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.
"During periodic heavy rains we sprung a leak in our basement wall. I called Perma-Dry because both Angie's List and a plumber recommended the company, and I do not know the first thing about waterproofing a home. I scheduled a date and time for a salesperson to inspect the basement and provide me with an estimate. Mark was friendly and professional, and in his estimate he wrote that a sump pump may be required. What he did not elaborate in his inspection is the sump pump requiring GFCI, a term he wrote on the estimate but did not explain during the inspection. I am not an electrician and I have already established I do not know the first thing about waterproofing. What I came to learn during the scheduled work is that a) the crew confirmed a sump pump would be required, and that b) GFCI means a dedicated electrical line for the sump pump. We have a warbox-style home from 1942 and there is only so much we can do to the existing structure. Our washer and dryer are in the basement and now our washer will share an outlet with the sump pump, and I'm going to hope for the best. The work crew is nice but they do love to get animated about the work they are performing. I'm fortunate to work from home today and participate in phone conferences on mute so my colleagues didn't have to hear "BULLSH_T" being exclaimed loudly. Bonus use of the n-word when they returned from lunch. What would have been immensely helpful in the original inspection is Mark explaining, "We should check to see if you have the necessary electrical setup for the sump pump, otherwise you will need to hire an electrician and that could run $600." When I had Mark in our basement I was trying to think of every possible question to ask him before agreeing to an estimate and scheduling a service appointment. Where I failed in my exercise is that I didn't know the questions to ask during the inspection, and now the crew is installing a sump pump that I cannot reject because it's the only way I can achieve the goal of waterproofing the basement. A quick email to the company did not feign a reply from anyone other than a follow-up call with Mark who, professionally, explained he did his part to address his due diligence in the estimate to cover liability for the company. I explained to Mark that since I do not know the first thing about waterproofing (established) I did not know all the right questions to ask, and I am now having to authorize $825 for a sump pump in hopes that I don't need to hire additional servicemen to confirm the work is complete. The conversation was moot aside from him understanding my frustration. If you are a homeowner like me that is unfamiliar with waterproofing and home electrical, be sure to ask the salesperson if your home is properly set up to accept a required sump pump, or if you will need to schedule an electrician to wire your home ahead of the waterproofing work. If you are a homeowner like me that is unfamiliar with waterproofing, make sure you ask your salesperson for visual examples of the sump pump so you can adjust any configuration of storage solutions you had in your basement that must now be reconfigured due to the size of the pump and the space it will occupy. Because you don't know if there is more than one option for the sump pump (there isn't on the day of work). You can, however, hope the crew will not cut into existing pipes and do their best to work with the plumbing. FYI: the warranty offered for the drain system DOES NOT apply connection to an existing non-company installed drain line. Meaning that the sump pump required for completion of work is not covered by the drain system warranty when the crew connect it to your existing plumbing. The crew finished ahead of schedule and I was shown the results. The poured concrete will take 3-4 days to thoroughly dry; we can move our washer back at that time and reinstall all the hoses. I wish I would have known in advance how long it would take for the concrete to be dry but I guess that, too, was a question I was supposed to know to ask. The sump pump is already plugged into the wall socket but we'll need to rely on the battery powering the sump pump control box because we don't have another outlet to spare for the second plug. If we didn't have that outlet at the ready, I would be back on Angie's List looking for an electrician and I wish Mark would have had a checklist at the ready to make sure all of this was addressed before the crew tore open the basement floor with a jackhammer and then concluded a sump pump was necessary. The purpose of Angie's List is to reduce the risk of "Buyer Beware" for consumers, yet here is a business model that penalizes consumers because they don't know the questions to ask. I hope my experience will save you from a similar situation so you're not left frustrated with a company's reply being "I understand" on repeat."
"I needed a garden path from my house to my art studio, and I wanted it to match the concrete path already going from my house to the garage. Not a big job, but American Concrete Construction was willing to take it on. Their main guy, Sinisia Moli, came right out one day to evaluate the job, then returned the next day to survey, dig out the path, frame it, and put in rebar. Cement was poured the following day. And now I have my garden path. Which, incidentally, matches the other, much older path perfectly. ... Sinisia Moli of American Concrete Construction is a man of experience, good aesthetics, and common sense. He is also friendly, upbeat, and generally a pleasure to have around. Best of all, unlike so many of his colleagues who work in various construction trades, Moli talks to women. He doesn’t insist on talking to your husband. ... I am definitely keeping American Concrete Construction in mind for future projects."

Concrete Mudjacking questions, answered by experts
The timeframe is generally a few hours, allowing for immediate use post-hydration, ensuring minimal disruption to surrounding activities.
Mudjacking typically takes 24 to 72 hours (one to three days) to dry and cure completely before you can resume normal use. The exact time can vary depending on the size of the project. Because the slurry mixture contains cement, it must fully harden to ensure that added weight from walking, furniture, or vehicles won't shift the concrete slab. A professional contractor can advise you on when the surface is safe to use. For comparison, if you use polyjacking instead, the polyurethane foam can dry in just a few minutes, but it's best to wait about an hour before use.
A slurry of cement, sand, and water is injected beneath the concrete to lift and stabilize it.
The average cost for mudjacking is around $1,200, though prices can range from $300 to $3,400. On a per-square-foot basis, you can expect to pay between $3 and $8, with an average of about $5 per square foot. The final cost depends on several factors, including the square footage of the concrete, the type of slab, its accessibility, whether it is load-bearing, and the type of material used to lift it. Generally, lifting a driveway, small patio, or sidewalk is less expensive than lifting a slab foundation or garage floor.
There is no real alternative to underpinning, although mudjacking and polyjacking are other repair methods that can add support from underneath your foundation. Rather than placing supportive piers under your structure, these involve pumping a material under your slab to lift a sunken section back into its original position. Polyjacking, in particular, is sometimes a suitable solution for stabilization issues under slab foundations, but underpinning is often accepted as the best and most permanent solution.
