Advantage vs Lifting

Georgia Safe Sidewalks

No underground contact at all, no risk of damage to utilities.
Much less expensive.
Does not change the elevation of the sidewalk at all.
Leaves a flush joint every time.

Lifting/Jacking

Lifting of sidewalks has a reputation for damaging underground utilities.
Lifting is expensive, almost equivalent to the cost of demolition and replacement.
Lifting frequently elevates the sidewalks 3-4” above the surrounding turf creating new safety issues to pedestrians.
Very difficult to obtain flush joint on cross-joint hazards. Frequently end up grinding the joint anyway.
