Should you repair, resurface or replace the slab?
A simple way to decide is to check three things: movement, depth of damage, and extent.
- Movement. If the slab is level and solid, repair or resurfacing may work. If it has sunk, tilted or heaved, the cause must be fixed.
- Depth. Surface scaling and stains can be resurfaced. Cracks that go all the way through need to be filled or the section replaced.
- Extent. A few problem spots can be fixed one by one. If most of the slab is damaged, replacement costs less over the long term.
Some uneven slabs can be raised back to level by pumping a foam material beneath them, or the trip edge can be ground smooth. Others need to be removed and poured again. If replacement is the right answer, we will say so, and you can read about full driveway installation or new walkways. We do not push you toward the bigger job.
