I am currently working on a project that involves repairing the concrete walls of a sanitary sewer interceptor structure and line pipe and was wondering if you had any reference information regarding shotcrete being used to repair similar items and how well it has held up. Any information you send will be greatly appreciated.
Shotcrete, both wet- and dry-mix, have been used to repair and reline sewer structures for many decades and has held up well as a lining or repair material. It is important to have the work done by a qualified shotcrete specialty contractor and to specify a durable concrete mixture design.
