**Direct answer:** Pipe lining (CIPP) repairs a damaged sewer by installing a resin liner inside the existing pipe, creating a new, jointless pipe within the old one—usually with minimal digging. It’s often used for cracks, joint leaks, root intrusion, and corrosion when the line still has a usable shape.
