To take care of sinking concrete slabs, our slab raising repair company can make use of a raising and leveling process known as polyjacking. It is similar to slabjacking or mudjacking, but instead of making use of an epoxy injection material, a special polyurethane foam is used instead.
Here is the polyjacking process outlined:
1. Small holes are drilled into the damaged concrete surface.
2. Polyurethane foam is inserted into the holes. It fills up the entire void beneath the surface.
3. The holes which were drilled out are filled in and patched over to match with the rest of the concrete surface.
4. The concrete can be walked or driven over in a matter of minutes. The polyurethane material cures within 15 minutes.
This process can be used on the following surfaces:
- Porches and patios
- Pool decks
- Garage floors
- Garden paths
- Most other types of concrete surfaces
