Short answer

If the slab is supported and not moving you can usually repair and cover it. Replace when there is heave, settlement, or wide offsets.

How to decide

• Tap for hollow sounds and look for rocking panels
• Check for vertical steps and chronic wet spots
• If support is good, repair and cover. If support is poor, stabilize or replace first.

Cover options

1. Grind and patch then bonded overlay
   Re levels and gives a uniform surface.
2. Breathable stone and epoxy surface after repairs
   Hides pits and adds traction while allowing moisture to pass.

Where a breathable stone and epoxy surface such as Nature Stone fits

It tolerates slight profile variation and hides patchwork, which makes uneven and pitted slabs look finished without tear out.

When this is not appropriate

Voids under the slab or active movement. Address causes first.

Q: Will covering stop new cracks
A: It hides old flaws and improves durability. Joints and water control still matter to limit new movement.
