Concrete Step Repair

Completely repaired concrete steps.

Tired of dodging cracks and dips in your concrete steps? You need concrete step repair, and Bay Area Underpinning can help.

Since 2005, we’ve been helping homeowners in Northern California repair their concrete steps with our industry-leading concrete leveling method. Read on to see how we do it and why it’s a good idea.

What is Concrete Step Repair?

Concrete step repair involves lifting, stabilizing, and restoring damaged, sinking, or cracked exterior concrete steps.

Conventional repairs, such as mudjacking, or concrete replacement, are not lasting solutions. They also fail to address the root of the problem.

Advanced methods like concrete lifting with polyurethane foam injections are superior alternatives. Bay Area Underpinning installs the exclusive PolyRenewal™ system, guaranteeing the longevity and safety of your steps.

Signs You Need Concrete Step Repair

Addressing concrete step damage early to prevent further issues is crucial. Signs that your stairs need repair include:

Cracking steps at the front of a home.
  • Sinking porch
  • Hollow sounds under the steps
  • Pooling water or drainage issues
  • Deteriorating edges or corners
  • Pits, flakes, or stains on the concrete

Identifying these early signs of concrete damage can save you time and money. Contact a concrete repair professional like Bay Area Underpinning when you notice these symptoms.

Is Concrete Step Repair Necessary?

Absolutely. Neglecting to repair damaged concrete steps compromises safety, limits your repair options, and can escalate future repair costs. Quick action prevents ongoing damage and ensures safety and longevity.

Avoid re-pouring, mudjacking, or quick-fix solutions offered by big-box stores. These repair methods are only temporary and do not address the underlying issue.

Timely concrete step repair is an essential part of Bay Area Underpinning’s comprehensive whole-home solution, preserving your property’s integrity and value.

Our experts will assess the full scope of damage and restore your steps promptly.

How We Install Concrete Step Repair

Bay Area Underpinning’s experts follow these essential steps during the PolyRenewal™ installation process:

  • Evaluate the steps’ damage, pinpoint the cause, and plan the correct repairs.
  • Drill small holes into the sunken areas of your concrete steps.
  • Insert injection ports into the drilled holes.
  • Mix a two-part, closed-cell polyurethane foam.
  • Inject high-density polyurethane foam under the concrete.
  • Allow the foam to expand, fill voids, and cure (approximately 15 minutes).
  • Ensure proper concrete lift and stabilization of underlying soil.
  • Remove the injection ports and fill the holes.
  • Seal cracks and joints with a protective sealant.
  • Schedule regular maintenance inspections to monitor your concrete steps.

Exterior concrete steps can sustain damage, including cracking and sinking, for various reasons. Most issues are caused by the property’s soil, such as expansive soil complications, soil settling and erosion, oversaturation, and shifting due to growing tree roots. Bay Area Underpinning determines the cause of the damage and the best repair solution during a free inspection.

Step repair costs vary based on the extent of damage and necessary repairs. For instance, the cost of concrete lifting with polyurethane injections differs from pier installation for foundation-based problems. Contact Bay Area Underpinning for an accurate cost breakdown and financing options during a free inspection with one of our experts.

The estimated installation timeline for PolyRenewal™ depends on the area requiring repair and the amount of damage. However, in most cases, concrete step repair can be completed within a day. Once the foam is injected beneath the concrete, it takes approximately 15 minutes to cure, compared to mudjacking or repouring, which may require several days to fully restore functionality. Contact us to schedule a free inspection and estimate.

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.
