Best Practices to Manage Effects of Settlement and Heave at Catch Basins and Manholes

As noted by the Local Road Research Board (LRRB), the most recent implementation study on manholes is an LRRB study by Cruse (2001). In addition to being out-of-date, the study does not address catch basins. The study provides a four-page overview of manhole ring/sealant products and a three-page discussion of the dislocation of rings due to construction or frost heave. Recommendations to remediate compromised manholes are restricted to just over one page, with no representative field examples from Minnesota municipalities. Most publicly available resources on manholes and catch basin installation are promotional literature or articles from industry publications. To address this need, this project will produce a resource that (A) discusses installation techniques that prevent settlement or heave near catch basins and manholes, (B) documents the experiences of Minnesota municipalities with catch basins and manholes, and (C) documents available catch basin and manhole products. We have considered these needs alongside our understanding of the project background, stated below.
