Trenchless sewer repair uses modern techniques to restore sewer lines without the need for large trenches. The two primary methods are pipe lining and pipe bursting, and the best option depends on the condition of the existing pipe.
Pipe lining, also known as cured-in-place pipe (CIPP), involves inserting a flexible liner coated with resin into the damaged sewer pipe. The liner is inflated so the resin presses against the interior walls of the pipe. Once cured, it forms a smooth, durable new pipe inside the old one, sealing cracks and preventing leaks.
Pipe bursting is used when the existing pipe needs to be replaced rather than repaired. This method breaks apart the old pipe while simultaneously pulling a new pipe into place along the same path. Both trenchless techniques avoid extensive excavation and help preserve landscaping, driveways, and sidewalks.
For Denver-area homeowners, trenchless sewer repair is often recommended when conditions allow because it reduces repair time, limits disruption, and provides a long-lasting solution. A sewer camera inspection is typically used first to determine which trenchless method, if any, is appropriate for a specific sewer line.
