Manholes are hollow concrete tubes that are installed vertically below grade and are lidded with a round cast iron lid at street level. They are placed at vault openings or pipe junctions and provide maintenance and inspection access to underground piping systems.
Oldcastle Precast manufactures a variety of manholes with various coatings and design components for use in different applications. Manholes designed and manufactured at Oldcastle Precast meet ASTM C 478 specifications, AASHTO HS-20 live load criteria, and NPCA & ACPA certifications. Our manholes are made with type I or II cement unless otherwise specified. Custom and standard sizes are available.
