The seismic retrofit and structural consolidation of the walls of Chiari Hospital were accomplished using Ruregold's CRM reinforced plaster and Leca lightweight solutions. In the historic wing of the hospital, the walls were reinforced with Ruregold's CRM Reinforced Plaster, while the light seismic consolidation of the floors utilized Leca solutions.

The complex, composed of structures from different periods, exhibited signs of deterioration and required seismic upgrades to its oldest parts, along with reinforcement of some masonry works. To preserve the existing floor types and reduce structural weight, the Leca-CentroStorico light seismic consolidation system was chosen for the horizontal structures. This was complemented by the Ruregold CRM Reinforced Plaster System for strengthening the wall partitions.

Structural Restoration of the Masonry

The Ruregold CRM Reinforced Plaster system, used to restore the structural integrity of the masonry, enhances strength and ductility parameters. The solution includes G-MESH 400 and G-MESH 490 meshes combined with Helical Connectors, stainless steel bars, or G-Mesh Connectors—preformed "L" connectors made of alkali-resistant fiberglass. Additional components include the G-Mesh Handkerchief for stress distribution at connection points and the G-Mesh Angular for corners.

The system is completed with MX-RW High Performance structural mortars, which are based on high-pozzolanity hydraulic binders, MX-CP Lime based on pure natural lime NHL 3.5, and MX-15 Cement-based fiber-reinforced plaster. Together, these create an ideal CRM system for the consolidation and structural reinforcement of existing brick and irregular stone walls.
