KALAMA HOMEOWNER REMOVES A TRIPPING HAZARD
A homeowner in Kalama, Washington noticed that the sidewalk in front of her residence had started cracking and settling. The uneven concrete created a noticeable tripping hazard for the homeowner, her neighbors, and guests.
Looking for a long-term solution, she contacted TerraFirma for a professional inspection and recommendations for sidewalk repair in Kalama, WA.
THE PROBLEM
Cracking and settlement had left sections of the sidewalk uneven. Beyond affecting the appearance of the walkway, the raised edges created a safety concern for anyone walking across the area.
A TerraFirma System Design Specialist inspected the concrete and recommended a repair approach using PolyLevel® rather than leaving the sidewalk to continue settling.

THE TERRAFIRMA SOLUTION
TerraFirma recommended PolyLevel® polyurethane foam to lift and stabilize the settled concrete.
After leveling the sidewalk, NexusPro® was used to seal cracks and joints. Together, the two products addressed the uneven slab and the openings at the concrete surface.
The TerraFirma crew completed the sidewalk repair in one day, leaving the walkway more even and addressing the tripping hazard that prompted the homeowner to call.
WHY USE POLYLEVEL®?
PolyLevel® is designed to lift and stabilize settled concrete by injecting polyurethane material beneath the slab. The material fills voids below the concrete and allows the slab to be carefully raised toward a more even position.
For suitable sidewalks, driveways, patios, and other concrete surfaces, this type of repair can address settlement without immediately removing and replacing the entire slab.
CONCRETE REPAIR
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.
