Final answer:
Cured-in-place pipe liners can be used to repair collapsed or compromised cast iron pipes. The process involves inserting a flexible liner into the existing pipe and curing it in place to create a new, structurally sound pipe within the old one.
Step-by-step explanation:
Cured-in-place pipe liners can be used to repair collapsed or compromised cast iron pipes. The process involves inserting a flexible liner into the existing pipe and curing it in place to create a new, structurally sound pipe within the old one. The liner is typically made of a resin-saturated felt material that hardens and forms a protective barrier.
This method is commonly used in sewer and water pipe rehabilitation to extend the life of existing infrastructure without the need for excavation and replacement. It is a cost-effective and efficient solution that can effectively repair cast iron pipes.
For example, if a section of cast iron pipe collapses due to corrosion or root intrusion, a cured-in-place liner can be installed to seal off the damaged section and restore the pipe's integrity. The liner acts as a new pipe within the old one, preventing further leaks or collapses.
