Oldcastle Infrastructure’s manholes are versatile in the construction of buried structures. Manholes are often utilized at vault openings or pipe junctions to provide maintenance and inspection access to underground piping systems, meters, and facilities. The manhole sections are produced in quality controlled conditions to provide uniformity and performance unmatched in the industry. We offer a variety of manholes in standard and custom sizes with various coatings and design components for use in different applications. Additionally, sealed manhole systems are available, which can be built to specification. Access and service manholes are versatile access points to various equipment and pipe connections. These manholes are strong enough for traffic applications, including in roadways, parking lots, and pedestrian paths.
