I've got one slab of sidewalk, about 30x48, that has drifted away from the front
porch. I'm looking for techniques to force it back, about 2", if possible.
Drive a wedge into the ground in front of it, and periodically pound it further
into the soil?
Attach a come-along to an edge, and slowly winch it closer?
Use a big ass pry bar and brute force?
