Pipe Lining Process

Pipe lining, also known as Cured-In-Place Pipe lining (CIPP), is a trenchless rehabilitation method. It involves the insertion of a fabric polyester tube saturated with self-hardening epoxy resin into the existing pipe. After installation, the lining is cured to form a new pipe within the old one, extending the pipe’s lifespan significantly. Brands like Perma-Liner offer a 50-year warranty for this service, making it a reliable long-term solution (Trenchless Pipelining). The process is also less invasive than traditional methods, preserving property and minimizing disruption. For a comprehensive understanding of cast iron pipe repair, visit our information hub.

Pipe Bursting Technology

Alternatively, if pipe lining is not feasible due to the condition of the pipes, pipe bursting technology offers a solution for complete replacement. This method involves pulling a new pipe through the old one, with a bursting head leading the way to fracture the existing pipe and immediately lay down the new line, usually made of high-density polyethylene (HDPE). Although effective, pipe bursting can be more destructive to incoming pipe connections and might require manual replacement, potentially leading to longer downtime compared to pipe lining (Trenchless Pipelining).

Both trenchless methods, pipe lining and pipe bursting, are innovative solutions that allow for the replacement of cast iron drains with minimal damage to property and reduced time compared to traditional methods. Homeowners should consider these options when weighing the benefits of cast iron pipe replacement against traditional excavation methods, which involve digging through floors and can be significantly more disruptive.
