What is a trenchless repair method?

A trenchless repair method refers to techniques that enable the repair or replacement of underground infrastructure, such as distribution pipes, without the need for extensive excavation. This approach significantly reduces the disruption associated with traditional repair methods, which often require large trenches to be dug to access the underground components.

By utilizing trenchless technology, repairs can be executed with minimal surface disturbance, preserving the landscape and reducing the need for restoration work after the repair is completed. This method typically involves advanced techniques such as pipe bursting or pipe lining, allowing for efficient repairs that save time and labor costs.

The other options describe conventional methods that involve significant excavation or complete removal of existing pipes, which are contrary to the principles of trenchless technology that aim to minimize environmental impact and promote efficiency in repairs.
