Sunken & Settled Concrete Problems

Sunken concrete driveway before repair in Greater Chicago & Northwest Indiana

Sunken concrete can collect water and leave raised edges that become easy to trip over. Fortunately, settled concrete does not always need to be torn out and replaced. Chicago Basement Systems offers professional sunken concrete repair and concrete leveling throughout Greater Chicago & Northwest Indiana, using structural polyurethane foam to lift and stabilize settled concrete slabs.

Our concrete leveling process addresses voids and unstable areas beneath the slab, allowing sunken concrete to be carefully raised to where it should be.

Why does concrete sink?

Concrete slabs depend on the soil beneath them for support. When that soil settles, shifts, or washes away, the concrete above can sink or tilt. Concrete leveling addresses this loss of support by placing structural polyurethane foam beneath the affected slab to fill voids, stabilize the concrete, and lift it toward the proper elevation.

Settlement can develop for several reasons. Repeated freezing and thawing can cause moisture in the soil to expand and contract, while clay-rich soils can change volume as moisture levels fluctuate. Poor drainage, improper grading, and water flowing beneath or alongside a slab can also erode or soften the supporting soil.

Conditions that can contribute to sunken concrete include:

  • Soil settlement beneath the slab
  • Poorly compacted fill soil
  • Freeze-thaw cycles
  • Soil erosion and washout
  • Improper drainage or grading
  • Water collecting near concrete slabs
  • Voids beneath the concrete

Because the visible concrete is only part of the problem, Chicago Basement Systems evaluates both the slab and the conditions surrounding it before recommending sunken concrete repair.

When to Consider Sunken Concrete Repair

Concrete leveling is designed to correct settlement while preserving slabs that are still in serviceable condition. If sections of concrete around your property have dropped, tilted, or become uneven but the concrete itself is still largely intact, leveling may provide an effective alternative to complete concrete replacement.

Sunken concrete problems that may be repaired with concrete leveling include:

  • Sunken concrete slabs
  • Uneven sidewalks and walkways
  • Settled patios
  • Uneven driveway sections
  • Sunken concrete steps
  • Raised or uneven slab edges
  • Water pooling in low areas
  • Gaps or voids beneath concrete
  • Trip hazards caused by concrete settlement

A professional inspection can determine whether polyurethane foam concrete leveling is appropriate based on the condition of the slab and the pattern of settlement.

Where can sunken concrete be repaired?

Concrete settlement can occur almost anywhere a slab rests on soil. Around a home, it commonly affects driveways, sidewalks, patios, walkways, steps, and other concrete surfaces. As individual slabs settle at different rates, sections can become uneven and create noticeable dips, slopes, or raised edges.

When the affected concrete remains in serviceable condition, polyurethane foam leveling can often lift the settled sections without removing the existing slab. Correcting the elevation can create smoother transitions, reduce trip hazards, improve usability, and help address low spots where settlement has caused water to collect.

Our Approach to Sunken Concrete Repair

Chicago Basement Systems uses structural polyurethane foam to lift settled concrete. Rather than demolishing the existing slab, small access holes are drilled through the concrete so the leveling material can be placed beneath it.

How Polyurethane Foam Concrete Leveling Works

  1. Inspect the concrete: Our concrete leveling specialist evaluates the amount and pattern of settlement, the condition of the slab, surrounding drainage, and other factors that may be contributing to the problem.
  2. Drill small access holes: Strategically placed holes provide access to the voids beneath the concrete while minimizing disturbance to the existing slab.
  3. Inject structural polyurethane foam: The expanding foam flows beneath the slab, fills empty spaces, and provides support beneath the concrete.
  4. Carefully lift the slab: The settled concrete is raised in controlled stages toward the desired elevation.
  5. Patch the access holes: Once leveling is complete, the holes are patched and the work area is cleaned.

Polyurethane foam cures quickly, so many concrete leveling projects can return to normal use much sooner than concrete that has been removed and repoured. Your specialist will explain the appropriate wait time for your specific project.

Sunken Concrete Repair vs. Concrete Replacement

Replacing a concrete slab requires breaking apart and removing the existing concrete, preparing the base, pouring new concrete, and waiting for the new slab to cure. If the existing concrete is severely cracked, crumbling, or structurally deteriorated, replacement may be necessary.

However, when the slab itself remains in serviceable condition and settlement is the primary problem, polyurethane foam concrete leveling can often correct the elevation without replacing the entire slab.

Benefits of leveling existing concrete can include:

  • Less demolition and property disruption
  • Faster installation than full replacement
  • Quick-curing polyurethane foam
  • Reduced trip hazards and uneven transitions
  • Improved appearance and usability
  • Support for voids beneath the existing slab
  • Potential cost savings compared with replacement

Sunken Concrete Repair FAQs

Can sunken concrete be lifted?

Yes. If the concrete slab is largely intact but has settled or tilted, it may be a candidate for concrete leveling. Structural polyurethane foam can be injected beneath the slab to fill voids and carefully lift the concrete toward the desired elevation. This can help restore a smoother, more usable surface without full replacement.

What types of sunken concrete can be repaired?

Concrete leveling may be used for many settled concrete surfaces around a property, including sidewalks, walkways, patios, driveways, steps, and other slabs. Whether a particular area can be leveled depends on the condition of the concrete and the cause and extent of settlement.

Why does concrete sink over time?

Concrete can sink when the soil beneath a slab settles, erodes, washes away, or was not properly compacted before the concrete was installed. Changes in soil moisture, freeze-thaw cycles, poor drainage, and voids beneath the slab can also contribute to concrete settlement.

How long does polyurethane foam concrete leveling take?

Project length depends on the size of the area and the extent of settlement, but concrete leveling generally requires much less disruption than removing and replacing a slab. The polyurethane foam also cures quickly. Your concrete leveling specialist will provide project-specific information during your inspection.

When should sunken concrete be replaced instead of leveled?

Concrete leveling is designed to correct settlement, not rebuild severely deteriorated concrete. A slab that is extensively crumbled, badly fractured into many pieces, or otherwise structurally unsound may require replacement. Chicago Basement Systems can inspect the concrete and explain whether leveling or full replacement makes the most sense.
