Sinking Porch

If your porch has begun to sink and crack, you’re not only dealing with an aesthetic concern, but also a safety hazard that could indicate other issues. A noticeable slope to your porch increases the risk of accidents, especially for older individuals and those with limited mobility.

Sinking porches can be attributed to factors like soil erosion, compaction, and settling. Left unchecked, these factors may lead to significant damage and expensive repairs not only to your porch, but also your foundation or other concrete structures.

Bay Area Underpinning, utilizing advanced techniques and specialized services, presents optimal solutions for your sinking porch challenges. Our cutting-edge SettleStop PolyRenewal™ concrete lifting procedure addresses these problems effectively, ensuring the prolonged security and health of your porch and residence.

This page will help you understand more about common concrete challenges such as sinking porches and why professional intervention is crucial for the lasting stability of your porch.

What’s Behind a Sinking Porch?

A sinking or sloped porch is frequently evidenced by a noticeable drop or movement from its initial elevation.

This occurrence is often linked to inherent soil issues or foundation instabilities, leading to cracking, tilting, and misalignment in the porch. Apart from diminishing the appearance, it also brings about safety threats.

Reasons for a Sinking Porch at Your Residence

  • Soil Settlement: Gradual soil compression can lead to uneven porch levels.
  • Erosion: Water movement underneath can erode soil, triggering sinking.
  • Heavy Rainfall or Deluges: These can erode the foundational soil, leading to sinking.
  • Temperature Fluctuations: Regular freezing and melting of the ground can influence sinking.
  • Root Interference: Trees extracting moisture from nearby soil can affect soil stability.
  • Construction Flaws: Inadequate concrete work can foster weaknesses, causing the porch to move over time.

Procrastination can exacerbate the problem, jeopardizing both the porch and the house’s foundational structure. Promptness is crucial.

Is There a Remedy for a Sinking Porch?

Absolutely! A sinking porch can be fixed.

However, a holistic approach, considering all foundational aspects, is key.

We advise against temporary DIY solutions or outdated techniques like mudjacking.

Bay Area Underpinning employs the trusted PolyRenewal™ injections, meticulously crafted to lift and secure sinking concrete porches. Depending on the damage scale and foundational type, other solutions like foundational piers might also be utilized.
