Pipe lining is a method used to repair and reinforce existing pipelines without the need for extensive excavation. This technique involves inserting a flexible liner coated with resin into the damaged pipe. Once in place, the liner is inflated and cured, creating a new, durable inner surface that can extend the life of the pipeline. This process is commonly used for various types of pipelines, including those for water, sewage, and gas. By minimizing disruption to the surrounding area, pipe lining is often a more cost-effective and efficient solution compared to traditional pipe replacement methods.
