Great Question!
A-1 Concrete Leveling is a process which hydraulically lifts your existing concrete walk, drive, steps, etc. to its original position. Through a small hole about the size of a quarter, our evnironmentally safe mixture is pumped, and floats your hazardous, unsightly area into place.

Small holes are drilled in the sunken concrete.
A-1 pumping compound is pumped from out truck into each hole. The compound works hydraulically underneath the concrete, raising is back to its original position.
Once the desired result is obtained, the holes are sealed off using a durable cement mixture.
You can even use the repaired concrete the same day!
