Sinking Porch

A sinking porch is not just about appearance—it can pose a serious safety hazard, especially for older visitors who may be more prone to tripping and falling. 

Sinking porches can stem from a range of causes, from soil erosion to natural settling. Ignoring these problems can lead to extensive damage and costly repairs. 

At Baker’s Waterproofing, we utilize advanced technology and specialized expertise to deliver top-tier solutions for your sinking porch. Our state-of-the-art SettleStop™ PolyRenewal™ Injection concrete lifting technique adeptly tackles these issues, ensuring the longevity and security of both your porch and home. 

Discover more about concrete issues, such as sinking porches, and the critical role of professional concrete lifting solutions for ensuring lasting protection. 

What Is a Sinking Porch? 

A sinking porch is a prevalent issue characterized by the porch settling or descending, resulting in an uneven or slanted surface. 

This problem frequently arises from unstable foundation soils or other foundation issues, leading to cracks, tilting, and misalignment in the porch’s structure. Not only is this visually unappealing, but it can also pose a danger by creating tripping hazards. 

Addressing these concerns promptly demands the expertise of professionals to prevent further damage and maintain the structural integrity of your residence. If you notice any of these issues, contact Baker’s Waterproofing

Why Your Home Has a Sinking Porch 

Various factors contribute to sinking concrete porches, including: 

  • Gradual Soil Compression: As time passes, areas beneath the porch experience gradual expansive soil compaction, leading to uneven settling. This is a significant contributor to porch sinking. 
  • Erosion by Water Flow: Water flow beneath the porch can lead to soil erosion, causing sections to sink. This process can be worsened by downspouts directing rainwater too close to the porch. 
  • Rainfall Excess or Flooding: Floods can wash away the soil beneath a porch section, resulting in sinking. 
  • Freeze-thaw Dynamics: Repeated cycles of freezing and thawing in the ground, particularly in expansive soils beneath uneven porch areas, can play a role in sinking. 
  • Tree Root Expansion: Trees extracting moisture from the soil near a porch’s foundation can lead to minor settling on one side. The tree roots cause problems by shifting the soil and exerting pressure on the porch, compromising its support. 
  • Construction Errors in Concrete Work: Mistakes in concrete pouring or curing during construction can create vulnerabilities. Over time, this can lead to cracking, shifting, or sinking of the concrete due to inadequate support. 

Neglecting to resolve these issues may lead to escalated deterioration, potentially impacting both the porch and the home’s foundation.  

Can You Fix a Sinking Porch? 

Yes, it is possible to rectify a sinking porch. However, addressing this issue requires a comprehensive approach to home restoration. A meticulous assessment and a holistic remedy are crucial to effectively tackle the underlying causes. 

While a quick-fix method might offer temporary respite, it cannot guarantee enduring stability and safety. We strongly advise against attempting DIY repair projects or alternative techniques like mudjacking

At Baker’s Waterproofing, we utilize a tried-and-tested proprietary solution that targets the core issue, whether it’s eroding soil, tree root damage, or another concern. Our PolyRenewal™ polyurethane injections are specially formulated to gently and precisely lift a sinking concrete porch, ensuring long-lasting support. 

Depending on the extent of the damage and the foundation type of your home, we might also implement foundation repair strategies, such as foundation piers

How to Fix a Sinking Porch 

Baker’s Waterproofing offers the exclusive SettleStop™ PolyRenewal™ Injection system, providing a delicate approach to raise and secure your concrete without necessitating a full-scale replacement.

The process involves the following:  

  • Conduct a thorough examination to identify the underlying cause and develop a repair strategy. 
  • Drill small holes in the sunken concrete areas. 
  • Insert custom valves for controlled foam injection. 
  • Combine specialized polyurethane components for optimal performance. 
  • Pump mixture through valves for rapid expansion. 
  • Foam solidifies in about 15 minutes, effectively lifting the slab. 
  • Remove valves and patch holes. 
  • Seal all cracks for water resistance. 
  • Routine maintenance plans extend the repair lifespan. 

PolyRenewal™ offers precise concrete lifting, eliminating the necessity for extensive demolition. Our customized foam solution excels in fixing sinking porches, outperforming traditional mudjacking methods.

Why Address a Sinking Porch Now 

Correcting a sinking porch is crucial for a variety of reasons, such as: 

  • Safety Concerns: A sinking, sloped porch presents a safety hazard, particularly for older individuals or those with mobility challenges. Elevating it removes this potential tripping risk. 
  • Preventing Further Structural Damage: Leaving the porch uneven accelerates the development of cracks and overall deterioration, as the settled section bears additional weight. Early intervention halts extensive damage and costly repairs. 
  • Mitigating Water Intrusion: If the damage causes the porch to slope toward the home, it may result in water damage on the siding and potential interior leaks. Proper drainage away from the home is imperative. 
  • Enhancing Curb Appeal and Property Value: Resolving the issue boosts the visual allure of your home’s entrance and contributes to its overall value. 
  • Preserving Your Home’s Foundation: The same factors causing a sinking porch, such as soil erosion, can also affect your home’s foundation. Professional porch repairs play a crucial role in safeguarding it. 
  • Restoring Functionality: A sloped porch loses its intended purpose. Concrete lifting and other necessary repairs reinstate the porch to a functional state. 

Baker’s Waterproofing provides exclusive sinking porch solutions that deliver thorough and long-lasting outcomes. Our premium products outshine those available in large retail stores or provided by other companies.

Homeowner’s insurance typically doesn’t cover concrete porch repair because sinking is considered gradual settlement damage.  

To confirm, contact your insurance carrier to review your policy’s specifics. The most common reason for concrete porch sinking is soil erosion, which can be caused by heavy rainfall, poor drainage, or tree roots. Other causes of concrete porch sinking include improper construction, soil compaction, foundation settlement, and freeze/thaw cycles.  

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