Dome airform fabrication and inflation
The dome takes shape
The PVC airform, custom sized based on the customers’ specifications, is bolted to the post-tensioned ring beam and inspected to ensure integrity. It is then inflated using large fans to form the dome shape and maintain inflation pressure; the fabric will remain in place indefinitely as it becomes the outer waterproofing membrane.
The dual role of the PVC airform
These air-inflated, PVC-fabric structures act as critical, load-bearing components in the construction of domes. They are strong enough to support layer upon layer of reinforced concrete, and they act as the exterior waterproofing membrane that’ll shed water for years and years.
Specialized fabrication to meet the highest standards
The airform is one of the few components not sourced locally; it is fabricated at the Dome Technology campus in a state-of-the-art facility to match precise design requirements. Our team utilizes software-driven, automated equipment to ensure our fabric components are cut and welded with the greatest precision and consistency.
The all-weather construction environment
Once attached to the ring beam and inflated, the airform creates a protected environment, allowing for construction to continue inside the dome in almost any weather conditions.
