Why SuperCover is a Best-Selling Manhole Cover
Unmatched Durability and Safety Features
Unlike traditional manhole covers, SuperCover is built using cutting-edge composite materials that offer superior strength without the drawbacks of cast iron. Our covers are HS-25 traffic-rated, meaning they can withstand heavy loads without cracking or warping. Additionally, the bolted safety dish and double-gasket seal provide extra protection against unauthorized access and environmental wear, ensuring long-term reliability in high-traffic areas.
Eliminating Common Infrastructure Challenges
Many municipalities face costly repairs due to sewer system failures caused by water infiltration and pressure fluctuations. SuperCover’s innovative design prevents sewer drain cover issues by significantly reducing I&I, which helps lower water treatment costs and prevent flooding. Our alignment tabs ensure a secure fit, minimizing shifting or loosening over time. By choosing SuperCover, cities can proactively address these challenges and extend the lifespan of their wastewater systems.
No Scrap Value — Reducing Theft Risks
Traditional sewer covers made of iron are often targeted for theft due to their high scrap value. SuperCover eliminates this concern with its non-metallic, composite construction. This feature not only protects municipal infrastructure but also reduces replacement costs and downtime caused by stolen covers. Cities can rest assured knowing their investments remain secure.
Tested, Approved, and Trusted Nationwide
SuperCover is backed by rigorous testing from leading organizations, including the Texas Department of Transportation (TxDOT) and Louisiana Tech University’s Trenchless Technology Center. Our commitment to quality ensures that every manhole cover we produce meets or exceeds industry standards for safety, durability, and efficiency. Municipalities trust SuperCover to deliver reliable solutions that support long-term infrastructure stability.
