Crawl Space Encapsulation Experts

Professional Concrete Leveling in Milwaukee, WI

Uneven concrete around your home isn’t just a cosmetic issue. Sinking driveways, sloped patios, and cracked sidewalks can create tripping hazards, drainage problems, and long-term damage to your property. The longer the concrete stays out of level, the more it can shift, sink, or break apart. This raises both the risk and the repair cost.

At Accurate Basement Repair, we provide professional concrete leveling services that lift and support sunken slabs using polyurethane foam injection, with no messy demolition or extended downtime. Whether you’re dealing with a sloped garage floor or a sidewalk that has become a hazard, our team will evaluate the issue and recommend a fix that works for your home.

It's More Than An Eyesore

Ready to Poly Lift your uneven concrete?

Why Uneven Concrete Is More Than Just an Eyesore

When concrete slabs sink, crack, or tilt, the problems multiply quickly and become more expensive to fix. Here’s what happens when uneven concrete is left untreated:

Safety Hazards

  • Trip and fall injuries
    Raised edges and sudden drops cause serious accidents, especially for children, elderly visitors, and delivery personnel

  • Legal liability
    Property owners' responsibility for injuries can lead to costly lawsuits and insurance claims

Property Damage

  • Poor drainage
    Low spots collect water that pools, freezes, and can seep toward your foundation

  • Foundation stress
    Sloped garage floors and patios direct water toward your home's foundation, increasing moisture damage risk

  • Structural separation
    Settling slabs pull away from structures, creating gaps and instability

Financial Impact

  • Reduced property value
    Cracked, tilted concrete makes even well-maintained homes look neglected

  • Escalating repair costs
    Minor settlement becomes major replacement if ignored

  • Insurance complications
    Some policies may not cover damage from "deferred maintenance"

Warning Signs

Signs You May Need Concrete Leveling

Most homeowners notice symptoms of concrete settlement long before they realize what’s causing it. If you’ve seen any of the following around your home, it may be time to schedule a professional inspection.

  • A cracked concrete driveway

    Cracked and Uneven Concrete

    Slabs that tilt, sink, or develop wide cracks are a common sign that the soil beneath is no longer supporting the weight. This is often seen in driveways, walkways, and patios.

  • Front porch slab settling

    Porches and Patios Pulling Away

    Gaps forming between the slab and your home’s exterior wall can indicate that the concrete has settled or shifted, creating potential for water intrusion and structural stress.

  • Water pooling in garage

    Water Pooling in Your Garage

    Sloped or sunken garage floors can allow rain or runoff to collect instead of draining properly, often pooling near the foundation or door threshold.

  • Sagging floor within a home

    Gaps Between Baseboards and Floors

    When interior concrete floors settle unevenly, you may notice separation where baseboards once sat flush with the slab, especially in finished basements or garages.

  • A walkway in front of a home that has settled a few inches and created a tripping hazard

    Raised Edges or Trip Hazards

    Uneven walkways, porch steps, or sections of sidewalk that no longer align are not only frustrating, they’re also a safety risk.

  • Entry steps getting pulled down by sinking concrete

    Sunken Areas Near Steps or Stoops

    Voids beneath small concrete slabs can cause sinking around entry points, making stairs feel off-balance or unstable.

Not sure if what you’re seeing is serious?

Our team can help. A free inspection from a Certified Foundation Specialist will identify whether your slab can be leveled and what steps are needed to restore it safely.

What Causes Concrete Slabs to Sink and Settle

Understanding why your concrete is sinking helps prevent future problems. Most settlement issues start below the surface and worsen over time due to soil conditions common throughout Milwaukee, WI.

Primary Causes in Our Service Area:

  • Soil Erosion
    Heavy rainfall, poor drainage, and seasonal storms wash away supporting soil beneath slabs. Our region's soil is particularly vulnerable during the rainy season.

  • Poor Initial Compaction
    If soil wasn't properly compacted during original construction, it continues settling under the concrete's weight, especially during our area's seasonal cycles.

  • Moisture Fluctuations
    Milwaukee, WI's climate creates dramatic soil expansion and contraction. Dry periods cause soil shrinkage, while heavy rains saturate and soften the ground.

  • Freeze-Thaw Damage
    Winter temperatures can cause repeated soil expansion and contraction, gradually pushing slabs out of alignment.

  • Heavy Load Stress
    Driveways, patios, and garage floors sink under vehicle weight, equipment storage, and constant traffic, especially when the underlying soil is compromised.

FAQs

Frequently Asked Questions:
Milwaukee, WI Concrete Leveling

If you see cracks, tripping edges, sloped sections, or gaps beneath stairs or stoops, your concrete may have settled. A concrete leveling contractor can confirm whether the slab can be lifted or if other repairs are needed.

Most residential projects are completed the same day. You can usually walk or drive on the surface within hours, depending on the size of the area and weather conditions.

Our process is designed for long-term performance. We use high-density polyurethane foam to lift and support the slab, and we address the cause of settlement to help prevent future movement.

Yes. Accurate Basement Repair provides concrete leveling services across Milwaukee, WI, Kenosha, and Racine. If you’re not sure whether we cover your neighborhood, just give us a call or check our service area.

No. The process is minimally invasive and does not require large equipment or digging. The foam expands under the slab, not across your yard, and any small drill holes are sealed once the work is complete.

The slab will likely continue to settle, which can lead to deeper cracks, wider gaps, and more expensive repairs later. Uneven concrete also increases the risk of injury, water intrusion, and structural strain if it’s near the foundation.
