Cardona is a historic and monumental town in the Bages region, located within the valley of the Cardener River in the northern sector of the county bordering Solsonès and Berguedà, internationally famous for its extraordinary geological diapir of the Muntanya de Sal (the Salt Valley and the historic Maria Teresa / Alberto mining pits) and for the majestic fortress complex of the Castell de Cardona (founded in the 9th century, featuring the 11th-century canonical collegiate church of Sant Vicenç, the Minyona Tower, and medieval bastions) perched high at over 580 metres of altitude overlooking the river basin. The walled historic centre —centred on Plaça de la Fira, Carrer Major, Plaça del Mercat, Portal de Graells, Portal de Barcelona, and the 14th-century Gothic church of Sant Miquel— displays a maze of cobblestone alleys and aristocratic stone houses with ashlar walls, Gothic arches, and timber beams where vintage lead service pipes, cast-iron stacks, and galvanized iron branches encrusted with limescale and rust remain active. In Cardona, we prevent blind wall cutting with certified non-destructive tools: advanced non-destructive diagnostic tools to locate hidden water leaks and moisture without unnecessary wall or floor damage.
Properties face heavy limescale precipitation from 32-38 ºfH hard water across domestic heating networks, compounded by a continental climate with dense freezing fogs and frost down to -6 ºC. Our duty technicians guarantee reaching your premises within a 15 to 20-minute window via C-55. For technical cleansing of stacks and mains, our teams employ rotary scouring nozzle flushing at 200 bar and electromechanical drain snake equipment for traps and sewer branches, whereas on electrical panels our technicians fit Type A residual circuit breakers with 30 mA sensitivity and correct earth faults per REBT codes.
