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!"

"Groundworks were contracted to encapsulate the crawl space, with a dehumidifier, intellijacks & sump pump. The inspector showed us pictures & videos of what the work would look like on completion, & explained how each solution would be installed. They tried to charge me more for vent covers until I showed them the contract covering this part. The foreman told me there was a reset button for the sump pump to be installed on an exterior wall, but they did not install it, instead said they would put in a service order. I haven’t heard anything about this issue yet. When they installed the moister barrier, they excluded the cement pads I was told it cost extra to have them covered. When I signed the contract, I was never told there would be extra charges for vent covers or cement pads to be covered. The contract I signed covered a complete encapsulation, but this is not what I got. This is a bait & switch. I would not recommend Groundworks."

"Rafael and his crew were amazing to work with. The initial visiting for a quote was free and very informative. He was quick to understand my sketches for a totally different deck design, asked really helpful questions, and gave clear recommendations. They were able to start promptly. All of the crew members were very professional in their communication and planning and updates. They were highly skilled and did excellent quality work. I am so happy with my new deck! When work was done, they honored their quoted price. For my project they did not ask for any payment upfront, just payment in full upon completion to my satisfaction. They do take other payment methods but prefer cash so I suggest you ask about your payment options upfront. For the whole process, this company was great to work with. The craftsman of the finished work was excellent quality. I recommend them to everyone."

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.
