Northwest Poly Services specializes in lifting concrete. We’re here to help our fellow residential, commercial, and municipal neighbors repair their sunken concrete slabs, walkways, and stairs. Our Pacific Northwest climate makes large demands on our soil, often causing our sidewalks, garage floors, and concrete slabs to settle and become uneven. This can lead to trip hazards, or worse, more major problems like drainage and soil erosion. Let us help! By drilling a small hole through your sinking concrete and injecting our poly foam solution, we can lift those problem areas level again. We serve Snohomish, Skagit, Whatcom, Island, and San Juan Counties. Give us a call or send us an email for a Free Estimate. Our service comes with a 25 Year Transferable Warranty and proceeds from every job go right back to the communities we live and work in.
"They raised a sunken cement sidewalk. They were punctual, efficient, explained things well, friendly, cleaned up, and did great work! Beautiful! I highly recommend them!"

"On one side of my house is an area where I keep my trash cans and on the other side is a kitchen garden. They used to have gravel that had over the years become clogged with dirt and constantly needed weeding. Now they are both paved and are not only low maintenance, but look GORGEOUS all of the time. Rios also fixed the lip of my driveway that had developed a precipitous drop-off to the main road, scraping the undercarriages of the unwary. It looks better than ever and can be adjusted if the edge of the driveway continues to be pushed up by roots underneath."

Mudjacking and foam jacking differ significantly in both materials and methods. Mudjacking uses a cement-based slurry to fill voids beneath a slab, while foam jacking uses expanding polyurethane foam delivered under high pressure to achieve superior structural support. This material distinction enhances load-bearing strength and overall stability in your repair.
Mudjacking takes between one and three days to dry completely. During this time, it's important to avoid putting weight on the slab until it's fully cured. The drying time depends on the project size and environmental conditions. In contrast, polyurethane foam used in foam jacking can cure in as little as one hour.
No, mudjacking is not a permanent fix for sinking concrete. While it effectively lifts the slab and can last five to 10 years, it doesn't address underlying soil issues that may cause future sinking. For a more permanent solution, you might consider foam jacking or complete slab replacement, which can address deeper structural problems.
