How Do Polyurethane Foam Injections Work?

Polyurethane foam injections employ a two-part foam mix that expands beneath the concrete, lifts the slab, and fills gaps. Small, penny-sized holes are drilled into the concrete, and the foam is injected underneath. The rapid-setting foam cures in just 15 minutes, enabling accessibility to the treated concrete areas sooner than other repair methods.

Is Concrete Lifting Better Than Replacement?

Yes, concrete lifting is generally more affordable than full replacement. It involves raising the existing concrete to its original position, which saves on costs associated with demolition, disposal, and new concrete. PolyRenewal™ polyurethane foam is also waterproof and won't wash away like other materials, ensuring long-lasting results.

Can I Lift Concrete Myself?

Lifting concrete is a complicated process and it's important to remember that you need to think about all elements of the concrete, not just the initial lift. Relying on DIY solutions is almost always a problem. An expert will be able to help you understand your options and fix your sunken or cracking concrete properly.

How Long Does a Concrete Lifting Project Take?

A typical concrete lifting project usually takes just a few hours to complete, with the surface ready for use in just 15 minutes after treatment. Most residential projects can be finished in one day. The exact time can vary based on the size and condition of the area being serviced.

Concrete Lifting Solutions

What are the best solutions for concrete cracking and settling? As you may have expected, it depends substantially on where the problem is and what’s happening exactly. Concrete settling solutions may look different depending on the actual problem you’re trying to tackle.

The traditional method of repairing cracking and sinking concrete has been a process called mudjacking. This method involves drilling soda can-sized holes into the concrete, pumping a heavy concrete slurry mix under the slab until it hardens enough to lift the slab back up, and then waiting for the mix to cure. This process is invasive, time-consuming, and expensive.

However, a better alternative to concrete lifting is investing in polyurethane injections. The process is similar to mudjacking, but much more effective. Small, penny-sized holes are drilled into the concrete and polyurethane foam is injected underneath the slab. This foam is light but durable, waterproof, eco-friendly, and cures faster than the heavy concrete mix involved in mudjacking. Once the foam fills the void under the slab, the concrete will be effectively lifted back towards its original level position. You can even walk or drive on the newly repaired concrete within 15 minutes after the polyurethane foam has been installed!

Concrete Lifting FAQs

If you’re like many homeowners, your immediate thought may be that you should just repour the concrete. After all, a brand-new concrete slab will probably be stronger and more effective than trying to fix the existing concrete slab, right?

Fixing the slab with concrete lifting will be much more effective because it takes less time, isn’t as expensive, and doesn’t require as much hands-on effort to accomplish. If you can fix your concrete slab early, you don’t have to repour it.
