Key takeaways
- Sound slabs with narrow cracks can be repaired
- Settled slabs can sometimes be lifted
- Badly broken or heaved slabs call for replacement
- Fix the cause so the problem does not return
The right answer depends on what the slab is doing and why.
Repair
If the slab is mostly sound and the cracks are narrow, filling and sealing can extend its life.
Lift and level
If a slab has sunk but is not broken, it can often be raised back to level.
Replace
If the slab is broken up, badly heaved or has a failed base, replacing is usually the better value.
Fix the cause
Drainage and base problems have to be fixed too, or the problem returns.
