Common Reasons Your Porch or Patio May Shift

Patios and porches sink for several reasons, primarily due to underlying issues with the soil and the environment. Here are the main causes:

  1. Soil Erosion: Water from rain, drainage, or poor irrigation can erode the soil beneath a patio or porch. As the soil washes away, it creates voids under the concrete, leading to sinking or uneven surfaces.
  2. Poor Soil Compaction: During construction, if the soil beneath the patio or porch wasn't properly compacted, it may settle over time under the weight of the concrete. This settling causes the slab to shift or sink, creating uneven areas.
  3. Heavy Load on Weak Soil: Concrete patios and porches are heavy structures. If they're built on weak, clay-heavy, or loosely packed soil, the weight of the concrete can compress the soil further, causing the slab to sink.
  4. Water Accumulation: Water pooling around the patio or porch due to improper drainage can weaken the soil. Over time, the constant moisture can cause the ground to soften, leading to settlement or sinking.
  5. Freeze-Thaw Cycles: In colder climates like St. Louis, the repeated freezing and thawing of water in the soil can cause expansion and contraction. This movement can shift or crack the concrete, leading to sinking or uneven surfaces.

  • What is porch and patio leveling, and how does it work?

    Porch and patio leveling is the process of lifting and stabilizing uneven or sinking concrete slabs. It’s typically done using polyurethane foam, which is injected underneath the slab. The foam expands, lifting the concrete back to its original level. This method is fast, minimally invasive, and provides a long-lasting solution.



  • Why is my porch or patio sinking?

    Concrete porches and patios sink for a variety of reasons, including poor soil compaction, water erosion, and soil settlement over time. Water accumulation or inadequate drainage can also cause the soil beneath your porch or patio to erode, leading to uneven surfaces.

  • How long does the leveling process take?

    Most porch and patio leveling projects can be completed in a few hours, depending on the size of the area and the extent of the sinking. Once the foam is injected and the slab is leveled, the surface is typically ready for normal use within a few hours.

  • Is leveling a more cost-effective option than replacing the entire porch or patio?

    Yes, leveling is generally much more cost-effective than a full replacement. Leveling restores the appearance and safety of your porch or patio without the high costs of demolition, removal, and new concrete installation. Additionally, it’s a quicker and less disruptive process.
