Repairing or replacing a concrete parking lot
If the cracks are few and the slab around them still sits level, cutting out and replacing the bad sections is usually the sensible choice. When large areas have sunk, water pools across the lot, or the old pavement was simply too thin for the trucks using it now, patching only moves the problem. In that case I'll tell you plainly that a new lot on a properly prepared base is the better use of your money.
