A concrete manhole, also called a utility hole, cable chamber, maintenance hole, inspection chamber, access chamber or confined space, is the top opening to an underground utility vault used to house an access point for making connections or performing maintenance on underground and buried public utility and other services including sewers, telephone, electricity, storm drains and gas.
Our manholes are in use by local, county and federal government as well as by oilfield companies and private use. We stand by their strength and are available to speak about custom dimensions. Currently, we offer a full line of concrete manholes from 48” to 120” I.D. Manhole Material conforming to ASTM C-478, also cast iron manhole rings and covers. |
