Settled Cement Slab
If your driveway, sidewalk or patio has a large area of concrete that has settled unevenly and now has a pitch towards your home foundation and threatens to flow rain water towards the basement. It may be that your home inspectors recommendation that the condition is a candidate for mudjacking.
Mudjacking is a process that utilizes hydraulic pressure to raise or level concrete slabs and sidewalks. A series of holes approximately 2 inch holes are drilled through the slab a pre determined locations. A mixture of water, ground stone and cement is pumped through the holes with a special machine. The stiff mud that is pumped under the slab will lift it to the desired location or slope.
If you have a slab that is in relatively good condition with few cracks, mudjacking can be a more cost effective way of correcting the problem than replacing the slab. Done correctly, the repair will last for years
