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 bought a home that had a 1960s bomb shelter built into it. It has been the bane of our existence because it was always wet being it was under our breezeway and just below basement level. We hired Groundworks to help us waterproof the room which we could step into via our basement. Hopefully, this will be the fix to keep us dry for years to come. It looks like a different space that is no longer gross, wet, and mucky. I cannot praise Josh and Kendrick enough. They really had a challenge in this project. I am sure they are still sore today. The worked really hard with great communication. They were professional, just plain awesome guys! Thank you!

Excellent experience overall. I had to wait a couple of months to get work done and the scheduling department was confusing. When they did come to do the Intelijack install under our porch/hall crawl space- Larry and Felix did a really good job. I was amazed at how hard they worked , with minimal breaks and a very long day. They cleaned the site underneath porch, then dug 7 holes , laid the marble stone and fitted the jacks and install all in one day. Cleaned up and left the site spotless. Then, another crew came out to install an indoor basement french drain and vapor barrier. Again great work. Amazing team with many men: Terrance, Mohammed, Isaiah, Kevin, Melvin, Shakeem, Chino, Israel and Jay. Great work guys!!! Team players, very nice and hard workers. Quality work. Only complaint is Groundworks doesn't do any caulking of hole around drain pipe on exterior of home and the stairwell steps had to be removed in order to install drain and they didn't nail steps back into place. It would have been nice if those things could have been done. Also the new dehumidifier does make a bit of noise. They say it is very quiet, we are getting used to it though. It's not too, too loud , but definitely noticeable. As far as drain goes-So far so good. Haven't had a large enough rain storm yet to tell if problem is solved.

They crew just finished fixing my driveway and pool deck (this was from hurricane damage). Yesterday they put in some pilings to lift/support a slab on the corner of my pool deck. They did an excellent job. Both crews were very nice, friendly, and professional. I will gladly hire them again. In fact, I'll likely ask them to come back in a few months and check my foundation. I would gladly recommend them to friends, family, and neighbors.

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.
