Sinking Porch 

A front porch stands as a family’s sanctuary for relaxation and bonding. However, when it begins to sink, it not only disrupts the peace but also diminishes its aesthetic appeal. 

Regrettably, a sinking porch can signal underlying issues. Potential problems within the soil beneath might jeopardize other areas of the home if neglected. 

Using industry-leading concrete lifting techniques, our goal is always to restore the safety of your home. This page provides insights into why your porch is sinking and how you can fix it. 

What Is a Sinking Porch? 

Identifying a sinking porch is simple: watch out for a clear decline or alteration in its level. Commonly, this is rooted in foundational or soil challenges, potentially leading to visible cracks on the porch. 

Porch damage can lead to potential stumbling risks for your family. Beyond that, they can trigger larger household complications, such as foundational concerns. 

A sinking porch could also present itself with other concrete issues like: 

  • Cracked sidewalk 
  • Cracked pool deck 
  • Cracked driveway 
  • Cracked patio 
  • Sinking stairs 

Tackling these issues early, and with seasoned professionals, is pivotal to maintaining your home’s structural integrity. Connect with Alpha Foundations at the earliest sign of such problems. 

Reasons Behind a Sinking Porch 

Typically, a porch sinks when the ground beneath it is compromised. This can be due to environmental factors or construction errors. Common causes include: 

  • Soil Compression: Uneven soil settling, where some parts are compressed while others stay unchanged, leads to many porches sinking. 
  • Ground Erosion: Under-porch water movement can erode soil, making areas of the porch sag. Sandy soils in our state are especially susceptible to this issue. 
  • Heavy Downpours or Floods: Thunderstorms and hurricanes erode the soil under concrete, especially if flooding occurs. Weak soil makes the porch sink into the weakened ground. 
  • Temperature Swings: Regular soil freezing and thawing can cause erratic settling. 
  • Root Disruption: Trees extracting moisture near a porch can lead to uneven settling. Large tree roots may also impact the porch’s stability by pushing up on the structure. 
  • Concrete Flaws: Errors during concrete placement can result in its susceptibility to cracks, shifts, or sinking. 

Timely intervention can prevent further damage, ensuring not just the porch’s safety but also the home’s foundational integrity. Immediate attention paves the way for durable repair and protection. 

Is It Possible to Restore a Sinking Porch? 

Absolutely, mending a sinking porch is achievable. The key lies in adopting a holistic approach to concrete repair. Enlisting expert services is crucial for effective mitigation. 

While DIY solutions might offer temporary relief, they often fall short of lasting stability. Traditional methods like mudjacking aren’t preferable either because they don’t actually solve the underlying problem. 

Alpha Foundations uses a modern method that addresses core causes behind concrete problems, be it soil erosion or tree roots. It’s called polyurethane foam injection, and it makes concrete lifting more efficient than ever

Based on the extent of damage and your home’s foundation layout, we may integrate other foundational repair techniques. 

Approach to Restoring a Sinking Porch 

Alpha Foundations’ PolyRenewal™ system proficiently raises and strengthens your concrete, eliminating the need for total replacement. The procedure involves: 

  • A professional inspection to pinpoint the root causes and decide on the best course of action. 
  • Drilling penny-sized holes into the damaged porch sections. 
  • Inserting specialized injection equipment into these holes. 
  • Preparing our proprietary two-part polymer foam to produce PolyRenewal™. 
  • Injecting PolyRenewal™ beneath the sinking porch. 
  • The foam expands swiftly, filling voids, elevating the concrete, and curing in roughly 15 minutes. 
  • This raises the concrete and reinforces the ground underneath simultaneously. 
  • Removal of injection ports and sealing the holes. 
  • Ensuring cracks are filled to block future water entry. 
  • Periodical checks and maintenance to ensure the system continues working. 

Our foam technique rejuvenates a sinking porch, surpassing conventional methods. Engage with Alpha Foundations to leverage this groundbreaking approach. 

Significance of Promptly Addressing a Sinking Porch 

Apart from the immediate repair benefits, addressing the issue also brings long-term advantages. By correcting a sinking porch, you can: 

  • Ensure Safety: A descending porch can be hazardous, especially to seniors or those with mobility issues. Its restoration can prevent potential mishaps. 
  • Prevent Further Damage: Overlooking a sinking porch speeds up its wear as the affected area sustains more pressure. Timely concrete repair can avert extensive harm and costly fixes. 
  • Stop Water Intrusion: A sloping porch might channel water toward your home, threatening your exterior or your basement. Water routing away from the home is essential. 
  • Maintain Property Value: Remove unattractive problems and uplift your property’s charm. Addressing a sinking porch can safeguard your property’s worth. 
  • Regain Functionality: A dysfunctional porch diminishes its usability. Concrete elevation restores your porch and makes it possible to enjoy the space without issues.
