What method can be used for non-intrusively repairing pipelines?

Trenchless technology is an innovative approach widely used in the repair and installation of pipelines without requiring extensive excavation. This method allows for the rehabilitation or replacement of existing pipelines while minimizing surface disruption.

With trenchless technology, techniques such as horizontal directional drilling, pipe bursting, or sliplining are employed. These methods enable engineers to maintain the integrity of the existing infrastructure and reduce environmental impact. Since the process can be completed with minimal digging, it avoids the complications and costs associated with traditional trenching, making it a preferred option for pipeline repairs.

The other methods, while they may have their uses in pipeline maintenance or installation, typically involve intrusive digging or significant alteration to the surrounding area, which is contrary to the idea of non-intrusive repair.
