Driveway Failure


Driveways are high moisture areas making them highly susceptible to erosion.

Driveway Repaired


Polyurethane raises and stabilizes the areas sealing out moisture which prevents further erosion.

Failed Garage Floor

When garage floors settle they no longer drain properly causing moisture to erode the soil along the floors perimeter ultimately causing failure.

Trip Hazards


Soil erosion can cause concrete to settle at the control joints creating dangerous trip hazards.

You May Proceed

Polyurethane is injected to raise and stabilize uneven concrete to quickly and effectively eliminate trip hazards.

our process

A solid substrate and well compacted soils are fundamental to providing a solid foundation upon which concrete structures perform. Over time, Mother Nature takes its toll, especially here in Denver and across the Front Range. Ground water, erosion and soil decomposition can break down the structural foundation. This is the primary source of failure for roads, bridges, sidewalks, driveways, walkways, and other concrete platforms. Liftech uses an advanced process of injecting a two part polyurethane which reacts to form a solid structure in and around voids and areas of wet or loosely compacted soils to strengthen and re-stabilize the substrate and provide a solid, water tight environment.

Concrete Problem

The Problem

Soils are susceptible to the forces of nature, causing them to contract, expand and ultimately fail. Without proper support the overlying concrete sinks, creating not only an aesthetically unappealing environment, but also a hazardous and unstable structure. Left unattended this may lead to larger, more expensive problems. Read More

Concrete Solution

The Solution

Each failure is unique and requires careful planning by a skilled technician to design and implement a repair that will withstand the test of time. Liftech uses an advanced process to inject an expandable polymer under the concrete to raise it, and at the same time, stabilize the soil to prevent recurring failure. Read More

The final result

The Result

The process repairs and eliminates the failing condition within minutes and is ready to return to service immediately. Drainage and other issues affecting adjacent structures are remedied. The life of the concrete is extended for many more years. Read More

We use an advanced process of injecting a light weight, expanding polyurethane foam to raise, level, and stabilize at a fraction of the cost of replacement. Unlike mudjacking, Liftech is also a minimally invasive and permanent solution to repairing flatwork of any kind.

Some Testimonials:

"Half the price of replacing and looks great!"

"Not only will we give you a referral, but we would like you to come back for more work at your convenience! We did not do the driveway bump at the bottom and would like you to repair that when you can. Anyone who would like a referral can even come and look at our sidewalk repair if they would like... it is so much better and I never fear people tripping again. It has been one year and we are so pleased. You came promptly and Liftech was so much better than mudjacking... we have seen mudjacking repairs all over Grant Ranch and they are dropping dramatically. It was one half the price of replacing and looks great! You even filled in under our front porch and it looks so much better. You cleaned up after yourself nicely and I've hardly ever seen someone work so hard! Liftech was prompt, clean, courteous and thorough. Highly recommended. Five stars. Call when you are in the area and you are hired again!" – Chris P.

"Perfect solution to the problem"

cross section of driveway"We discovered that the sidewalk leading up to our front porch had settled several inches from the porch and had become unsightly and potentially dangerous. After talking with you at the Denver Home and Garden Show we decided that your solution to our problem made the most sense. Since the sidewalk itself was completely intact it seemed a shame and an unnecessary expense to break it up and totally re pour it. Your Liftech process of essentially "floating" 20 feet of the sidewalk back into place turned out to be the perfect solution to the problem.

The material used to raise the sidewalk hardened quickly yet kept the sidewalk in place and as level as it had been prior to settling. After you caulked the seam between the porch and the sidewalk you would never have known that they had been separated. I was amazed at how quickly you completed the repair and at a very reasonable cost to us. Well below the hundreds, if not thousands, of dollars it would have taken to totally break up and re pour the sidewalk. Plus your process allowed us to use the sidewalk almost instantly after the application while new replacing it would have had to cure for days. With your 5 to 10 minute cleanup of the area the totally completed job took less than an afternoon. Thank you for a great job well done." - Eva and Spence K.

"We made the right choice to go with Liftech"

"We are very pleased with our experience with Liftech. We were happy with the price, and we really felt after researching the matter that the poly foam was a much better solution for concrete lifting than traditional mudjacking. A big reason we used Liftech was their professionalism. Several of the mudjackers we contacted simply never responded (as if they just didn't want the business), and the others showed up late, became irritated when I asked questions, or were deceptive. Liftech was the complete opposite: always on time and professional, very willing to answer my questions, and honest/ethical the entire time. The end result looks great, and the front walkway, which used to collect water and freeze in the winter, creating a dangerously slippery ice patch, now drains correctly. I know we made the right choice to go with Liftech." – David D.

If your concrete has created a hazardous or unappealing condition and you want it fixed for good, Liftech is the solution for you. Our application is used across the residential, commercial and municipal industries from sidewalks and driveways to roads and bridges.
