RENOVATION OF THE FACADES AT CASA TORRENTS (CA LA BURESA)

February del 2025


This modernist building was designed around 1906 by the architect from Manresa, Ignasi Oms i Ponsa. At the time of its construction it was the most important residential building in Manresa and it remains the most iconic and popular building in the city to this day.
The work to be carried out depends on the different issues:
Manual picking of damaged, bare, or easily breakable areas of damaged stone.
Disinfection treatment by means of broad-spectrum biocides with mixed treatment of quaternary ammonium salts and demineralised water.
Spot application of solidifier based on dissolved ethylene silicate with white spirit on the clean surface.
Comprehensive cleaning of the entire wall with the projection of oxide or aluminium silicate at low pressures.
Supply and application of elastic coating based on monocomponent polyurethane with a low content of organic solvents. They boast a large absorption flexibility, resistance to the sun's rays, and can be transited while being lightweight.
Recovery of volumes, flashings, and concrete shapes equal to the original with special mortars without retraction. Previously, in order to give it body, stainless steel framework will be crafted, connected to the original stone with special stainless steel screws.
Application of a toning patina based on lime water and pigments to unify the treated areas.
Application of water-repellent coating in order to protect the stone from the action of water and external agents, with the HIDRO ES (FTB) product or a similar type, applied by brush through impregnation on the clean and dry surface.
