There are several options for trenchless sewer repair, and different methods work well in different situations.
- Sewer relining. This common trenchless pipe repair method can be used to patch up cracked sections of leaking sewer pipe. Pipe lining involves inserting a flexible tube made from fiberglass and resin, which is hardened after it’s set into place. This can be done through small entry points, without any extensive digging. Relining is suitable for sewer pipes that are damaged, but retain most of their overall structural integrity.
- Pipe bursting. Pipe bursting is a trenchless sewer replacement option for severely damaged pipes. A piece of hydraulic machinery called a bursting head is used to break the old pipe apart and push it away. Behind it, a new segment of pipe is pulled into its place. This method is suitable for replacing up to 400 meters of pipe.
Trenchless repair methods can fix many common problems with sewer lines, including:
- Pinhole leaks and cracks in the sewer pipe.
- Burst sewer pipes
- Damage from tree root growth
- Structural damage to entire sections of pipe
- Corrosion and scale in old metal pipes
Trenchless sewer leak repair has several benefits over repair methods that require excavation, including:
- Keeping your lawn and landscaping intact. Sewer excavation is inherently disruptive, and for homeowners who’ve put a lot of time and money into their lawn and garden, this can be a major headache. After the pipe is fixed and the soil is back in place, it can take weeks or months for grass to regrow in the area. With trenchless sewer repair, plumbers can bypass the need to dig up your yard.
- No damage to driveways and patios. If your sewer line runs beneath your driveway or patio, excavation is a problem. Trenchless repairs allow plumbers to access sewers and drain lines that run below a driveway, without breaking apart the concrete. This can save you quite a bit of money and time.
