Sand or Water Ballast System
This option is typically used for mobile or temporary dome applications. Your dome would be weighed down with large ballast bags filled with the required amount of sand or gravel. Our engineers have also designed an anchoring system with a large reinforced tube or bladder of water around the perimeter of the dome. These can be used for smaller domes (typically below 35,000 square feet).
This option is also typically used for mobile or temporary dome applications. Cement blocks are used on the outside perimeter of the dome to weigh it down, or some of our clients have created custom cement blocks with bolts embedded to them, to which the dome is attached. Some of our mobile "event dome" clients have used cement "bin blocks" to weigh the dome down. These are relatively inexpensive to rent or purchase in many areas.
Steel Plated Box Filled with Gravel
This custom anchoring system was developed by Broadwell engineers for a client who owned a gravel pit and wanted to use gravel in their anchoring system.
The goal of an air dome anchoring system is to create a consistent and strong anchoring force load. As shown above, this can be achieved in a variety of ways. Our team of 50+ employed engineers are the most innovative in the industry. We are constantly developing new and innovative ways to anchor our domes.
