Reline of Storm Culverts, CSO, and Small Bridges - The "New" Approach to Trenchless

Don LeBlanc, P.E., P.E., M.ASCE

This presentation is an inside look at some new and exciting engineered liner technologies for storm, combined sewers, and small bridges. The presentation begins with a brief comparison of traditional ‘dig and replacement of a structure’ versus sliplining/reline of the host structure. We will review basic applications and will answer proper design questions that engineers should ask themselves when considering a culvert for a lining candidate. Many project profiles will showcase unique engineering challenges and the versatile solutions that were used to meet the project parameters.
