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.
