Concrete Crack Repair

Concrete repair in progress.

Concrete cracks are a safety risk, and it’s only a matter of time before they cause a nasty fall. If that’s something you want to avoid, it’s best to invest in concrete crack repair.

With Bay Area Underpinning, you’ll receive an industry-leading repair method. Since 2005, we’ve been helping homeowners in Northern California lift and level their concrete structures. Read on to see how we do it and why it’s a good idea.

What is Concrete Crack Repair?

Concrete crack repair is the process of fixing surface cracks on concrete (specifically, with concrete lifting). With these repairs, concrete surfaces become smoother and safer.

Think of any concrete you have on your property. You might have a concrete pool deck or a concrete porch. If these have cracks, what could happen while you try to relax? Not a fun thought.

Our concrete crack repair method uses a modern material called polyurethane foam. As the foam goes under the concrete, it expands, closes cracks, and lifts the structure. In just 15 minutes, polyurethane cures to its final strength and supports the newly lifted concrete.

Signs You Need Concrete Crack Repair

Concrete cracks can show up on any concrete surface. Good news, though—they’re easy to spot, so keep an eye out for these issues:

Cracked concrete at a home.
  • Cracks of any kind, especially those more than a ¼” wide.
  • Weeds or roots growing through the concrete.
  • Uneven or sinking sections of concrete. 
  • Edges of the concrete breaking off. 
  • Surface damage such as pitting, flaking, or staining.

While it can be tempting to ignore concrete cracks, the problem never fixes itself. If you notice any of these issues, no matter how small, contact Bay Area Underpinning for a free inspection. It never hurts to play it safe.

Is Concrete Crack Repair Necessary?

Repairing concrete isn’t fun, and that’s a fact. Finding the right solution can be a tedious process, and you might feel it’s not even worth the effort. Still, concrete crack repair is necessary.

Repairing concrete cracks enhances your property’s look, and more importantly, it increases your home’s overall safety. Consider what might happen on a cracking concrete surface. Kids running around on a cracking pool deck could end in a costly accident (and that’s just one example).

Concrete crack repair is one of the best investments you can make in your home. To ensure the job is done right, work with a professional team like Bay Area Underpinning.

FAQs

All cracks can pose a threat to your concrete. While hairline cracks may not be a major concern, cracks wider than ¼” should be repaired promptly. Avoid DIY fixes and opt for professional solutions from Bay Area Underpinning. Our PolyRenewal™ system lifts and stabilizes concrete and can help close cracks. Contact us for a free inspection and estimate.

We do not use conventional fillers for concrete cracks. Our approach involves injecting high-density polyurethane foam under concrete to lift and stabilize it. While we do not “repair” concrete cracks, we can often close them when lifting concrete slabs. Contact us to learn more and to schedule a free inspection and estimate.

Typically, the entire concrete lifting process can be completed within a day, depending on the severity of the damage and the scope of the job. The PolyRenewal™ injected foam cures in 15 minutes, allowing you to use the surface shortly after repair. Bay Area Underpinning experts will provide an accurate installation timeline during a free inspection appointment.

Disclaimer: “Concrete leveling” means the process by which cracked, uneven concrete is stabilized, and in many cases lifted, by means of PolyRenewal™ polyurethane foam. Bay Area Underpinning does not guarantee that PolyRenewal™ can make your concrete perfectly level.
