Trenchless Methods Overview
Trenchless sewer line technology encompasses several distinct methods, each suited to different situations and pipe conditions. Understanding these methods can help property owners make informed decisions about the best approach for their specific sewer line issues.
Pipe Lining (CIPP – Cured-In-Place Pipe)
Pipe lining, also known as Cured-In-Place Pipe (CIPP), is one of the most common trenchless repair methods. This technique involves inserting a flexible, resin-saturated liner into the existing damaged pipe. Once in place, the liner is cured using heat or UV light, creating a new, seamless pipe within the old one.
Process:
- The damaged pipe is cleaned and inspected using CCTV cameras.
- A flexible liner saturated with epoxy resin is inserted into the pipe.
- The liner is inflated, pressing it against the walls of the existing pipe.
- Heat or UV light is applied to cure the resin, hardening the liner.
- The ends of the new pipe are trimmed, and service connections are reinstated.
Ideal for:
- Pipes with minor to moderate damage
- Situations where increasing pipe diameter isn’t necessary
- Repairing cracks, small holes, and joint separations
- Preventing root intrusion and sealing leaks
Advantages:
- Minimal excavation required
- Can navigate through bends and turns in the pipe
- Smooth interior surface improves flow capacity
- Prevents future root intrusion and seals leaks
Limitations:
- Not suitable for completely collapsed pipes
- Slight reduction in pipe diameter (typically negligible)
Pipe Bursting
Pipe bursting is a trenchless method used to replace an existing pipe with a new one of the same or larger diameter. This technique involves pulling a new pipe through the old one while simultaneously fracturing the old pipe outward.
Process:
- Access pits are dug at the start and end points of the pipe section.
- A bursting head is inserted into the existing pipe.
- The bursting head is pulled through the old pipe, fracturing it outward.
- A new pipe is pulled behind the bursting head, replacing the old pipe.
- Service connections are reinstated, and access pits are filled.
Ideal for:
- Severely damaged or collapsed pipes
- Cases where increased pipe capacity is desired
- Replacing pipes made of brittle materials like clay or cast iron
Advantages:
- Allows for upsizing of the pipe diameter
- Completely replaces the old pipe with a new one
- Can be used for longer pipe sections
Limitations:
- Requires more access points than pipe lining
- May cause some ground movement, which could affect nearby utilities
Slip Lining
Slip lining is one of the oldest trenchless rehabilitation methods. It involves inserting a smaller, “carrier” pipe into the existing, larger “host” pipe.
Process:
- The host pipe is cleaned and inspected.
- A new, smaller pipe is inserted into the existing pipe.
- The annular space between the new and old pipe is typically grouted.
- Service connections are reinstated.
Ideal for:
- Pipes with minimal bends or turns
- Situations where some reduction in pipe diameter is acceptable
Advantages:
- Simple and cost-effective for straight pipe sections
- Can use various pipe materials for the new liner
Limitations:
- Reduces the pipe’s internal diameter
- Not suitable for pipes with significant bends
Pipe Relining
Pipe relining is similar to CIPP but uses a slightly different approach. Instead of a flexible liner, it uses a rigid pipe liner that’s slightly smaller than the host pipe.
Process:
- The host pipe is cleaned and inspected.
- A new, rigid pipe liner is inserted into the existing pipe.
- The liner is expanded to fit tightly against the host pipe.
- Service connections are reinstated.
Ideal for:
- Pipes with minimal diameter reduction requirements
- Situations where a more rigid liner is preferred
Advantages:
- Provides structural stability to the existing pipe
- Can be used with various pipe materials
Limitations:
- Slight reduction in pipe diameter
- May require more access points than CIPP
