What Does
Spot Repair Mean?
Spot repair is the localized restoration of a pipe. It is a method of trenchless rehabilitation that eliminates the need for pipe replacement. Spot repair is an effective way to deal with defects that inevitably occur in aging pipelines.
Spot repair is also known as sectional point repair or localized repair.
Trenchlesspedia Explains Spot Repair
Close inspection of pipes is essential to maintaining the integrity of utility infrastructure. This may be done through a process called pigging, which sends a mechanical device into the pipes for cleaning or inspection. A smart pig, or intelligent pig, uses sensors and state-of-the-art techniques to detect anomalies in the structure of the pipe. Once a defect is discovered, two options are available: repair or replace.
Spot repair is often sufficient and can save money over replacement. Advances in trenchless rehabilitation have made localized repair a viable option. Methods include pipe rehabilitation technologies such as segmental sliplining, cured-in-place-pipe (CIPP) or mechanical spot repair.
