Sinking Porch 

A sinking porch can be unsightly and may pose safety risks, especially for elderly visitors. When porches sink, it’s usually due to soil erosion and settling. If left unattended, this issue can lead to significant damage and costly repairs. 

At Indiana Foundation Service, we specialize in addressing sinking porch concerns. Our team utilizes cutting-edge technology and our SettleStop™ PolyRenewal™ concrete lifting method to efficiently resolve concrete issues, ensuring your home’s safety and durability. 

On this page, we aim to provide valuable insights into common concrete problems, such as sinking porches, and stress the importance of seeking professional repairs to ensure long-lasting protection. 

What Is a Sinking Porch? 

A sinking porch is a common issue that occurs when the porch visibly settles or lowers from its original position. This can happen due to soil problems or foundation instability, resulting in structural cracks, tilting, and misalignment. Sinking concrete affects your home’s appearance and poses safety risks, such as tripping. 

A sinking porch can be accompanied by other concrete problems, such as: 

Concrete problems should be addressed promptly with professional assistance to prevent further damage and ensure your home’s safety.

Why Your Home Has a Sinking Porch 

Causes of a sinking concrete porch include: 

  • Soil Settlement: Over time, the soil under one part of the porch naturally compacts, while the ground under another area remains firm. 
  • Soil Erosion: Water flowing under the porch can erode the soil, causing one section to sink. 
  • Excessive Rain or Flooding: A flood can wash away soil under a section of the porch, causing it to sink. 
  • Freeze-thaw Cycles: Repeated freezing and thawing of the ground—especially in expansive soils—under uneven porch areas can cause it to sink. 
  • Tree Roots: Trees soaking up moisture from the soil near a porch’s foundation can cause uneven settling on one side. 
  • Poor Concrete Pouring/Curing: Improper concrete pouring or curing during construction can create vulnerabilities, and over time, the concrete can crack, shift, or sink due to inadequate support. 

Ignoring these issues can escalate the damage, affecting the porch and the home’s foundation and requiring extensive repairs. Swift action is vital to lasting repairs and protection. 

Can You Fix a Sinking Porch? 

Fixing a sinking porch requires a comprehensive approach. A thorough inspection and whole-home solution are needed to address the underlying causes effectively. 

Avoiding piecemeal repairs or DIY methods like mudjacking is crucial for long-term stability and safety. 

At Indiana Foundation Service, we use our proprietary PolyRenewal™ polyurethane injections to gently and precisely lift a sinking concrete porch. These injections address the root cause, such as eroding soil or tree root damage, providing lasting support. 

How to Fix a Sinking Porch 

Indiana Foundation Service offers the PolyRenewal™ system to raise and stabilize concrete without complete replacement. Here’s how it works: 

  • Inspect and plan the repair. 
  • Drill holes into the sunken sections of the concrete. 
  • Inject foam underneath through custom valves. 
  • Mix and pump polyurethane foam below the slab. 
  • Foam expands rapidly, lifting the slab. 
  • Foam hardens within 15 minutes, solidifying the lift. 
  • Remove valves and patch holes. 
  • Seal cracks to prevent water issues. 
  • Regular maintenance ensures long-lasting repairs. 

PolyRenewal™ lifts concrete accurately without major demolition. Our foam solution repairs sinking concrete porches better than mudjacking. Contact Indiana Foundation Service for a free inspection and to learn more about this innovative process.

The cost of sinking porch repair can vary based on factors like the porch’s size, the severity of the damage, and the most suitable solution. Indiana Foundation Service provides free inspections, transparent pricing, and financing options.

Homeowner’s insurance generally does not cover sinking porch repairs because it is considered gradual settlement damage, a type of maintenance issue often excluded from policies. We recommend reviewing the details of your policy with your insurance carrier. Indiana Foundation Service offers free inspections, estimates, and flexible financing options to assist you with repair costs.
