Going into detail, the contractors that carried out the work used masonry mortars to reconstruct portions of the facing walls, dehumidifying renders to restore masonry damaged by rising damp, high-performance renders and other technological systems to strengthen the structure of Oratory (which had been damaged by the earthquake in August 2016), chemical anchors, various materials to thermally insulate the walls, waterproofing systems for the substrates, mortars for screeds, adhesives and grouts to install the stone paving and the stone steps and, lastly, mineral-based coatings for the internal and external walls.

MAPESTONE CALCIX was used for the cobblestones outside the church, a cement-free system specific for renovating stone paving, including of historical interest. Perfect for footpaths and areas used by pedestrians and light vehicles, and compliant with Italian standard UNI 11714-1, this system is made up of two types of pre-mixed mortar: one to install the cobblestones (MAPESTONE TFB CALCIX) and the other for grouting joints (MAPESTONE PFS CALCIX). They are both natural hydraulic lime-based (NHL) products, and also contain inorganic Pozzolanic materials, selected aggregates and special additives: the result is a system that is highly sustainable and highly durable. MAPESTONE PFS CALCIX is available in either a light colour or a darker colour (Tenebris).
