If you've noticed that your driveways, patios, or sidewalks have sunken slabs, it's time to consider a reliable solution: foam concrete lifting. This innovative technique involves pumping a lightweight, yet strong, material beneath the slab to level it out. This article explores the benefits of foam concrete lifting and why it's a great option for homeowners.

The Strength of Polyurethane Foam

When it comes to lifting concrete slabs, contractors need a material that is strong enough for the job. Cured polyurethane lifting foam is stronger than crystalline bedrock. Lifting foams have density and compressive strength ratings, ensuring they can support the weight of your home's concrete slabs. Polyurethane outperforms traditional materials like clay and bedrock when it comes to load-bearing capacity. For example, Alchatek's AP Lift 430 and AP Lift 475 have compressive strengths of 50 psi and 100 psi, respectively, in a free-rise state. That's equivalent to 7,200 to 14,000 lbs per square foot of support. When injected into a confined space beneath your concrete slab, these foams increase their compressive strength even further.

Versatility in Concrete Leveling Applications

Contractors use polyurethane concrete lifting foams in various applications, from residential driveways to airport slabs supporting jumbo jets. These foams cure quickly, reaching 90% of their full strength within just 15 minutes. They also conform to the shape of the void more accurately than cement grout and don't shrink or sink over time. Alchatek's AP Lift foams come in a range of options, each with unique expansion and strength properties. For example, AP Fill 420 has the highest expansion, making it ideal for filling large voids, while AP Lift 475 has a lower expansion rate but significantly higher compressive strength. Your contractor will assess your specific needs and choose the most appropriate foam for your project.

Find a Foam Concrete Lifting Contractor
