Sidewalk & Patio Cracks Explained
Sidewalk and patio cracks are common and often harmless — but they can flag drainage and soil issues worth addressing before they reach the house.
Reading the cracks
Hairline and joint cracks are normal; heaved sections, trip-hazard offsets, and cracks that radiate from the house suggest soil movement.
The fix
Concrete repair handles flatwork; if the cracking tracks toward a moving slab, that’s slab repair territory.
Prevent recurrence
Correct drainage and grade so water stops undermining the base.
- Joint cracks are normal; offsets are not.
- Flatwork is repaired; moving slabs use piers.
- Fix drainage to prevent recurrence.
