Trip Hazard Removal: Why Replace When You Can Lift?

Virtually all concrete cracks. Erosion, sinking, and shifting in the property over time cause cracks in the concrete or sinking of a slab. These changes form trip hazards or unsightly uneven concrete as the ground settles underneath the residential and/or commercial concrete work. Ryan Kartchner Concrete Construction is your solution to lifting, repairing or replacing any failed or sunken concrete in Utah.

Cracking may be found on the bottom of the concrete and not be visible until after it is lifted for repair. Slabs with a few cracks can be lifted by our professional “slab-jacker” at Kartchner Concrete in the Salt Lake City or Utah Valley area but severely cracked concrete may need to be replaced. Every effort is taken to prevent cracking during the concrete lifting by using the best concrete tools; however, RKCC cannot be held responsible for cracks since cracking may have already occurred underneath.

The technology used to lift concrete is centuries old and now has become available for residential concrete lifting in the Salt Lake area. Kartchner Concrete uses the ingenious process of slab-jacking that is also very cost friendly at 50 - 80% less than the cost of replacement! It is also a time saver. The entire process is usually completed in just a few hours, allowing the concrete to be back in use almost immediately. Be aware that any existing stains or cracks will still be there since the lifting process elevates the existing slab by pumping filler under it.

How does it work?

RK Concrete Cracked Concrete

• The lifting process consists of drilling a series of small holes in the slab where a special mix is pumped beneath the concrete slab.

• It is injected into the soil where it quickly integrating with the soil. There it expands into a lightweight, stable, durable material, which will increase the soil load bearing capacities.

• The lifting mix when pumped under pressure depresses the sub soil, stabilizing it by filling the void, raising the slab to the proper height.

• After the slab is lifted the small drill holes are then filled and patched with new cement.

Other factors which cause concrete to sink are water erosion or rodents undermining the base beneath the concrete in the Salt Lake Valley. These issues are part of regular home maintenance and need to be checked regularly by the home or property owner to prevent further problems. Make sure to take steps to check and insure all concrete cracks are sealed and trip hazards are repaired every spring after the wasatch front snowmelt.


Examples of where to look for slipping gaps:

• The sidewalk that is next to your foundation

• Around the garage slab and driveway

• By a sidewalk crossing a utility trench for a water, sewer or electric lines

These situations almost always involve excavation where dirt may have been simply dumped, not packed causing settling, slipping or shifting. Trip hazard removal is the responsibility of every conscientious property owner.

Note: Rodents and squirrels dig holes that undermine concrete endurance in the western states. When expecting all your concrete, look for small holes or signs of digging beside your exterior concrete work as an indication of rodent activity. Rodents must not be allowed to tunnel in your yard causing expensive concrete repairs. You may need to call a professional exterminator if you cannot stop them from digging.
