wide, and replacement for large cracks, crumbling, spalling, structural problems, or any repair that would need an overlay more than 2 inches thick. A panel that sank in one piece but is otherwise sound is a good candidate for leveling. A panel broken into several pieces usually is not.

Price matters in that choice too. Per HomeGuide's leveling guide, mudjacking runs about $4 to $9 a square foot and polyurethane foam about $8 to $25, while tearing out and replacing a slab runs about $6 to $15. Its resurfacing guide puts a bonded overlay at roughly $3 to $7 a square foot.

Fix the cause, not just the crack

Most concrete damage in Corona comes from a few sources: water getting under a slab during winter storms, tree roots, poor original base compaction, heavy vehicles on thin concrete, and age. Freeze-thaw damage is rare here, with average winter lows around 40 degrees. If a downspout empties next to a sunken panel or a parkway tree is lifting the walk, leveling the slab without dealing with that will not last. HomeGuide notes that leveling without fixing the drainage problem that caused settling is likely to lead to resettling. We point out the cause and include the fix in the quote when it is part of our work.

Sidewalks and the public right-of-way

The City of Corona's Street Maintenance division maintains about 750 miles of sidewalks, and residents can report street and sidewalk issues through the city's online service request system. A sidewalk panel in front of your house may be the city's concern, or it may be yours, depending on the situation. Before we repair concrete in the right-of-way, we check with the city for your address.

What to expect from each fix

Lifted slabs generally stay put for 5 to 10 years or longer in HomeGuide's estimate, and foam tends to outlast mudjacking. A resurfaced slab usually goes 8 to 15 years before it needs attention again. Filled cracks last longest when sprinklers and downspouts are kept off the slab edges.
