Work underway on Titan America DomeSilo in Virginia, USA

In Chesapeake, Virginia, Dome Technology is hard at work on a 67,500-metric-ton DomeSilo for Titan America. The dome is 138 feet in diameter and 141 feet tall and is engineered to withstand settling and natural disaster alike.

It’s incredible to think that one of the strongest manmade structures in the world begins as a fabric airform, but it’s true. These images show Dome Technology’s team preparing the PVC airform for inflation. Once inflated, concrete is applied to the inside using the shotcrete method. The airform remains in place indefinitely to provide waterproofing.
