Mudjacking, also known as concrete raising, slabjacking or concrete lifting has been a cost-effective option for removing or replacing your uneven or sunken concrete. Unfortunately, a wide number of homeowners have been unaware of how mudjacking works. They may not be aware why it has been an effective option for your concrete repairing needs. Let us delve into and learn a thing or two about mudjacking.
Initiation of the process
The process became popular in the late 1920’s and early 1930’s. It has been a mode for repairing sunken concrete on highways. It would be used for filling voids under the slabs of concrete. You could find pictures of the process in various parts of the world. It has been widely popular across the world in the present times. The process has been deemed as highly cost-effective repair for uneven and sunken concrete.
When to use the process
When you see concrete settling in or causing hazard or experience the sub grade of your driveway eroding and causing cracks or voids, you do not have to remove the sunken or voided concrete slabs or replace them. Your best bet in such a scenario would be having them mudjacked.
The process would entail a few simple steps. It would be inclusive of some special equipment inclusive of small mudjack pump that has been specifically designed for precisely pumping the grout or polyurethane in a controlled manner. The procedure would need grout and some small hand tools. A majority of contractors would typically make use of small dump truck or truck-and-trailer combo for completing their jobs. There would be larger and more contained truck on the market designed to mix and pump at the same time. Because of the higher cost of this truck, a majority of mudjackers would make use of truck-and-trailer method.
How it works
Let us understand how it works.
- The small holes would be drilled through the concrete slab. A standard slab would require up to six holes.
- The grout or polyurethane mixture would be pumped in holes with pressure to fill the voids. With the pressure building up, hydraulics would take over and the slab would rise up to its original height. The concrete slab would be lifted and supported by the grout or polyurethane pumped under it.
- The drilled holes would be discreetly patched with concrete mix. It would blend in easily.
- The mudjacked concrete would be ready to use. Sidewalks would be made walk ready.
