relined

Relined refers to the process of reinforcing or repairing an existing pipe by inserting a new lining within it. This technique is commonly used in plumbing and sewer systems to address issues such as leaks, corrosion, or structural weaknesses without the need for extensive excavation.

The relining process typically involves cleaning the existing pipe to remove debris and prepare its surface. Then, a new liner, often made of resin-saturated felt or other flexible materials, is pulled or inverted into the old pipe. Once in place, the liner is cured, usually through the introduction of hot water, steam, or ambient air, causing it to harden and form a seamless, durable new pipe within the old one. This creates a sealed barrier that prevents leaks and restores the pipe's structural integrity.

Relining offers several advantages over traditional pipe replacement methods. It is significantly less disruptive, requiring minimal digging and often avoiding damage to landscaping or surrounding structures. This can lead to reduced labor costs and a faster completion time. The new liner is typically resistant to corrosion and root intrusion, potentially extending the lifespan of the pipe system. It is a common solution for both residential and commercial properties facing aging or damaged underground pipes.
