Fiberglass Manholes

A Specialty Product

Details

Our Fiberglass manhole system is designed to work with fiberglass sewer pipe that is either manufactured by the centrifugally cast or filament wound methods and can be designed with gravity sewer lines that are 48” or larger in diameter. 

 A tangential vertical 48” diameter fiberglass tee is fabricated to the main line sewer pipe and extends vertically by using the manufactures pipe joint system. In-Line elbows can be built into the mainline sewer pipe to accommodate directional changes in the sewer line with the vertical manhole tees built directly into the elbow. The manhole top is constructed from structural fiberglass with the composite ring cast into the manhole top giving the owner a watertight, corrosion resistant, and hydraulically superior sewer system that will last.  

Our fiberglass manhole system has proven the test of time. Currently we have several projects with the City of High Point, NC that are utilizing our manhole system for over 30 years along with the City of Raleigh that is now 10 years strong and is still performing as it did when it was installed.
