Definition - What does No-Dig Repair mean?
No-Dig repairs are a subset of trenchless repair techniques in which underground pipes are repaired or replaced with little to no excavation trenches. In many cases, pipes can be repaired while in-place with a variety of specialized tools, equipment and materials with minimal disruption to traffic, business and other activities.
Trenchlesspedia explains No-Dig Repair
No-Dig repairs directly contrast the traditional methods of pipeline repair which often require large excavations and sizeable construction machinery. This often results in disruptions which can be lengthy and costly.
Some No-Dig pipe repairs methods include, but are not limited to:
- Cured In Place Pipe (CIPP)
- UV-Cure Spot Repairs
- Manhole & Catch Basin Relining
- Grout Injection of Manholes, Mains and Laterals
- Mechanical Joint Seals & Sleeves and
- Lateral-to-Main Connect Utilizing UV Technology
This method of pipe repair has significant advantages to traditional excavation based repairs including:
- Reduced disruption and downtime
- Reduced overall cost
- Minimum disruption to the existing landscape
- Ability to rehabilitate pipes while still in-place
No-Dig repairs may also be referred to as trenchless repairs.
