Sinking Concrete Steps

As a homeowner, the stability of your steps is key for safe access to your home. Sinking concrete steps not only diminishes your home’s appearance but also creates significant safety concerns, including trip hazards. 

Foundation Recovery Systems is your trusted partner in resolving these issues, offering cutting-edge solutions that prioritize both safety and the visual appeal of your home. Our advanced concrete lifting techniques are designed to restore your home’s integrity and charm. 

This page provides valuable insights into why concrete steps sink and how Foundation Recovery Systems’ specialized solutions address these problems effectively. 

What Are Sinking Concrete Steps? 

Sinking concrete steps are characterized by visible sinking or shifts in concrete stairs, resulting in uneven surfaces. These issues not only compromise safety but also hint at underlying problems, such as shifting soil, which demand immediate professional attention. 

You may also notice similar concrete issues in other parts of your property, including: 

Neglecting sunken steps not only increases the risk of trips but can also lead to complete step failure over time. It’s essential to act promptly and seek professional solutions from Foundation Recovery Systems

What Causes Sinking Concrete Steps? 

Several factors contribute to sinking concrete steps, including: 

  • Soil Settlement: Compacting, shifting, or sinking soil beneath your stairs can lead to settling and cracking of the concrete, especially in expansive soils with high clay content. 
  • Soil Erosion: Water flowing under or against the stairs can erode and wash away the supporting soil, compromising concrete integrity. 
  • Tree Roots: Growing tree roots can disrupt underlying soil and exert upward pressure, potentially lifting and cracking the concrete. 
  • Excessive Moisture: Persistent moisture exposure, such as heavy rain, flooding, and snowmelt, can soften the soil under the stairs and contribute to erosion. 
  • Freeze-Thaw Cycles: Water entering existing cracks that freeze and thaw can expand these cracks over time. 
  • Poor Concrete Workmanship: Low-quality concrete or inadequate curing processes can make concrete more susceptible to cracking and sinking. 

These factors not only impact step stability but also pose a threat to your home’s foundation. It emphasizes the importance of seeking comprehensive solutions from experts like Foundation Recovery Systems. 

Can You Fix Sinking Concrete Steps? 

Yes, repairing sinking steps is possible, but DIY fixes rarely provide long-term solutions. Techniques like mudjacking can be messy and outdated, and often fail to address the root problem. 

A comprehensive approach is key. Addressing both visible damage and underlying issues ensures a lasting solution. Foundation Recovery Systems’ concrete lifting process involves injecting high-density polyurethane foam beneath the concrete to lift and level sunken steps. 

The foam expands rapidly and sets within 15 minutes, ensuring a stable lift. In rare cases, additional specialized foundation repairs, like foundation piers, might be required. 

How to Fix Sinking Concrete Steps 

At Foundation Recovery Systems, our advanced technique, SettleStop™ PolyRenewal™, is used to expertly repair sinking concrete steps. Our detailed process includes: 

  • Assessment: We conduct a comprehensive inspection to assess the extent of the damage, identify root causes, and formulate a repair plan. 
  • Drill Holes: Small holes, approximately the size of a penny, are created in the affected concrete. 
  • Position Ports: Injection ports are carefully placed into these holes in preparation for the next steps. 
  • Mix Foam: We meticulously blend our specialized two-part polyurethane foam. 
  • Inject Foam: High-density foam is injected underneath the affected concrete. 
  • Lift Steps: The foam fills voids between the concrete steps and the soil, gently raising sunken sections as it cures. 
  • Fill Holes: Once the steps are stable, we fill the drilled holes to achieve a smooth, finished appearance. 
  • Fill Cracks: We also address any existing cracks, effectively repairing them to prevent future damage. 
  • Maintain Safety: We offer service and maintenance programs to ensure ongoing stability and longevity. 

Our proprietary concrete lifting foam is precisely engineered for your home’s unique conditions. Unlike DIY solutions, PolyRenewal™ provides a lasting remedy for safely elevating and securing sinking concrete stairs. 

Why Address Sinking Concrete Steps Now 

Promptly addressing sinking concrete steps is crucial for several reasons: 

  • Prevent Further Damage: Delaying repairs allows water to infiltrate and widen existing cracks. Taking swift action helps stop the progression of issues. 
  • Avoid Foundation Problems: Settling soil beneath your steps often signals potential foundation instability, necessitating immediate attention. 
  • Ensure Safety: Sunken and uneven stairs pose a significant risk of trips and injuries. Concrete lifting eliminates tripping hazards and resolves structural instabilities, enhancing safety. 
  • Preserve Property Value: Sinking, cracked stairs detract from your home’s visual and curb appeal. Reliable repairs maintain and enhance both the aesthetic and structural value of your property. 
  • Long-Term Solution: Our concrete lifting repairs come with comprehensive warranties, providing peace of mind. Taking action now can save you from more costly repairs down the road.
