The Ultimate Guide to Concrete Lifting

By Leah Leitow

Keeping your concrete surfaces level and safe is crucial, but it’s frustrating when your driveway, sidewalk, or patio starts to show signs of sinking or cracking.

These issues often sneak up on us, caused by soil erosion, water damage, or just the effects of time. These problems can feel overwhelming—not only do they pose safety risks, but they can also affect your home’s appearance and value.

In this guide, we’ll walk through the signs of uneven concrete and discuss the best ways to fix it so you can feel confident that your home is safe and well-maintained.

Let’s take the first step toward solving the problem together.

What Is Concrete Lifting and Leveling?

Concrete lifting and leveling involve raising and stabilizing sunken or uneven concrete slabs to restore them to their original position.

Uneven concrete can occur due to a variety of reasons, such as soil settlement, erosion, or water infiltration beneath the surface. When concrete sinks or becomes uneven, it can create safety hazards and lead to further damage.

There are several methods for lifting and leveling concrete, depending on the severity of the problem and its underlying cause. Common techniques include:

  • Polyurethane Foam Injection: This method involves injecting a lightweight, expanding polyurethane foam under the sunken concrete slab. As the foam expands, it fills any voids and lifts the concrete back to its original level. This technique is fast, minimally invasive, and effective for most types of concrete surfaces.
  • Mudjacking: Also known as slab jacking, this technique involves pumping a slurry of cement, sand, and water beneath the slab to raise it back to its original position. Mudjacking may not be suitable for all situations and can wash out easily.
  • Concrete Resurfacing: When concrete surfaces are only slightly uneven or damaged, resurfacing can provide a fresh, smooth layer over the existing slab. This method enhances appearance but doesn’t address underlying stability issues.
  • Piering Solutions: In cases where the underlying soil has caused severe settling of porches, piers may be installed beneath the concrete to provide additional support and prevent further sinking.

Whether you’re dealing with a sinking driveway, an uneven sidewalk, or a sloping patio, Groundworks has the expertise and tools to provide a lasting solution. Explore the following sections to learn more about concrete lifting and leveling options that can restore your surfaces and maintain the value and safety of your home.

Why Does Concrete Crack?: The Top 7 Causes

Concrete might look tough, but it’s got its weaknesses, too! From shifting soils to harsh weather, cracks appear for many reasons. We’re breaking down the top 7 causes so you can keep your concrete looking smooth and strong.

  • Soil Characteristics
  • Water Erosion
  • Root Intrusion
  • Drought Conditions
  • Improper Installation
  • Excessive Weight
  • Freeze-Thaw Cycles

Concrete can crack and sustain damage for many reasons, and it’s important to diagnose these causes to implement the best solution properly.

What Is Concrete Made Of?

Concrete is a versatile and durable building material with several key ingredients that form a strong, solid mass. Here’s a quick breakdown of what goes into making concrete:

  • Cement: The binding agent that holds the mixture together. Typically, Portland cement is used, which hardens when mixed with water.
  • Water: Reacts with cement to form a paste that coats and binds the aggregates. The water-to-cement ratio is crucial for determining the concrete’s strength and durability.
  • Aggregates: Coarse materials like gravel, crushed stone, and sand provide bulk and stability. Aggregates comprise most of the concrete mix and are essential for its strength.
  • Additives or Admixtures: Chemical additives may be included to modify the properties of concrete, such as accelerating curing time, improving workability, or enhancing durability against extreme weather.

Concrete’s unique composition allows it to be molded into various shapes, making it a popular choice for construction projects worldwide. Understanding its ingredients helps in selecting the right mix for specific applications, ensuring optimal performance and longevity.

Concrete Crack Inspection Guide

Regular concrete crack inspections are essential for maintaining your home’s safety and stability. They help identify minor issues before they become major problems, saving you time and money in the long run.

Depending on the type of crack and the underlying cause, different inspection methods are needed to assess the situation accurately. From surface cracks to deeper structural issues, knowing which inspection is right for your specific problem is the first step toward a proper repair.

Concrete Repair vs. Replacement: Which Do You Need?

Deciding between repairing or replacing your concrete can feel like choosing between a quick patch-up and a full-blown makeover.

If you’re staring at cracks, chips, or uneven slabs and wondering which way to go, it comes down to the extent of the damage, your budget, and how long you want the fix to last.

Making the right call now can save you from bigger headaches (and costs) down the road.

We called Alpha on recommendation from a neighbor after experiencing water damage in our crawlspace. Scheduling and quote was fast & straightforward, with helpful "what to expect" info ahead of time and notifications/reminders in advance of actions. The end result is a clean, sealed crawlspace that has resolved our moisture issues, with the added benefit of limiting entry points for pests. Having this professionally done gives us great peace of mind that this 100yo house is ready for another 100 years. Another contractor has already been under the house for unrelated work and was very pleased to have a humidity-controlled, easily-lit, and most importantly *clean* area to work. The estimator Johnnie was pleasant and took time to explain what their proposed solution would (and wouldn't) accomplish, and presented multiple options to address our immediate concerns (moisture damage) along with how we could establish a baseline and check back in the future for foundation settling/etc. The job foreman, Brett, and his crew were great from start to finish. Communication was precise & thorough, work was prompt, and the results speak for themselves. We knew right up front that we'd have to have an electrician come in with them to run a circuit for the dehumidifier & sump pump, but we didn't know until the job started that a plumber also needed move some pipes out of the way. That miscommunication led to a bit of frustration, but the Production Manager, Daniel, reached out to me and went above & beyond to make sure I walked away happy not just with the job (which I already was), but also had a good lasting impression of the experience and Alpha's commitment to customer service and standing behind their work. Would absolutely recommend this location of Alpha Foundations, and indeed I intend to have them back out in the future to investigate/remediate settlement issues now that my emergency problem is fixed. Thanks again!

Concrete Leveling FAQs

The effectiveness of concrete lifting in repairing cracks varies based on the severity of the damage. For minor cracks, the lifting process can significantly diminish their visibility. In some cases, the elevation of the concrete may be sufficient to completely close small cracks.

However, when dealing with extensive or severe cracks, lifting alone may not be adequate. In such instances, complete replacement of the concrete section might be the only viable solution to fully address the problem.

It depends on the method selected. Polyurethane foam injection addresses the soil instability or voids under the slab by stabilizing the soil beneath it. 

Protect your home’s concrete surfaces through sealing techniques, ensuring proper drainage to avoid erosion, evenly distributing weight, and regular inspection and maintenance.
