Domeshells uses air-forms as one of the methods for building domes.
An air form is made from reinforced PVC fabric that is fabricated into the shape of the structure so that, when the air form is fixed around the perimeter of the dome slab and inflated, it forms a rigid surface on which to apply render or shot-crete.
