| Basics of building with Arches, Vaults and Cupolas (SKAT) |
Varied uses
Vaults and cupolas cover spaces either with or without recourse to walls or other supporting structures. They are, however, merely structures. They become a roof-covering only if they are given a waterproof coating. Flat or slanted roofs and flooring can be easily obtained by infilling the rounded forms. Small span barrel vaults built between girders, known as vaulting cells or jack arches, can be used for flooring.
