Understanding Mudjacking

Mudjacking is basically the process in which a slab is raised by pimping concrete grout under the slab. If you replace the slab it will cost you double of what it costs for mudjacking. If you want to learn and get a better understanding of how mudjacking actually works then this article is what you are looking for.

If you think that replacing your slab is a better choice then think again, an aged slab is way tougher than a slab that is newly laid. It is cost effective as already discussed and a better option than tearing out your old slab and replacing it with a new one.

If you are looking for a place to get your slab mudjacked then mudjacking St Louis is a good place to look. Basically, in the mudjacking process, you are pumping the concrete slurry below the slab, this allows you to lift up your slab to the desired level.

The name mudjacking originated from the mud that is used in the slurry, the slurry consists of a relatively low strength mixture of the following:

  1. Cement
  2. Sand
  3. Structural Fill, also known as mud

In some cases, the slurry also consists of polyurethane foam, the foam releases bubbles when it is cured which allows the slab to be lifted up due to the pressure. This is a more precise method, however, if the foam is used then the whole process of mudjacking becomes expensive.

The first step is to make holes of 2 inch in the concrete slab and then the slurry is pumped in till it is raised to the desired level, after that the holes are cleaned thoroughly and then sealed by using cement. The cement used to close the holes is shrink-proof.
