Mudjacking is the process of drilling holes in the curb/gutter, then pumping mud and concrete into the holes to make the gutter level with the road surface. One major reason this is done is to help eliminate pooling water in areas that are lower than the storm sewer drains; these areas can serve as mosquito breeding grounds. This method does not always work, especially in areas where sump pump discharge water is abundant. When mudjacking fails, the Engineering Department may undertake a street rehabilitation project in the area.
Another reason for mudjacking is to level the curb/gutter for the Engineering Department before a street rehabilitation project.
