Fix the section, fix the cause.
Most concrete damage is local. A corner sinks where a downspout empties, a panel heaves over a tree root, or a section cracks where trucks turn. Replacing only the damaged panels, and fixing whatever caused the damage, is often the most cost-effective option.
What gets repaired
- Sunken or settled panels: cut out, base rebuilt and compacted, new concrete poured
- Heaved sections and trip hazards: removed and re-poured level with the surrounding slab
- Cracked panels: replaced from joint to joint so the repair looks intentional
- Broken edges and aprons: rebuilt where the driveway meets the street or garage
- Damaged steps: repaired or re-formed
Finding the cause
If water from a gutter is washing out the base, a new panel will sink again. Part of every repair estimate is figuring out why it failed, whether that's drainage, roots, a missing base or heavy loads, and addressing it.
When replacement makes more sense
If damage is spread across most of the slab, patching it piece by piece gets expensive and still leaves an old surface. In that case you'll get a straight comparison of repair vs. full replacement so you can decide.
About color matching
New concrete is lighter than old concrete at first and darkens as it weathers, so a repaired panel will stand out for a while. Replacing full panels between existing joints keeps the repair looking clean.
