Concrete Repair & Restoration

Don't Replace It, Repair It

Cracked concrete doesn't always mean you need to tear everything out and start over. Many concrete problems can be effectively repaired for a fraction of the cost of replacement. The key is identifying what caused the damage and addressing it properly so the repair lasts.

At KeenCraft Corona Concrete, we've been repairing concrete in Corona since 2024. We assess each situation honestly. Sometimes repair makes sense, sometimes replacement is the better choice. We'll give you the straight answer about what will work and what won't, along with a realistic expectation of how long the repair will last.

Concrete Problems We Can Fix

Surface Cracks

Hairline cracks are common in concrete and usually aren't structural problems. We can fill and seal them to prevent water penetration and stop them from widening. For wider cracks (1/4 inch or more), we assess whether they indicate settling, foundation issues, or just normal concrete movement.

Spalling and Surface Damage

Spalling is when the concrete surface flakes, chips, or pops off. This often happens from freeze-thaw cycles (less common in Corona), salt damage, or poor initial finishing. We remove damaged material and resurface with specialized concrete products that bond to the existing surface.

Settled or Sunken Sections

When concrete settles or sinks, it creates trip hazards and drainage problems. We can often level these areas using mudjacking or polyurethane foam injection. These techniques lift the settled concrete back to the proper grade without the mess and cost of replacement.

Deteriorated Joints

Control joints and expansion joints deteriorate over time. Water and debris get into the joints and cause damage. We clean out old material and install new joint sealant that keeps water out and allows for proper concrete movement.

Our Repair Techniques

Different problems require different solutions. Here are some methods we use:

• •Epoxy injection: For structural cracks, we inject epoxy resin under pressure to fill the crack completely and restore strength. This creates a bond stronger than the surrounding concrete.
• •Surface patching: We use specialized repair mortars designed to bond to existing concrete. These products handle thermal expansion similar to original concrete and provide a durable repair.
• •Slab leveling: Mudjacking pumps a cement-based slurry under settled slabs, lifting them back to grade. It's proven technology that's been used successfully for decades.
• •Concrete resurfacing: For worn or damaged surfaces that are structurally sound, we can apply a new surface layer. This works great for patios and driveways where the base is fine but the top surface is deteriorated.

Should You Repair or Replace?

Here's how we help you decide:

Repair makes sense when the underlying structure is sound, the damage is localized, and the cause has been addressed. For example, a cracked driveway section caused by a tree root can be repaired after removing the root. Surface spalling on an otherwise good patio can be patched and resurfaced.

Replacement is better when there's widespread damage, severe settling, or ongoing structural problems that can't be corrected. If your concrete has multiple large cracks, significant unevenness, or was poorly installed to begin with, replacement often costs less in the long run than trying to patch everything.

We'll assess your situation and give you an honest recommendation. Sometimes a targeted repair buys you several more years, which might be all you need. Other times, investing in replacement makes more financial sense. We explain the pros and cons of each approach so you can make an informed decision.
