- Constrained Site
- Integrated Manholes
After approximately 39 years of in-ground performance, 11 of the 13 Polymer Coated CSP crossings (14 total pipes) had a rating of 2 (fair with some wear, but structurally sound). One of the culvert inverts could not be observed, one was a twin culvert, and one of the culverts observed had a rating of 3 due to foundation of the roadway surface unrelated to the pipe.
When comparing the current condition of the polymer coated CMP to the plain galvanized end sections used on the inlet and outlet of the pipes, it is apparent the polymer coating has helped significantly increased the service life of the galvanized culverts. If these culverts were made of galvanized steel they would have probably already been replaced.
Based on the overall condition of the culverts after 40-years of performance and the very good condition of the polymeric coating on the interior of the pipes, it is believed the culverts will continue to perform for many years to come.
