What Is Concrete Leveling?
Also known as “slab jacking”, concrete leveling is the action of bringing concrete that is sagging or sunken back to a level surface again. Most of the time, you can call in the experts to drill a series of holes into sunken concrete. However, concrete leveling involves a lot of liquid (which resembles the thickness of mud) foam being pumped under the concrete through the drilled holes. The pressure of the mud being injected pushes up the concrete and remains in place to offer support once it’s up again. This then discourages the concrete sinking again later. Denver concrete leveling & raising results in a smooth concrete finish where the mud was pumped through the holes.
In some cases, concrete is poured onto the top of a sand base that has been compacted and often, it’s not compacted and settled enough before the concrete is poured out. This then leads to sand eroding over time. This then causes the sag in the concrete that we mentioned earlier. When this occurs, the concrete sits far lower than it was intended to originally, which then leads to water collection, broken and cracked concrete and further damage. Denver polyurethane concrete leveling can make a difference, and it’s a much more cost-efficient method of bringing the concrete back to the right height.
