Concrete slabs can sink over time because underlying soils erode or otherwise degrades. Uneven concrete steps, walkways and ramps cause trip hazards and are a serious safety issue. Our polyurethane foam is hydro-insensitive, meaning it works well in a wet environment. It is also hydrophobic, meaning it displaces the water which prevents further erosion. Our process is a cost-effective, minimally invasive, quick yet precise solution.
Our unique and effective process for slab-lifting employs an array of special high density expanding polymers which are injected through small 5/8″ holes drilled directly through the concrete slab. As the resin mixture expands, voids are filled and a controlled mold pressure is exerted on a limited (8 to 10 foot diameter) area.
The aggressive nature of our resins not only effectively fill voids under concrete slabs but also effectively under-seal the slabs and helps in preventing water infiltration. Once the voids are filled a controlled lift will ensue to align differentially settled slabs or lift settled concrete panels.
Typically, the only limiting factor to lifting settled concrete slabs is if the slab is a structural slab. (Lifting structural slabs has been effected but in most cases the concrete starts to break-up due to the friction on the piles of the structural slab). Our hydro-insensitive polymer resins work equally effectively in lifting concrete panels in wet substrates. Any trapped water is forced out of the voids and replaced with a stable and long-lasting base material. The composite material quickly cures so as soon as the work zone is cleared away, the work area is immediately ready for normal traffic use.
Mitigating trip hazards is one of the most valuable uses of polyurethane foam Injection. Tilted or sunken concrete can occur almost anywhere, and when it does, trip hazards are often created. Our Process involves injecting a geotechnical polyurethane foam through 5/8″ holes drilled through the concrete slab. Once injected beneath the slab, the polyurethane quickly fills all available voids underneath the slab. It then compacts the compromised soil. Once the soil is adequately compacted, the polyurethane will begin to lift the slab until it is level once again. Lifting and leveling concrete with polyurethane foam is a cost effective, convenient and permanent solution.
Sidewalk panels on your property often settle differentially over time. This can create dangerous trip hazards for you and your family. Poly-Mor’s polyurethane foam injection process will lift and realign those panels to eliminate those trip hazards and provide a safe walking path while in your yard.
Having a sunken or tilted garage slab can create serious drainage issues and even pooling water in your garage. Large cracks and crevices in your garage floor will allow water and salt to penetrate your slab and cause even more damage to the structure and erosion underneath. Poly-Mor Canada has been leveling out uneven garage floors for the past 25 years. Our unique and effective process for slab lifting employs an array of special high density expanding polymers which are injected through small 5/8″ holes drilled directly through the concrete slab. As the resin mixture expands, voids are filled and a controlled mold pressure is exerted on a limited (8 to 10 foot diameter) area. Once the voids are filled, a controlled lift will precisely bring your garage floor back to level.
Summer is always closer than it appears. Planning on enjoying that backyard pool, do you have concrete slabs that have settled over the winter, are the slabs pulling away from the coping which are causing trip hazards? Poly-Mor Canada Inc. is pleased to provide excellent customer service and amazing solutions to concrete settlement and weak soil issues
Uneven concrete joints in a commercial floor are a serious problem. Not only can they create trip hazards, but forklifts repeatedly hitting the higher edge of the joint is a major cause of work-related injury in warehouse settings. Poly-Mor Canada has been removing the bumps in commercial floors for 25 years! Our process of injecting high density expanding polymers is ideal for stabilizing settled concrete slabs and precise concrete joint matching to create a level transition. The process is highly effective as the polyurethane fills voids underneath the slab, densifies and compacts the weak soil, and the smoothing out those forklift rides.

Sunken and uneven concrete in commercial spaces is not only unsightly, it is often the root cause of many safety hazards. Pooling water can form in low areas, creating a frozen slip hazard as well as soaking the feet of people working and visiting the space. Uneven concrete poses a risk to floor-mounted shelving and storage units. It can also damage underlying infrastructure such as pipes and drains. In some cases, concrete can become so uneven that it may prevent the proper close and/or opening of doorways, creating a security and safety issue.
Poly-Mor Canada has been helping commercial clients over the past 25 years to keep their commercial spaces safe and on the level.
Having a level substrate in an ice rink is critically important. Settlement can create a number of challenges including mis-alignment of the boards and preventing the gates from opening and closing. Further, an unevenly-settled ice slab places additional stress on the ice making equipment and the quality of ice that is needed to be made in a timely fashion.
With 25 years of experience, Poly-Mor has the expertise and equipment necessary to accurately stabilize, void-fill and level an ice rink floor according to the precise specifications of the client.
This technology is applicable in the industrial, commercial, residential, public works and institutional markets where the lifting of differentially settled slabs or settled concrete slabs is required. Some examples of specific slab-lifting uses include:
In the event the treatment area has in-slab heating or other mechanical/electrical services within or under the slab, Poly-Mor can detect these services using its infra-red and/or GPR technology to ensure the drilling procedure does not damage these services. In the event pipes/ducts etc. are broken or improperly sealed at the joints, the expanding resin when injected in their proximity they will be “filled” and “plugged” because of the aggressive nature of our expanding resin systems.

Not only are rocking / sunken slabs damaging to your equipment, they present a serious risk to the safety of personnel. Over the past 25 years, Poly-Mor Canada has fixed sunken concrete in dozens of industrial settings, from airport runways in Alaska to nickel mines in Labrador. Trust Poly-Mor’s 25 years of experience to keep your industrial facility’s floors safe and on the level.
Maintaining the integrity of a bridge is a crucial component for the safety of vehicles and drivers. There are many challenges with upkeeping bridges depending on weather, location, and traffic density. Poly-Mor offers multiple solutions depending on the conditions or needs of each structure.
Any slab-on-grade structure constructed for industrial, commercial, residential, Public Works or institutional purposes!
The Challenge: One of the four rinks in this public ice arena had settled over its 20,000sq. ft. surface from–1-5inches.The settlement created a number of challenges including mis-alignment of the boards and gates as noted in the adjacent picture and inability to open and close the gates. Further, the settled ice slab placed additional stress on the ice making equipment and the quality of ice that could be made in a timely fashion.
The Solution: Firstly, the in-slab brine lines were drained and air tested to ensure no breaks or leaks occurred due to the slab settlement. The brine lines were filled with warm water and using infra-red technology, the brine lines were located and identified. Some 600–5/8 inch holes were drilled through the slab in between the brine lines. Poly-Mor high density hydro-insensitive expanding polymer resin was injected beneath the slab to effect the necessary lift in accordance with the elevation profiles provided by the client. Laser levels and Compu-levels were used to ensure accurate lifting of the concrete slab.
The Success !
In five days, the entire 20,000 sq. ft. Rink slab was lifted and aligned within one-quarter inch tolerance of the specifications provided. During this same period of time, the exterior walks were lifted and aligned removing dangerous trips and excessive slope. The common area floors at the rink entrance were also lifted with resultant re-alignment of partitioning walls and doors.
BRIDGE APPROACH LIFT
The Issue: The 10” concrete approach panels on both sides of a bridge located on a rural road some 50 km. N W of Red Deer, Alberta had settled up to 3” resulting in vehicles launching themselves onto the bridge deck. The incline was considered too steep and posed a hazard to vehicles travelling a higher speeds.
The Solution: An array of 5/8” holes were drilled through the concrete pavement and a high density hydro-insensitive expanding polymer resin was injected beneath the 35’ x 9’ concrete approach panels on both ends of the bridge. Once injected, the resins expand 20 times their liquid volume, filled the large voided areas and then slowly and accurately lifted the approach slabs back to their appropriate elevation relieving the excess slope on the approach panels. During the work process traffic was not impacted and as soon as the crew completed their work, traffic immediately returned to normal as the polymer resin system used sets up and cures very quickly.
