Sinking Porch 

A sinking porch is more than an eyesore. Its uneven nature poses potential tripping dangers, especially among kids and seniors. 

Issues like soil erosion and settling can be the culprits behind a sinking porch. Neglecting these problems can spiral into significant damage and hefty repair bills. 

Innovative Basement Authority, armed with state-of-the-art technology and expertise, offers tailored solutions for your sinking porch challenges. Our SettleStop™ PolyRenewal™ concrete lifting technique guarantees a long-lasting and safe porch. 

Explore this page to understand more about common concrete problems, including sinking porches, and learn why professional intervention is crucial for lasting safeguarding. 

What Is a Sinking Porch? 

It’s not uncommon for homeowners to notice their porches gradually sinking or shifting from their original placement, signaling a sinking porch issue. 

Primarily stemming from soil complications, these concerns can manifest in structural defects like cracks, tilting, or a misaligned porch. Beyond the aesthetic impact, these problems pose safety hazards, increasing the chances of tripping. 

A sinking porch might also be symptomatic of other concrete challenges such as: 

  • Cracked concrete 
  • Sinking steps 
  • Sinking concrete slab 
  • Cracked sidewalks 
  • Cracked driveway 
  • Cracked pool deck 
  • Concrete pitting, flaking, and staining 

It’s essential to address these issues quickly.  Seek professional help to prevent further damage and ensure your home remains structurally sound. 

Should you observe any of these symptoms, reach out to Innovative Basement Authority. 

Why Your Home Has a Sinking Porch 

There are multiple reasons why a concrete porch might start sinking: 

  • Soil Compaction: The natural compaction of soil beneath a section of the porch over time, contrasted with firm ground elsewhere, can lead to uneven settling, which is a primary cause of sinking porches. 
  • Soil Erosion: If water flows beneath the porch, it can wear away the soil, leading one part to drop. This is especially true if downspouts discharge rainwater too near to the porch, intensifying erosion. 
  • Heavy Rainfall or Flooding: Soil underneath the porch can be swept away by floods, resulting in the porch settling lower. 
  • Freeze-Thaw Effects: The continuous process of the ground freezing and thawing, especially in soils that expand, can lead to sinking in certain parts of the porch. 
  • Tree Root Interference: Tree roots can absorb moisture from the ground near the porch foundation, causing unequal settling. These roots can also move the soil and apply pressure on the porch, affecting its structural integrity. 
  • Faulty Concrete Work: Inadequate concrete pouring or curing during the building phase can result in weak spots. As a result, the concrete might crack, displace, or sink due to insufficient support over the years. 

Addressing these problems promptly is crucial. If neglected, the damage can spread, jeopardizing both the porch and the home’s foundation. This can lead to costly and comprehensive repairs.  

Can You Fix a Sinking Porch? 

Absolutely, repairing a sinking porch is feasible. 

However, a whole home repair strategy is essential to tackle this problem. It’s vital to conduct a thorough inspection and adopt a complete solution to effectively tackle the root causes. 

Opting for a patchwork solution may offer a short-term fix but will likely fall short in ensuring prolonged stability and safety. We advise against DIY remedies and techniques like mudjacking. 

At Innovative Basement Authority, we utilize a tested, unique method that targets the fundamental issues, whether that’s soil erosion, tree root interference, or another factor. Our PolyRenewal™ polyurethane injections are crafted to gently and accurately elevate a sinking concrete porch, ensuring enduring stability. 

Depending on the damage severity and your home’s foundation, we might also incorporate foundation repair techniques, such as foundation piers. 

How to Fix a Sinking Porch 

Innovative Basement Authority’s specialized PolyRenewal™ system is adept at lifting and stabilizing your concrete without the hefty cost and inconvenience of complete replacement. 

Here is a look at our process:  

  • Our team conducts an inspection to identify the source of the damage and devise a repair strategy. 
  • We drill small holes, about the size of a penny, into the sunken areas of the concrete. 
  • Specialized ports are placed into these holes, allowing for foam injection beneath. 
  • We combine two unique polyurethane foam elements. 
  • This foam is then introduced through the ports, expanding swiftly. 
  • Within 15 minutes, the high-density foam solidifies, raising the slab in the process. 
  • Following this, the valves are taken out and the drilled holes are sealed. 
  • All cracks are sealed to stop potential water complications. 
  • Consistent upkeep ensures the durability of our repairs. 

PolyRenewal™ accurately lifts concrete without intensive demolition. Our tailored foam approach offers a superior fix for sinking porches, outperforming traditional mudjacking. Contact Innovative Basement Authority to book a free inspection and explore this cutting-edge technique. 

Why Address a Sinking Porch Now  

There are several compelling reasons to address a sinking porch without delay: 

  • Safety First: A declining or slanted porch poses safety risks, particularly for elderly guests or those with mobility challenges. Raising it eliminates potential tripping hazards. 
  • Halt Additional Damage: An unbalanced porch can quickly develop cracks and deteriorate, as the lowered section bears extra weight. Taking early action can stave off extensive harm and expensive restorations. 
  • Guard Against Water Damage: Should the porch tilt towards your home due to damage, it might direct water towards your residence, damaging the siding and potentially causing leaks. Ideally, water should drain away from the house. 
  • Preserve Home Value: Repairing the issue not only removes an unsightly defect but also enhances the visual appeal of your home’s frontage, thereby helping to sustain its market value. 
  • Defend Your Home’s Foundation: Factors like soil erosion, which can cause a porch to sink, may also threaten the foundation of your home. Repairing the porch in a timely manner is a step towards safeguarding your home’s foundation. 
  • Restoration of Functionality: A porch that’s not level compromises its utility. Concrete elevation and other related fixes restore its functionality.

Not always. Depending on the severity and the cause of the sinking, lifting the porch or stabilizing the foundation may suffice. In extreme cases, replacement might be the best option.  

Addressing a sinking porch as soon as you notice it is crucial to prevent further damage, increased repair costs, and potential safety hazards.  

Absolutely. Proper water drainage is crucial to prevent further sinking. Make sure downspouts direct water away from the porch and that the surrounding land slopes away from the structure.
