Concrete is presented as a low-cost material for use as a sole tunnel liner material in future mass transit tunnel projects. Existing mass transit tunnels throughout the world which have used concrete liners are presented. A systems summary is given which outlines numerous factors that must be considered for implementation of concrete as a sole tunnel liner material. Various concretes and liner sealant systems are presented as well as past and current research efforts directed toward greater use of concrete in future transit tunnel projects. Many aspects for consideration in a sealant system test verification program are also presented.
