Cast Iron Pipe Lining
Cast iron drains and stacks rust, scale and crack. A liner gives them a new smooth wall without opening floors and ceilings.
The details, in plain English.
Cast iron was the standard for building drains and sewer lines for generations. It is strong, but it corrodes from the inside, building rough scale that narrows the pipe and eventually leaks.
Lining restores cast iron without demolition. After descaling, a liner forms a smooth, corrosion-proof pipe inside, sealing pinholes and cracks. It is especially valuable for stacks and under-slab lines that are costly to reach.
