Dome Technology to construct fly-ash storage dome for repeat customer Boral Material Technologies
Boral Material Technologies (BMT) has contracted with Dome Technology to build a fly-ash storage DomeSilo™ near Cartersville, Georgia, an inland site northeast of Atlanta.
This is the third Dome Technology project for BMT. Construction began the first week of August 2016 with a projected completion for Dome Technology’s scope of work by spring of 2017.
According to Dome Technology sales manager Lane Roberts, BMT was seeking to maximize storage on limited land and to secure an economical storage solution. BMT’s director of engineering services Gary Gentry agrees. A dome would provide the amount of storage needed to meet operational needs, allowing Boral to “maximize storage for the footprint at a cost that’s susceptible to return on capital investment,” he said.
The site is comprised of karst, where water has dissolved portions of the limestone and left voids in the rock; this can result in sinkholes and unsure foundations. Based on front-end engineering, Dome Technology’s team identified the ideal foundation type for this concrete-reinforced structure.
“We looked at different kinds of deep foundations, and (BMT) agreed that micropiles were the only kind that would work,” Roberts said.
The micropiles’ thinner shafts allow them to penetrate limestone and better shore up the foundation. Because of their thinner diameter, a greater number of piles will be installed to provide sufficient support.
In 1997 Dome Technology built a 30,000 metric ton fly-ash dome for the company in Walnut Cove, North Carolina, and in 1998 Dome Technology built an 8,839 metric ton dome in Fontana, California.
According to Gentry, Boral is a repeat customer based on the experience working with Dome Technology in the past and “because of the professionalism and success of the previous two projects.”
