Concrete leveling – also known as mudjacking — is a proven, cost-effective method that’s commonly used to repair settled slabs in Salt Lake City. Cracked patios, tilted driveways, sunken sidewalks and uneven garage floors are just a few of the issues that can be resolved with this professional technique.
If you’re unfamiliar with concrete leveling, you’re certainly not alone. In our experience, many people first come across the repair method when researching ways to fix a damaged slab. And, more than a few are surprised to find out that mudjacking has been in use since the 1930s. Here’s a look at how the process works to raise and stabilize settled concrete.
Step 1: GPR Survey
Ground penetrating radar (GPR) is a non-invasive imaging technique that provides a map of what’s underneath a damaged slab. The equipment allows professional concrete repair contractors to detect the location of voids or empty spaces in the soil.
Step 2: Drilling Holes
To restore a sunken or settled slab back to an even position, several holes must be drilled through the surface. The holes for concrete leveling are small, about two inches in diameter, and they’re usually placed two to four feet apart across the slab.
Step 3: Filling Voids
After the holes have been drilled, the voids underneath are accessible – and to lift the slab and make it stable, those spaces are filled with a specialized grout. The mixture is hydraulically pumped through the holes, and the resulting pressure raises the concrete.
Sealing the Stabilized Slab
Technically speaking, the concrete leveling process is complete when a slab is returned to its original position. But in our view, the work isn’t finished at this point. Any extra grout needs to be wiped away, of course, but more importantly, the surface needs to be sealed.
If the drilled holes and the cracks in the slab aren’t filled and sealed after concrete leveling, water can easily seep down into the soil. Exposure to rain and melting snow can create more problems down the line, leading to the development of new voids and concrete cracks. When a slab is properly sealed, the risk of future settlement – and the need for additional concrete repair — is much lower.
