Often times our clients will ask us to “level out” their concrete slabs due to the concrete not being even. There could be a couple different reasons for this: either their concert has sunk or it has an uneven surface. If it’s the first reason, and the concrete has sunk, concrete lifting is often the best way to address the issue. If it’s the second reason, and the concrete has an uneven surface, concrete grinding is a good solution. In this article we asked the Liftech team to tell us about their system to address sunken and unstabilized concrete. We recommend this team of professionals, who have been rated Colorado’s #1 polyurethane concrete raising and stabilization company, to all of our clients who need their concrete lifted because it’s non-invasive and works more effectively than other forms of concrete lifting.


The Colorado Front Range is made up of a large assortment of soil types. It ranges from very sandy soils to highly expansive clay soils with ever expanding and contracting Bentonite (Claystone). When wet, Sodium Bentonite expands, absorbing as much as several times its dry mass in water. The opposite happens when dried out.

Too often in construction, soil is not properly compacted, downspouts are not properly placed and landscaping drainage is poorly designed. When large quantities of water are directed towards any concrete slab, there is a possibility of soil erosion and or compaction. This leads to concrete settlement over time. Garage floors, basements, driveways, exterior walkways, porches and patios are the areas most frequently affected. Exterior concrete is generally poured at an angle away from any structure. This is an effort to keep water from pooling in a garage or to keep it from seeping down into a basement. When settlement occurs, and water is flowing in the wrong direction towards a house, more severe problems are likely to arise.




Our concrete repair plan includes the controlled lift of individual slabs of concrete. We achieve a precise result by applying expansive polymer foam just beneath the surface of the slab. This process eliminates the failing condition as well as seals and stabilizes all defective joints and sources of water penetration from further erosion. The variety of soils and substrates across the Front Range are often the root of the problem. Liftech’s concrete repair system treats the soils and addresses the water and erosion issues. The average life cycle of concrete is extended at a fraction of the cost of replacement.


  • LONG LASTING!   Polyurethane cures as a solid, impermeable structure which adheres to the concrete and is not susceptible to fracture or failure.
  • SOIL STABILIZATION!   Polyurethane is injected as a liquid and reacts within the loosely, uncompacted soils to solidify and stabilize those soils.
  • LESS INVASIVE!   Liftech uses controlled injections in penny-size holes to raise your concrete quickly and effectively.
  • LIGHTWEIGHT!   Polyurethane weighs about two pounds per cubic ft.
  • IT’S FAST!   Polyurethane cures within minutes, with your concrete ready to use again once we leave the job!
  • DEFEND AGAINST MOTHER NATURE SAFELY!   Our environmentally friendly solution creates a barrier to moisture, chemicals, insects, rodents and erosion.
