Concrete Crack Repair

Cracked concrete is a common issue that can impact your property’s safety and appearance, signaling underlying problems and causing additional damage. 

Managing cracked and sunken concrete can be stressful for homeowners. At Bay Area Underpinning, we offer an effective concrete lifting solution that directly tackles these concerns. 

Our exclusive SettleStop™ PolyRenewal™ polyurethane injections raise sunken concrete slabs and can help seal cracks once the concrete is stabilized. With nearly 20 years of trust from homeowners in the Bay Area, we invite you to experience our innovative and excellent services for yourself. 

As industry-leading concrete repair experts, our primary goal is to provide customized guidance and solutions for your home. This page details how our specialized services enhance your property’s safety.

What is Concrete Crack Repair?

Concrete crack repair is a comprehensive process that addresses concrete surface damage caused by unstable, expansive soil, oversaturated soil, and dry soil. 

Mere patching of cracks with caulk or other materials is not enough, as it only addresses the cosmetic appearance while concealing underlying issues.

Bay Area Underpinning’s concrete repair goes beyond surface fixes. We employ the PolyRenewal™ concrete lifting process to gently elevate sunken sections.

Our proprietary concrete lifting system is a crucial element of our holistic home solutions, ensuring the aesthetics and safety of your concrete structures. PolyRenewal™ focuses on stabilizing the concrete, often reducing visible cracks and sealing them after the slab solidifies.

Signs Your Home Needs Concrete Crack Repair

Concrete cracks can appear on various surfaces, including:

If you see damage to your property’s concrete surfaces, it may be time to consider a repair solution. Here are some common signs:

  • Visible and expanding cracks in concrete surfaces
  • Cracks wider than ¼”
  • Uneven or sinking concrete slabs
  • Tripping hazards
  • Concrete sinking away from the house
  • Cracked walls or damaged siding above sunken concrete
  • Crumbling edges
  • Pitting, flaking, and staining on the concrete
  • Water pooling on the concrete after rain
  • Weeds growing between concrete sections

By recognizing concrete cracks and other damage early, you can allow for less invasive repairs, safeguarding your investment and preventing further costly damage.

Is Concrete Crack Repair Necessary?

Concrete crack repair is essential. Be cautious of “quick fixes” and conventional repairs—including mudjacking or repouring—that don’t address the root cause, as they lead to more significant issues. 

Timely action prevents further deterioration, ensuring your slabs last longer and saving you money in the long run. The sooner you address concrete damage, the less invasive the repair. 

Early action also maximizes the effectiveness of solutions like PolyRenewal™, a vital component of our comprehensive home solution.

What Are the Benefits of Concrete Crack Repair

Concrete crack repair offers numerous advantages:

Improved Safety

Lifting uneven, sunken areas of concrete eliminates tripping hazards. Sealing cracks prevents further fractures that could harm loved ones or vehicles, enhancing property safety.

Avoiding Additional Damage

Injecting expanding foam under compromised concrete slabs stabilizes the ground to prevent continued sinking and settlement, protecting your investment.Enhanced Appearance and Value

Enhanced Appearance and Value

Cracked, uneven concrete diminishes your property’s value and looks unsightly. Our solutions can make cracked surfaces look new again, restoring your concrete to its original, smooth appearance.

Extend Concrete Life

Untreated minor cracks can lead to major repairs. Concrete lifting and stabilization treatments strengthen surfaces and extend their lifespans, avoiding the need for complete slab replacement. 

We encourage homeowners to utilize our proprietary PolyRenewal™ system to maximize these benefits. Our exclusive products, designed with expertise, outperform generic solutions by providing superior performance and durability.

How Our Concrete Crack Repairs Work

To comprehensively address concrete cracks, Bay Area Underpinning’s certified team follows these essential steps when installing PolyRenewal™:

  • Inspect the concrete for damage, determine the cause, and outline the best repair solution.
  • Drill small, penny-sized holes into the concrete.
  • Affix injection ports in each hole.
  • Mix the two-part, closed-cell polyurethane foam.
  • Inject the foam under the concrete slabs through the ports.
  • Allow the foam to expand, fill voids, and cure (approximately 15 minutes).
  • Ensure proper slab lift and stabilization.
  • Remove the injection ports.
  • Fill and smooth out the drilled holes.
  • Seal cracks and joints to prevent future damage.
  • Schedule annual maintenance for continued concrete slab protection.

With the right tools, training, and products, Bay Area Underpinning’s concrete repair process is efficient, minimally invasive, and delivers long-lasting results.
