Trenchless sewer repair is a modern method of repairing or replacing damaged sewer lines without the extensive digging associated with traditional methods. Instead of excavating a large trench, trenchless techniques use specialized tools to access and repair the pipe from a few small access points.
Here’s a breakdown of the common trenchless methods:
- Pipe Lining: A new, flexible pipe liner coated with resin is inserted into the damaged pipe. The liner is then inflated and cured (hardened) in place, creating a new, durable pipe within the old one.
- Pipe Bursting: A bursting head is pulled through the damaged pipe, breaking it apart while simultaneously pulling a new pipe into its place.
Benefits of Trenchless Sewer Repair:
- Less disruption: Minimal digging means less damage to yards, landscaping, driveways, and other property features.
- Faster repair time: Trenchless methods are generally faster than traditional excavation.
- Cost-effective: Reduced labor and restoration costs can make trenchless repair more cost-effective in the long run.
- Long-lasting: Trenchless repairs often use durable materials like HDPE, which can last for many years.
Trenchless sewer repair offers a less invasive and often more efficient way to address sewer line problems compared to traditional excavation.
