Government Agencies and Others Reduce Costs By Sliplining

Culvert rehabilitation by sliplining has experienced increasing use throughout Canada. The increased usage is due to higher traffic density, social and environmental impacts and high construction costs associated with open-cut techniques. This paper will explain the benefits of sliplining an existing culvert as well as the features the designer/installer should look for in a liner. Culvert sites that are suitable for this type of Trenchless technology will also be explored. Additionally, several culverts sliplining projects recently completed in Canada will be covered with emphasis on the design and construction issues.
