Our slurry is a specially prepared blend of several types of earth that is the densest fill material we can get our hands on. It is denser than the existing ground on which your concrete sits and is ideal for the mudjacking application.
When mudjacking first started, it was thought that adding concrete improved the quality of the job. This has actually been proven false as the industry has developed over the years. The single most important part of mudjacking is to completely fill the voids under a slab in order to stabilize it. Adding concrete to the slurry mix actually increases the drag as the slurry travels under the concrete. This in turn means the slurry doesn’t flow as well and, as a result, doesn’t fill the voids as well. A straight sand, slurry mix with no concrete added actually flows much better under the slab resulting in a complete fill of voids under the slab which insure a better job that will last longer.
