Sunken Patio Repair in Springfield, OR
If your patio is sinking, cracking, or uneven, you’re not alone. Many homeowners in Springfield, OR and the greater Lane County area deal with shifting soils that leave concrete slabs unsupported. Over time, this creates dangerous, unsightly surfaces that can get worse if left untreated.
The good news is you don’t have to replace your patio. With professional concrete patio leveling, we can restore your slab quickly and cost-effectively.
What Causes a Sunken Concrete Patio?
Most sunken patios are caused by voids forming beneath the slab. These empty spaces develop when soil compacts, washes away due to water, or becomes unstable from poor drainage.
As the support beneath your concrete disappears, the slab begins to sink, crack, and become uneven.
Concrete Patio Leveling with PolyLevel
We fix sinking concrete using PolyLevel®, an advanced foam injection system designed to address the root cause of the problem.
Small holes are drilled into the slab, and high-density foam is injected underneath. As the foam expands, it fills voids, stabilizes the soil, and gently lifts the concrete back into its original position.
PolyLevel is lightweight, waterproof, and cures quickly, meaning your patio is often ready to use the same day. This makes it a fast, non-invasive alternative to full concrete replacement.

HOMEOWNER QUESTIONS
How does the warranty work?
For concrete slabs raised with TerraFirma’s PolyLevel®, we guarantee that the area where the slab of concrete was lifted will not settle more than ¼ inch for a period of 5 years from the date of installation. If it does, we will provide the labor and materials to re-level the area at no additional charge.
What is better: mudjacking or polyurethane?
A Polyurethane solution is not as messy or disruptive as other foundation-lifting techniques like mudjacking. Our PolyLevel solution is lightweight (without compromising strength), offers faster installation and cure time, making it the best option available.
What kind of foam is used to lift concrete?
High-density polyurethane foam is the expert’s choice for concrete lift. Our PolyLevel solution uses a high-density polyurethane foam to fill voids and stabilize sinking concrete slabs. The expanding properties of the two-part urethane formula allows for the lifting of the slab.
Can you repair cracked concrete after going through concrete leveling?
Yes. In fact, we recommend that our TerraFirma Concrete Leveling customers seal the cracks and joints of their newly lifted concrete with our NexusPro solution, as it will help protect their concrete for many years to come.
My concrete seems to have settled over the winter. What should I do?
Your concrete most likely didn’t settle, but instead the adjacent concrete slabs heaved upwards, due to the frozen dirt below. There is nothing that can be done, but wait for the ground to thaw and the concrete to return to its original position. If the concrete doesn’t return to its normal position in the spring, you may want to have one of our experts take a look to determine if a permanent solution is necessary.
Patio Sunken Concrete Fix + Crack Repair
Lifting your patio is only part of the solution. Cracks and joints must also be sealed to prevent water from getting underneath the slab again.
We use NexusPro® joint sealant to seal cracks and joints. This flexible material is designed to withstand temperature changes and long-term exposure, helping prevent future soil erosion and concrete movement.
Protect Your Concrete with SealantPro
To complete the repair, we apply SealantPro®, a professional-grade concrete sealer.
SealantPro reduces water absorption and helps protect your patio from long-term damage, including cracking, surface deterioration, and freeze-thaw cycles. This added protection helps extend the life of your concrete and keeps it looking better for longer.
Is It Cheaper to Repair or Replace Concrete?
In most cases, repairing your patio is significantly more affordable than replacing it.
Concrete patio leveling is faster, less disruptive, and targets the underlying issue causing the damage. Replacement, on the other hand, involves demolition and repouring—and often does not address the soil problems that caused the sinking in the first place.
For many homeowners in Springfield, OR, leveling is the smarter long-term investment.
