Welcome to Concrete Raising Systems
For state-of-the-art concrete raising that uses eco-friendly polyurethane foam for concrete leveling in less time, with fewer holes, and won’t sink or settle again!
Mudjacking involves pumping a mix of dirt, water, and cement under the slab, and for a year or two, it looks fine. Then a dry Kansas City summer hits, that mix loses its moisture the same way the soil around it does, and the slab settles right back down. We don’t use this process to permanently repair concrete. What we do is inject a two-part polyurethane foam — it doesn’t take on water, doesn’t degrade sitting under the dirt, and when it’s cured a few hours later, you can park a car on it. The holes we drill are small, about the width of a pencil eraser, five-eighths of an inch. The foam goes in, and you can actually watch the slab lift in real time; it hits roughly 90% of its landing point within about fifteen seconds. Most driveways and sidewalks are a three-to-six-hour job, and you’re driving on it again the same afternoon.
Any concrete we lift that’s over ten years old is covered for two years. If it sinks more than three-eighths of an inch in that window, we come back and raise it again at no charge. We’ve been doing this since 2012, and we stand behind it because polyurethane foam holds up the way we say it will.
“I’m Ken Praiswater, and along with my business partner Jason Roland, we’ve been working in construction for a combined seventy-plus years. Jason started his own construction company back in 1988, so he’s seen just about every concrete problem you can imagine. I spent nearly four decades as a process engineer and builder before we started Concrete Raising Systems, and that engineering background is why I was drawn to polyurethane foam in the first place. The science behind it just makes sense, and more importantly, it works.”
We don’t find it necessary to dance around numbers, so here they are. Driveways typically run $1,100–$2,800 — most quotes are in that range, though a handful come in over $3,000 if the void underneath is bigger than usual. Sidewalks are usually $850–$1,500. Patios and front porches, $850–$1,600. Steps are usually $850–$1,500, depending on how many you’ve got. Garage floors and basement floors run higher, $1,500–$4,000, since they take more foam and more careful placement to get right. We don’t give quotes over the phone — we need to look at it — and there’s no deposit either way. You pay us once it’s done and you’ve seen the results.
A full driveway replacement runs three to five times the cost of polyurethane foam lifting, and you’re looking at close to a week with your car on the street instead of an afternoon in your own driveway. If the slab underneath is still solid, there’s no real reason to pay for new concrete when lifting the old driveway gets you the same result for a whole lot less.
We see this a lot: a homeowner had their driveway mudjacked five or ten years ago, and it’s sinking again. About 30 percent of the concrete repair work we do in Kansas City involves relifting slabs that were mudjacked once and didn’t hold. That’s not us knocking on the industry; it’s just physics. Dirt and water fill under a slab, and dirt and water are exactly what erodes and washes out from under a slab in the first place.
We raise and repair concrete. That’s it. We don’t waterproof basements, we don’t fix roofs, and we don’t redirect downspouts, though if one of those things is actually causing your concrete to sink, we’ll tell you straight and may be able to point you toward someone who can help. We’ve been in and around residential construction long enough to recognize when the real problem is somewhere other than the sunken concrete.
We work throughout the Kansas City metro, on both sides of the state line, including Kansas City, Kearney, Overland Park, Lee’s Summit, Blue Springs, Liberty, Parkville, Excelsior Springs, Olathe, and Independence. If you’re not sure whether you’re in our service area, just call and ask; we’d rather tell you plainly than waste your time.
How long has Concrete Raising Systems been in Kansas City?
Since 2012, and Jason and Ken have lived and worked in the metro for decades before that.
Is there a deposit?
No. Payment is due when the job’s done, not before.
Can you repair concrete in cold weather?
As long as the ground isn’t frozen, yes. We watch the forecast and schedule around it.
What if my driveway can’t be raised?
We’ll tell you. About 5 percent of the estimates we give end up needing replacement instead of lifting, and we’d rather say so upfront than take a job that won’t hold.
The fastest way to get an accurate quote is to send us a few photos of the area from a couple of angles, along with your name and phone number, through the contact form. If you’d rather talk it through first, call us at (816)419-8306. We can sometimes give you a ballpark over the phone, but most jobs really do need a quick on-site look before we can nail down the exact price, since every void is a little different.
If you want to see the kind of work we’re talking about before you call, we’ve got a before-and-after gallery of driveways, sidewalks, steps, and garage floors we’ve lifted around the metro. And if you’re trying to figure out whether your specific situation is a foam jacking job or something bigger, our driveway repair, sidewalk repair, patio and porch repair, garage floor repair, pool deck repair, basement floor repair, concrete step repair, and void filling pages each go into more detail on that particular kind of job, including what it typically costs and how long it takes.
We’re a small, Kansas City-owned business, and Jason and Ken are the ones who show up, quote the job, and do the work. If you want to know more about us before you call, the Meet the Owners page has our full background, or you can read through more questions and answers.
