An uneven concrete slab can cause more problems than most people expect. Whether it’s inside your home, in a basement, or part of an outdoor structure, a sinking slab can lead to cracks, uneven flooring, and safety concerns.
If your concrete slab is starting to settle, shift, or feel uneven underfoot, the issue is usually below the surface. When soil moves or washes away, it creates empty space that allows the slab to sink and lose support.
At Level Up Concrete Raising, we lift and level concrete slabs across the Denver Metro area by stabilizing what’s underneath—so you get a solid, long-lasting result without removing the slab.
Concrete slabs rely on stable soil underneath to stay level. When that support weakens, the slab begins to shift:
When the ground can no longer support the slab, it settles unevenly and creates visible and structural issues.
If you’re noticing any of these signs, your slab may need leveling:
These problems can continue to worsen if the underlying cause isn’t addressed.
Sometimes a sinking slab is part of a larger issue around the property. If you’re seeing uneven concrete in multiple areas, it may be caused by the same soil movement. Our team also works on driveway leveling, garage floor leveling, and walkway and sidewalk leveling. Addressing all affected areas can help prevent future problems and improve overall stability.

Scott SalzbergTrustindex verifies that the original source of the review is Google. Jeremy is incredible. He talked me through everything, truly educated me, and took the time to go above and beyond to ensure we could find solutions for secondary concerns. Their price was also extremely competitive. Recommend connecting with them before you start any lifting project Colton ParkerTrustindex verifies that the original source of the review is Google. Top notch team and price, wish I would have had my interior slab fixed years ago Storm BlaizeTrustindex verifies that the original source of the review is Google. This was one of the best experiences. Jeremy is honest and does not try to take you for an idiot or money grab. This referral is the only constant and I would never use anyone else!!!! Michael MTrustindex verifies that the original source of the review is Google. Jeremy and Eli went above and beyond to meet our needs and make our driveway exactly how we needed it. Their prices were by far the most reasonable for lifting (and we got quotes from 4 additional companies). Our needs were unusual as we have a very low car and steep driveway. They stayed to test if our car would scrape and ground portions of the concrete until it was perfect. We made the right choice 100%, a job well done. Keith PriceTrustindex verifies that the original source of the review is Google. Really impressed with Jeremy and the team! They did great work to restore my back patio to its original height. Very professional and informative to everything that was being done as well as were flexible and accommodating when it came to scheduling. Daryl SmithTrustindex verifies that the original source of the review is Google. Just had my entry step lifted about 3" by Jeremy and Eli and the process looks to have worked great. Thank you for fitting me in on short notice, I'm a builder and really appreciate the effort and the amount of time you saved me. I would recommend this company to anyone that does not want to demo and replace concrete flatwork. david bendinelliTrustindex verifies that the original source of the review is Google. Jeremy is one of the most honest businessmen that I have encountered in a very long time. He told me how to save money on my concrete job in areas that did NOT involve using his services. In other words, he willingly lost money by telling me the truth rather than to sell me his services that had a cheaper fix by doing it another way. I will never use a different company other than Level Up when I have a concrete issue.
We use a proven method to lift your slab and restore it to a safe, level position.
We drill small, clean holes into the slab to reach the empty space underneath where support has been lost.
High-density polyurethane foam is injected beneath the slab. It fills voids, stabilizes the soil, and lifts the concrete back into place with controlled precision.
We seal the holes and leave the area clean. In most cases, your slab is ready to use again shortly after the work is completed.
Leveling a concrete slab is a practical way to restore stability without the hassle of full replacement.
At Level Up Concrete Raising, we focus on doing the job right from start to finish. Whether we’re working at a home, a business, or a larger property, our goal is the same—deliver clean, professional results you can trust.
We show up on time, communicate clearly, and treat your property with care. Every project is handled with attention to detail, from the first drill hole to the final cleanup.

If your concrete slab is sinking, cracking, or uneven, we’re here to help.
We’ll take a look and give you a clear, honest recommendation.
Concrete slab leveling is a process that lifts and stabilizes a sunken slab by addressing the empty space underneath it. Instead of removing the concrete, we drill small access holes and inject material beneath the slab to fill voids and restore support. This allows the slab to be lifted back into position in a controlled way. You can learn more about how this works on our concrete leveling process page.
If you notice uneven floors, visible cracks, or sections of the slab that feel lower than others, it’s usually a sign the support underneath has weakened. Other signs include doors sticking, gaps forming along walls, or areas that feel unstable when walked on. These issues often start small but can become more noticeable over time as the slab continues to settle.
Yes, interior slabs such as basement floors, sunrooms, or enclosed spaces can often be lifted using the same process. We take extra care when working inside to keep the area clean and controlled. The goal is to restore a level surface without causing disruption to the surrounding space.
Leveling addresses the cause of the problem by restoring support underneath the slab. While it can help reduce stress that leads to cracking, it does not completely remove existing cracks. For sealing joints or cracks, we also offer concrete caulking as an additional service.
Most slab leveling projects can be completed in a few hours, depending on the size and condition of the area. Because the process is efficient and controlled, there is minimal downtime compared to full replacement. In most cases, the surface is ready to use shortly after the work is finished.
In many situations, leveling is a practical solution because it addresses the underlying issue without removing the slab. In many cases, it’s faster, less disruptive, and can save thousands compared to replacement—especially if the slab is still in good condition.
Replacement may still be needed in cases of severe damage, but concrete lifting is often the first option to consider when the structure is intact. Most slabs can be repaired in just a few hours and are ready to use shortly after.
You can compare options on our poly leveling vs mudjacking page.
Voids typically form when soil is washed away by water, settles over time, or was not properly compacted during installation. These empty spaces reduce support for the slab and allow it to sink. Our void filling service is designed to address these issues directly.
The process involves small drill holes that are patched once the work is complete. These areas are usually minimal and blend in with the surrounding surface. Most homeowners find the final result clean and far less noticeable than the original problem.
Yes, we prefer that you’re present so we can walk the area with you, explain what’s happening, and answer any questions. This helps ensure you fully understand the condition of the slab and the recommended solution.
We also work on driveways, garage floors, steps, and patios. If multiple areas are affected, we can evaluate everything together and recommend the best approach.
