A cracked drain under the driveway. The usual fix is a trench. Old drains fail in a few familiar ways: cracks, open joints, and roots growing in. Lining fixes them in one pass. A flexible tube, soaked in resin, goes in through the access point. Air or water pressure turns the tube inside out as it travels, and presses it onto the wall. Then the resin cures in place. What's left is a new, jointless pipe, inside the old one. So which one? Say the camera finds one cracked joint, and the rest of the pipe is sound. Digging it up is the slowest route. A full-length liner would line pipe that isn't broken. A sectional patch fixes the point. If the cracks run the whole length, the answer flips: line the run. The full explainer is on our channel.
