Old Slab Repair, Concord, MA

The concrete apron leading to a raised garage floor was cracked at the mid point and sunk about 2-3in on one side. The slab is 8 feet long and 18 ft wide with a slope up of 1ft from the gravel drive to the wooden garage floor. The slab is cracked and sunken on the left half, which has been undermined by poor drainage from the adjoining barn.
