Abstract
Process for the manufacture of vaults, characterized in that a molding cavity is formed by several coupled pieces and whose interior surfaces define a space corresponding to the one desired to be obtained in the vault, into which a precalculated quantity is subsequently inserted. Of a granular synthetic resin, partially pre-expanded and capable of being further expanded by application of heat, after which the molding cavity with its content is heated to a temperature sufficient to complete said expansion, so that said granules of soldering together and occupy all the molding space, adapting to the interior surfaces thereof.
