How Much Does Concrete Lifting and Leveling Cost?

Updated: Apr 8

So you keep tripping on that stubborn raised section of sidewalk leading up to your porch, or possibly even more frustrating, you keep breaking your snowblower on that section of driveway slab that has sunken ¾ of an inch that buts up to all the nice and level slabs, nearly knocking you head over heels. Like many of us, we just tolerate it because we don’t know how easy and cost effective raising and leveling that piece of concrete can be.


Our sales team is asked every day, “How much does concrete lifting and leveling cost?" Although there isn't an easy cookie-cutter answer, on average, the cost of lifting and leveling your concrete is between $7.00 and $12.00 per pound of polyurethane foam depending on a few additional factors:

  • Scope of Work

  • Size of the Void

  • Access to Work Area

  • Weather



Since we have been in the spray foam industry for over 25 years and have seen hundreds of different scenarios, we know what makes the cost go up and down with these repairs.


Let's review the average price of concrete lifting and leveling and break down factors that could affect your price. Keep in mind that when you are looking to invest in your property, it’s a good idea to get a couple of quotes from different contractors.

Costs of Leveling Concrete

HomeAdvisor states the average cost to have a property owner’s concrete leveled is between $548 - $1,341. Other sources site the average cost is $2 - $5 per square foot. While that may give you a decent idea where your costs might fall, we can dig into it a little deeper. For this article we will concentrate on concrete lifting and leveling utilizing polyurethane foam.


The cost of lifting and leveling your concrete is all based on volume. Meaning, the cost is primarily based on the cubic feet or cubic yards of material that will be required to level your concrete. This is a little more confusing than simply calculating square footage, in addition to the area, we need to consider the depth.


For example, a typical sidewalk section is 5’ x 5’, equaling 25 square feet. Now consider how deep the sidewalk section has settled. Say it has settled 1” on all four sides of the section in question. Multiple the 25 square feet by the 1” (0.083’) of depth and you will get 2.075 cubic feet or converting that into cubic yards (divide by 27) equals 0.077 cubic yards.


Depending on the density of polyurethane foam the contractor is using, they will convert the cubic yards required into the required pounds of polyurethane foam needed to fill the space to level the concrete. An average density of polyurethane foam is 120 pounds per cubic yard. Multiplying the cubic yards required by the material density will tell you how many pounds of foam are required.


So, 120#/cy x 0.077cy = 9.24 pounds of polyurethane foam needed. Most contractors will base their cost to you on a range of $7 - $12 per pound of foam required. So, this section of sidewalk slab would cost between $64.68 - $110.88. Yet, there are other factors that contribute to the cost of leveling you concrete.

How the Size of Your Concrete Affects Cost

It would be tough for contractors to survive if they went out and installed a whole bunch of $64.68 projects. Therefore, some contractors will set minimum prices regardless of the amount of work or material required.


Successful contractors will be able to defray the minimum service cost by grouping multiple projects in your area to be performed on the same day so they can service the small and large projects without minimum costs.


The opposite end of the spectrum is also true, meaning that there are economies of scale for the larger projects. Each project has a minimum amount of set up and break down time. Larger projects will have a lower cost per pound as the costs for setting up and tearing down are spread over a larger volume of work.


How Concrete Void/Gaps Affect Cost

Again, the primary cost driver is volume. The greater the elevation of lift that is required, the higher the price will be. A project with a bunch of slabs that only need lifted ½” will be far less than a project that needs the same number of slabs lifted 3”.


Another consideration beyond the distance in elevation between the slabs is if there is a void under the area in question. Some slabs may only settle 2” and get hung up on something but there will be a 4” void under the slab that may have been caused by flooding or water runoff. The entire void would need to be filled to be able to successfully lift and level the slab in question. In this example, the number of pounds required would be based on a total of 6”.


Experienced contractors will be able to recognize the necessity to consider the additionally void fill. Although, there are some instances where the void is completely unforeseen. At this point, the contractor and owner would need to discuss what the additional requirements are prior to proceeding with the work.


How the Access To Your Concrete Area Affects Cost

The projects that are smaller in size might be the sidewalk slab immediately adjacent to road making

set up and access very simple. The same size

project maybe at the rear of the house, down steps and around the pool. The contractor will need to consider the additional time it is going to take to reach the work site. Others may be in a confined area right next to a wood deck making it difficult to access the slab, requiring more time to complete the project.


How Weather Conditions Can Affect The Cost of Your Project

The climate where your project is located and time of year will have an impact on your cost.

If you live in the southern and southwestern temperate climates, contractors are able to work all year long and can defray their operating costs over more projects, therefore, reducing their price per pound of material compared to contractors in the northern climates where most can only work 9-10 months per year.

The temperature of the soil or substrate can also have an impact on your costs. As the soil temperature decreases in the northern regions, the yield of the polyurethane foam decreases, requiring contractors to use more material to accomplish the same work during the warmer months, therefore, needing to increase the cost per pound charged to the client.

So, there you have it – our costs for concrete lifting and leveling utilizing polyurethane foam.

When you include the pounds of foam required, the size of the project, additional voids, weather and access to the work site, the average cost of lifting and leveling your concrete is between $7.00 and $12.00 per pound of polyurethane foam. It’s important to remember that based on your contractor, location, and age of concrete, these prices will vary.
