Small, Minor Cracks
Generally, cracks that are as wide as 1/4 of an inch are not a big problem. Cracking of the concrete is inevitable and usually controlled via control joints.
Control joints are intentionally-included weak points in the concrete that guide the way that these inevitable cracks form. This way, the damage is less likely to be unpredictable or extensive.
Such small, hairline cracks needn’t even be repaired in most cases. If you wish, though, you can have them patched up.
Cracks that are wider than 1/4 of an inch should definitely be patched up. However, if the crack is wider than 2 inches, it’s most likely beyond repair and should be replaced.
If the crack runs all the way through the slab, the slab is completely broken. You may also notice plants growing up through such cracks.
When cracks are this deep, they let moisture trickle down into the sub base. Then, the whole sidewalk can start deteriorating very rapidly. If you see any such cracks, replace the slab and have the sub base inspected.
Numerous cracks that look like spiderwebs are a sign of failed concrete. That is, the cracks obviously aren’t following along the designated control joints. The only thing you can do about this is to replace the slab.
Small areas (less than half an inch) of crumbling along the edges of a slab are a repairable issue. However, if you notice large/numerous crumbling areas appear in a very short amount of time, you have weak concrete. In this case, get it replaced.
When certain slabs lift higher than others, these uneven slabs are a tripping hazard. The key to fixing this, however, is to determine why it’s happening.
For instance, if moisture is collecting underneath the raised slab, find out where it’s coming from and divert it. Or, if it’s being pushed up by a tree root, have the tree removed.
Old Concrete Slabs
Before you repair any of the minor damage on this list, consider the concrete’s age. If it’s several years old, it’s probably more cost-effective to get it replaced.
