At Quality Waterproofing we offer two separate solutions to repair sinking or cracked concrete surfaces on driveways, patios, porches, garage floors, and more. These solutions are mudjacking and polyjacking. While we may think of concrete as a strong and durable material, it can still experience problems due to several factors:

  • Poor Compaction
  • Age
  • Wear and tear
  • Soil Shrinkage
  • Moisture

Different types of soil can support different amounts of weight. If the soil around your home was not compacted properly after construction or has become compromised after years of water entering and leaving the soil, it can have problems supporting the concrete above it.

The damaged surface that you see not only looks terrible, but it can also cause a variety of problems for the rest of your home. This damage could be an indicator of other problems such as soil or drainage issues, internal problems with the concrete, or improper setup or reinforcement. Additionally, sinking slabs could pose a tripping hazard to family members and guests to your property. As you can see, it's important to get these problems taken care of immediately before the damage gets worse.

Common Problems Caused By Sinking Concrete Slabs

  • Concrete cracks
  • Uneven concrete slabs
  • Uneven walkways and sidewalks
  • Sinking garage
  • A sinking stoop
  • Uneven stairs

Fortunately, all these issues can be fixed with our concrete raising methods.


Mudjacking (also referred to as slabjacking, concrete raising and leveling) is the process of raising concrete slabs by hydraulically pumping a grout mixture, usually sand-based material infused with cement, under the slab of concrete. First, small holes are measured and spaced appropriately, then drilled into the slab. Secondly, the slurry (a grout mixture of water and cement) is pumped through the small holes, where it will fill any voids underneath the slab. The slab will be pumped until it is leveled. Finally, the small holes are patched with cement and the work area is cleaned up. The slurry will be cured ready for traffic after 24 hours.


Polyjacking is a more state of the art version of mudjacking except instead of a cement slurry being forced in and lifting the slab, an expanding polyurethane foam is used which is lighter and more effective than the cement slurry. The holes drilled in the slab for polyjacking are much smaller than those used for mudjacking which will make them ultimately less noticeable.
