Taking measures to rehabilitate faulty manholes rather than installing new structures can lead to substantial savings for municipalities. Here are several lining systems, sealants and epoxies, manhole components and installation safety equipment designed to aid in rehabilitation.Manhole LinersConcrete pipe lining systemThe CentriPipe structural concrete pipe lining system from AP/M PERMAFORM provides a no-dig solution for underground infrastructure rehabilitation. It uses a bidirectional spincaster to centrifugally compact a precision liner at the proper design thickness for the size, shape and conditions of deteriorated pipe. It inhibits rust, waterproofs and seals, is resistant to abrasion, and structurally reinforces and protects round, arched
