The Anchor Monocast Box Manhole

Anchor Concrete's monocast Box Manholes are a value-added alternative to large diameter manholes. Anchor's unique joint design allows our monolithic structure to be easily installed at the springline of large pipe and culvert. In addition to fewer joints to seal and less handling time, our Box Manholes are lighter and more economical than large diameter manholes. Anchor means value-added solutions to your large diameter pipe connections, but you won't really know how easy and cost effective they are until your crew installs one!
