The Job Site: Jacking and Leveling a Concrete Slab

This is the stage of leveling a concrete slab – an important part of foundation repair in Houston. After the concrete has cured for approximately 10 – 14 days, the jacking and leveling crew will arrive. They will set two concrete blocks and a hydraulic jack on top of each pier and raise the house as near to the original grade as possible. All piers will be shimmed and adjusted by our skilled crews until the house or building is as level as possible.
