This page sheds light on common concrete problems like sinking porches and highlights the importance of professional repair for long-lasting protection. 

What Is a Sinking Porch? 

A sinking porch is a frequent issue characterized by the noticeable settling or descent of the porch from its original position. 

This occurrence typically arises due to underlying soil or foundation stability problems, resulting in cracks, tilting, and misalignment in the porch’s structure. Besides being aesthetically displeasing, it also presents safety hazards, including the risk of tripping. 

A sinking porch often coexists with other concrete issues, including: 

These problems demand immediate attention and professional intervention to prevent further deterioration and preserve the overall structural integrity of your home. If you observe any of these issues, don’t hesitate to reach out to Ohio Basement Systems for expert assistance. 

Why Your Porch is Sinking 

Various factors lead to concrete failure, including: 

  • Soil Settlement: Over time, soil compaction, shrinkage, and settlement happen beneath the porch, often at uneven rates. This uneven settling is a primary cause of many sinking porches. 
  • Soil Erosion: Water flowing under the porch can erode the soil, causing specific areas to sink. Downspouts directing rainwater too close to the porch can exacerbate erosion. 
  • Excessive Rain or Flooding: Flooding can wash away soil under a portion of the porch, resulting in sinking. 
  • Freeze-Thaw Cycles: Runoff from snowmelt and repeated freezing and thawing of the ground can contribute to sinking. 
  • Tree Roots: Trees absorbing moisture from the soil near the porch’s foundation can cause uneven settling. Tree roots can also shift the soil and exert pressure on the porch, compromising its support. 
  • Poor Concrete Pouring/Curing: Inadequate concrete pouring or curing during construction can create vulnerabilities. Over time, this can cause the concrete to crack, shift, or sink due to insufficient support. 

Over time, continued settling can lead to extensive structural damage that impacts the porch and the home’s entire foundation. The longer you wait, the worse (and more costly) the repairs. Swift action is critical to protect your investment and avoid major foundation repairs in the future. 

Can You Fix a Sinking Porch? 

Yes, repairing a sinking porch is possible. 

However, effectively addressing this concern requires a comprehensive approach to home restoration. It is imperative to conduct a thorough inspection and implement a holistic solution that tackles the underlying causes systematically. 

While quick fixes may provide temporary relief, they do not ensure long-term stability and safety. We strongly advise against DIY repairs or investing in methods like mudjacking

At Ohio Basement Systems, we employ a proven proprietary solution that solves the root causes of sinking porches, such as eroding soil, tree root damage, or other issues. Our PolyRenewal™ polyurethane injections are specifically engineered to gently and precisely lift sinking concrete porches, providing lasting support. 

Depending on the extent of the damage and your home’s foundation type, we may also incorporate foundation repair solutions, such as foundation piers

How to Fix a Sinking Porch 

Ohio Basement Systems’ exclusive PolyRenewal™ system gently and effectively lifts and stabilizes your concrete, eliminating the need for a complete slab replacement. Here’s a step-by-step overview of how it works:

  • Inspect and identify the causes of the damage and plan the appropriate repair. 
  • Drill small, penny-sized holes into the sunken sections of the concrete. 
  • Insert custom valves into the holes, enabling the foam injection. 
  • Mix a two-part polyurethane foam. 
  • Inject foam below the concrete through the valves. 
  • Allow the foam to expand, fill the voids, lift the concrete, and cure (approximately 15 minutes). 
  • Remove the valves once the desired lift is achieved. 
  • Fill and patch the holes for a seamless finish. 
  • Seal cracks and joints for further damage protection. 
  • Provide annual maintenance to ensure the longevity of the repair. 

PolyRenewal™ excels at accurately lifting concrete without the need for extensive demolition. Our customized foam solution for sinking porches far surpasses basic mudjacking in effectiveness and durability.

Why Address a Sinking Porch Now 

There are several reasons why addressing a sinking porch is crucial: 

  • Immediate Safety: A sinking or sloped porch poses a safety hazard, especially for older visitors and those with mobility challenges. Lifting it eliminates the risk of tripping. 
  • Prevent Further Damage: Allowing the porch to remain uneven accelerates the formation of cracks and deterioration as the settled section bears additional weight. Early intervention can prevent extensive damage and costly repairs. 
  • Avoid Water Intrusion: If the damage causes the porch to slope toward the house, it can lead to water damage to the siding and potential leaks into your home. Proper drainage should direct water away from the house. 
  • Maintain Property Value: Addressing the issue eliminates an eyesore and enhances the aesthetics of your home’s entrance, helping to maintain or even increase your property’s value. 
  • Protect Your Foundation: The same factors that cause a sinking porch, such as soil erosion, can impact your home’s foundation. Timely and proper porch repair contributes to protecting your foundation. 
  • Improve Functionality: A sloped porch loses functionality, making it less usable. Concrete lifting and other repairs restore the porch’s functionality, making it safe and practical. 

Ohio Basement Systems’ exclusive solutions for sinking porches provide comprehensive and long-lasting remedies. Our superior products outshine those offered by big-box stores and other companies, ensuring your porch is restored to its best condition.
