The concrete slabs around your Columbia property aren’t the only structures capable of settling. If you have any concrete steps around your home, then they can also settle. Just like a regular slab, concrete steps settle because the layer of soil that is meant to support them erodes and becomes uneven. Even if your steps have sunken a few inches into the ground, they can be repaired using polyurethane foam injections.
Contracts drill holes in the steps and use a handheld device to inject polyurethane foam. The foam expands and fills the void until there is enough to lift the steps back to their original position. The holes are covered back up, and the polyurethane foam is left to cure for 15 to 30 minutes. Concrete steps that have been cracked can still be repaired with this method, but only if the cracks are minimal. If the steps are significantly broken, then there is a chance you might have to replace them instead.
The only way to properly repair concrete steps is to use polyurethane foam injections. Many DIY blogs will recommend various methods that have nothing to do with solving the actual problem at hand, which is to give the steps a new support since the soil has eroded. Evening out the steps using cement, digging a hole and placing a rock under the steps, and other strange methods will only weaken the structure further and cause the steps to break completely. Without proper support, the steps will remain structurally unsound, which is extremely dangerous for all of those who use the steps. To avoid injuries, you must hire professionals for a proper concrete lifting job.
