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!"

Our top priority is providing high-quality home repair solutions and personalized service across the Seattle area. With fully trained technicians, industry-leading products, and nationally backed warranties, Groundworks is here to restore your foundation.
"Had Groundworks install a drainage system and sump pump in our home’s crawl space. Anthony and his crew, Jordon, Uriel, and James were Outstanding. It was a three day job. They were on time every day and worked their tails off each day. It was a muddy job in cramped quarters. They never complained. Anthony kept me updated on the progress they made each day. Anthony shared pictures of the job as it progressed. They cleaned up the job site each day. Anthony went over all the details at the completion of the job and answered all of my questions. The whole process was Great. From the initial inspection done by Kristy to the office staff and the installation. The communication was also Great. I highly recommend Groundworks for a complete and thorough job."

"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."
