Oldcastle Polymer® is produced using a precise dry mix of select gravel and sand, which is bound with resin and fiberglass fabric. This manufacturing process yields a composite capable of meeting both Tier 15 & Tier 22 traffic ratings while remaining lighter than concrete.
Oldcastle FRP® enclosures are produced in a unique hybrid process bonding strong, polymer concrete rings with high-impact resistant fiberglass sidewalls, forming a monolithic body. Paired with a polymer concrete lid, select units are suitable for light or heavy incidental traffic. Specifiers can meet expected load ratings while installers can handle and modify with ease.
