Gary dives into home maintenance and repair with a focus on outdoor drainage systems. He discusses a listener's issue with a driveway sealer that's peeling off, and shares a potential solution involving a high-pressure washer or grinding it off with machinery. Gary also talks to Dave Crook from Precision Pipeworks about trenchless sewer and drain repair, a technology that can fix pipes without digging. They cover common issues with sewer lines, including root growth and blockages, and how this method can be a more cost-effective and less invasive solution.
