Practical Design Approach to Coatings & Liners for Manholes

The lack to date of an industry produced design standard for coatings and linings used in the renewal of sanitary sewer manholes by the manufacturers/suppliers of these technologies has created a desire within the engineering community to find a methodology, or methodologies, which can develop this needed engineering skillset. This paper presents a pragmatic discussion regarding uses for coatings and linings with respect to buried structures and gets back to the basics by defining them with respect to their in place performance.
