Repair or replace your concrete driveway?
If your drive has a few hairline cracks and still sits flat, it usually doesn't need replacing yet, and cutting out one bad section can buy you time. When slabs have sunk, tipped toward the garage or broken into pieces that rock under the tires, the trouble is underneath, and patching the top won't reach it. That's when I'd tear it out and rebuild from the base up, because new concrete on the same tired dirt just repeats the problem.
