Concrete settling and unevenness can be a major headache for property owners. We understand the frustration and potential safety hazards of sunken or cracked concrete surfaces. That’s where polyurethane concrete lifting, also known as concrete raising foam, comes in, offering a modern solution to this age-old problem. This concrete leveling with foam technique has gained popularity in recent years due to its effectiveness and efficiency in concrete repair.
We’ll walk you through the process of lifting concrete with foam. We’ll cover the basics of this method, including how expanding polyurethane foam, a type of polyurethane foam for concrete, works to raise concrete. You’ll learn about the preparation steps, the actual foam jacking procedure, and the aftercare needed to maintain your newly leveled concrete. By the end, you’ll have a solid understanding of this innovative concrete foam jacking technique and be better equipped to tackle your own concrete repair projects or find polyjacking near me.
Understanding Polyurethane Concrete Lifting
Polyurethane concrete lifting, also known as polyurethane slab jacking, is a modern, cost-effective solution for fixing sunken concrete. This innovative technique involves injecting high-density polyurethane foam for concrete beneath the concrete slab. As the foam to lift concrete expands through a chemical reaction, it lifts the concrete back to its original level. This foam injection concrete leveling method has several advantages over traditional approaches like mudjacking.
It’s less invasive, more precise, and offers a longer-lasting solution. The concrete lifting foam is lightweight, weighing only 2-4 pounds per cubic foot, which puts less stress on unstable soil. It’s also waterproof and eco-friendly, made from renewable and recycled materials, addressing environmental concerns. Polyurethane concrete leveling can be used for various applications, including leveling sidewalks, driveways, and patios, making it a versatile choice for both residential and commercial projects.
Preparing for the Lifting Process
Before starting polyurethane concrete lifting, it’s crucial to assess the site thoroughly. We begin by inspecting the area for signs of settling, such as visible cracks or gaps between the concrete and the building. This helps us determine the extent of the damage and whether foam to raise concrete is the best solution. Next, we clear the area of any obstacles to ensure safe access for our concrete raising equipment.
We also clean the site, allowing for precise drilling of the drill holes. Safety is our top priority, so we follow strict protocols, including wearing proper protective gear. We cordon off the work area to prevent accidental interference during the concrete raising process. By taking these preparatory steps, we set the stage for a successful concrete lifting project.
Step-by-Step Polyurethane Concrete Lifting
We start by drilling small holes, about the size of a dime, into the sunken concrete slabs. These holes are strategically placed to allow for optimal coverage. Next, we insert injection ports into the holes. Using specialized concrete lifting injection equipment, we inject the two-part polyurethane foam beneath the slab.
As the foam expands, it fills voids and lifts the concrete, providing void filling and concrete slab support. We carefully monitor the process, adjusting the injection rate and volume as needed to ensure even lifting and prevent over-raising, thanks to the precise lifting control offered by polyurethane concrete raising. The foam hardens quickly, usually within 15 minutes, providing immediate support and impressive compressive strength.
Once the desired level is achieved, we remove the injection ports and patch the holes with grout, leaving minimal mess. The result is a leveled, stable concrete surface that’s ready for use almost immediately. This efficient polyfoam concrete lifting process minimizes disruption and provides long-lasting results.
Aftercare and Maintenance
Proper care is crucial for long-term durability after polyurethane concrete lifting. We recommend regular inspections to catch any early signs of settled concrete or damage. Also, keep an eye on drainage around the lifted area to prevent water pooling, which can erode the soil beneath.
Apply a high-quality concrete sealer to protect the surface from moisture and potential damage. Clean the concrete regularly using gentle detergents and soft brushes to avoid abrasive damage. Maintain proper landscaping around the concrete to prevent root damage.
Use plastic or rubber-edged shovels for winter maintenance and avoid harsh de-icing chemicals. Annual professional inspections can help identify and address minor issues before they become major problems, ensuring the longevity of your polyurethane concrete raising investment.

FAQs
What is the process for elevating concrete using polyurethane?
Elevating concrete with polyurethane involves the careful foam injection of lifting foam in incremental amounts. This foam expands rapidly within 10-15 seconds, allowing precise control over the lifting process to avoid over-elevation. It is recommended to use an air-purged gun for injecting the foam beneath the slab.
How durable is polyurethane concrete lifting?
Polyurethane concrete raising offers a durable solution, with the effects potentially lasting over 20 years. This method provides a long-term remedy for sinking concrete.
Which method is considered the best for lifting concrete?
The most effective and simplest method for lifting concrete with foam is the injection of lightweight polyurethane foam, also known as polyjacking. This technique involves injecting the foam through small holes directly under the affected concrete slabs.
What is the cost range for polyurethane concrete lifting? How much does polyurethane concrete lifting cost?
The cost typically ranges from USD 5.00 to USD 25.00 per square foot. For a precise cost estimate specific to your project, it is advisable to request a free quote from a professional concrete raising company.
