Top-Rated Concrete Injection Leveling Mudjackings Experts in Edmonds, WA

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!"

"It is a huge shock to realize that one's home is in such danger with a serious foundation issue that will be very costly. But I have to admit that from the very start Groundworks was awesomely professional and impressive. The evaluation process was ultra thorough. Then the actual workers were beyond amazing. The communicated fabulously with me daily to keep me in the loop. What impressed me the most was how very hard these men worked non-stop during the days, often staying longer than five o'clock to finish the day's job. They were careful with my home and property and cleaned up after themselves. It is quite a relief that in this day and age one can trust and witness such a great company with professionals that have such a phenomenal work ethic."
