The cheapest manhole to buy is rarely the cheapest manhole to own. Over 60 years, polymer concrete wins on total cost.
Traditional lined concrete manholes in corrosive conditions typically need rehabilitation every 10–15 years. Across a 60-year life, those repeated interventions can stack up to $12,000–$24,000 or more per structure.
A polymer concrete manhole is installed once for a comparable up-front figure of around $5,000 — and then needs virtually no maintenance for the life of the asset.
When you compare like-for-like over the full service life, PRC delivers the lowest life-cycle cost by a wide margin, while removing the disruption and risk of repeated rehabilitation.
