Sunken or settling concrete and uneven footings can cause dangerous obstructions and tripping hazards.

Soil consolidation or soil erosion over a period of time contributes to concrete settlement, especially in locations with improper drainage. Sidewalk or patio slabs might pitch down, directing water towards the basement level. Another major cause of uneven concrete surfaces is seismic activity, especially in earthquake-prone areas. Even tree roots can heave a slab upwards.

Concrete leveling can correct an uneven concrete surface by altering the foundation that the surface sits upon. It is a cheaper alternative to having replacement concrete poured, saving you time and money.

The PolyLevel® System is a state of the art approach to repairing sinking concrete. Small holes are drilled in the slab and high-density expanding polyurethane foam is injected into the void using specialized equipment. The holes are then grouted and sealed with cement.

The polyurethane foam attains 90% efficiency in just 15 minutes after completion of the injection whereupon it expands and lifts the slab. The affected area is not only ready for normal use but suitable for heavy traffic as well.
