Josep builds vaults for staircases and domes as well as Catalan timbrel vaults with any surface area (rectangular, square or rounded) and in various combinations. He also does restorations and decoration work.

Vaults can be rendered with fine or rough plaster or left as bare brick.… They are built “by eye” without falsework or supporting form, cantilevered with parallel-bonded brickwork from the springing wall.

The process of building vaulted stairs involves previously measuring and marking out the site with a rallat outline drawing of the steps on the supporting wall, setting out the vault with flexible sarjo rods taking as a reference the variable measurements of the thickness of the turn and the space for the subsequent building of steps. Refurbishment work and domes involve the use of guide lines with a wooden framework giving form to the intended structure. Finally a first layer of bricks is laid with plaster and then a second one overlaid with mortar.

Typical builder’s tools are used: rules or tapes, pencils, levels, brick trowels, cleaning spatulas, mattocks, mallets, pointers, bolsters, and other hand tools as required. Also needed is a basket for mixing gypsum plaster, a mortar tray and other containers such as troughs as well as hoes and the like, and naturally the scaffolding required for building.
