Sinking Porch

A sinking porch isn’t merely an aesthetic flaw. Its uneven lean poses hazards, increasing the likelihood of accidents, especially for children and the elderly. 

Various causes, such as soil erosion and settling, can lead to porches sinking. Overlooking these issues can result in substantial damage and hefty repair costs. 

Foundation Recovery Systems, equipped with modern technology and specialized methods, provides ideal solutions to address your sinking porch issues. We use the unparalleled SettleStop™ PolyRenewal™ concrete lifting method, ensuring your porch’s longevity and your household’s safety. 

This page offers insights into common concrete issues, like sinking porches, and underscores the importance of expert intervention for lasting protection. 

What Is a Sinking Porch?  

Homeowners frequently observe their porches slowly descending or moving from their initial positions, indicating a sinking porch. 

Such problems mainly arise from soil-related complications. These problems can manifest as structural challenges like cracks, tilting, and porch misalignment. More than being unsightly, they present real safety threats, such as increased tripping risks. 

A sinking porch can also be related to other concrete issues like: 

Addressing these promptly and relying on expert assistance is vital to halt further damage and ensure your home’s structural well-being. 

If you notice any of these signs, contact Foundation Recovery Systems. 

Why Your Home Has a Sinking Porch  

Various factors can result in a concrete porch sinking: 

  • Soil Compression: Over time, the soil underneath parts of the porch may naturally compress, contrasting with other stable areas. This uneven compression frequently results in porch sinking. 
  • Soil Erosion: Water flow below the porch can erode the soil over time, causing specific sections to sink. Improper downspout placement intensifies this erosion. 
  • Heavy Rainfall or Flooding: Extreme rainfall or flooding can wash away supporting soil, leading to depressions in the porch. 
  • Freeze-Thaw Cycles: The repetitive freezing and thawing of ground, especially in expansive soils, can result in parts of the porch lowering. 
  • Tree Root Movement: Trees extracting moisture near the porch’s foundation can lead to uneven settling. Their roots can also push against and compromise the porch’s foundational support. 
  • Improper Concrete Installation: If concrete isn’t properly set during construction, it can weaken and eventually crack, shift, or sink due to inadequate foundation support. 

Ignoring these elements can exacerbate the damage, endangering both the porch and the home’s foundational stability. It’s essential to tackle these concerns head-on for durable and efficient outcomes. 

Can You Fix a Sinking Porch?  

Yes, repairing a sinking porch is possible. 

Addressing this issue requires a comprehensive home repair approach. An inspection combined with a robust solution is necessary to effectively manage the underlying causes. 

While temporary repairs might provide short-term relief, they aren’t reliable for long-term stability. DIY methods and mudjacking are not recommended. 

Foundation Recovery Systems uses a proven, specialized solution to handle the main problem, be it soil erosion or tree root issues. Our PolyRenewal™ injections are designed to delicately yet accurately lift a sinking concrete porch, guaranteeing continued stability. 

Depending on the extent of damage and your home’s foundation health, we might also employ foundational repair strategies such as foundation piers

How to Fix a Sinking Porch  

Foundation Recovery Systems’ unique PolyRenewal™ system can lift and stabilize your concrete without the need for a complete replacement. 

The process is as follows: 

  • Our experts conduct an inspection to identify the root cause and strategize the repair. 
  • Small, dime-sized holes are drilled into the sunken concrete areas. 
  • Special ports are inserted into these holes for foam injection. 
  • We combine two proprietary polyurethane foam elements. 
  • This foam is injected via the ports, expanding rapidly beneath. 
  • The robust foam solidifies in roughly 15 minutes, raising the slab during this process. 
  • We remove the valves and seal the holes. 
  • Any cracks are sealed to ward off potential water damage. 
  • Routine maintenance is recommended to enhance the repair’s lifespan. 

The PolyRenewal™ method offers precise concrete lifting without extensive disruption, proving more effective than traditional mudjacking.

Why It’s Essential to Address a Sinking Porch Immediately 

There are multiple vital reasons to address a sinking porch without delay: 

  • Safety Comes First: A declining or sinking porch presents genuine risks, especially for the elderly or those facing mobility issues. Addressing the misalignment minimizes the danger of trips and falls. 
  • Avoid Further Damage: A neglected, imbalanced porch can suffer from heightened wear and tear, leading to pronounced cracks and degradation. Early intervention can prevent extensive damage and costly repairs. 
  • Protect Against Water Intrusion: If a porch leans towards the home, it can channel water into the structure, risking damage to the siding and potential leaks. The goal is to have water flow away from the porch. 
  • Maintain Property Value: Addressing the evident issue not only uplifts your home’s appearance but also sustains its real estate value. 
  • Protect Your Home’s Structural Integrity: Elements that lead to a porch sinking, such as soil erosion, might also threaten your home’s foundation. Addressing porch issues in a timely manner also fortifies the foundation’s strength. 
  • Restore Full Utility: A tilted porch reduces its usability. Through expert concrete lifting and subsequent repairs, you can reclaim its original purpose.

Overwatering plants near the porch or having plants that retain a lot of water can exacerbate soil erosion. Additionally, poor landscaping design can lead to water pooling near the porch foundation. 

Yes. A sinking porch can deter potential buyers due to concerns about structural issues, leading to a reduction in property value. 

This varies by insurance policy. Some homeowner’s insurance policies might cover sinking porches, especially if it’s caused by a covered peril, but many do not. Always check with your insurance provider. 

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