Sils is an emblematic town in the Selva region situated at the center of its tectonic depression, renowned for the historic Estany de Sils, which was once Catalonia's largest natural freshwater wetland and lake prior to its drainage in the 18th and 19th centuries. Its traditional town core is centered around the church of Santa Maria de Sils (12th-century origins, rebuilt in the 18th century with a neoclassical belfry and baroque architectural features), Plaça de Sant Marc, Carrer Major, Carrer d'Espanya, and Carrer de la Vallcanera, marked by period stone terraced houses, timber-beam ceilings, legacy lead water pipes, and galvanized iron distribution pipes heavily corroded and obstructed by scale. The municipal territory encompasses historic rural settlements of notable antiquity, including Vallcanera (featuring the Romanesque church of Santa Eulàlia de Vallcanera, 10th–12th centuries, and dispersed stone farmsteads) and the historic coaching hamlet of Les Mallorquines on the old Royal Road connecting Barcelona and Girona. Protecting structural architectural integrity across Sils, our specialists carry out trenchless leak assessments: specialized non-destructive leak detection instruments minimizing unnecessary wall and floor drilling.
Municipal water dynamics feature an elevated limescale content of 26-34 ºfH, leading to scaling in heat exchangers, while communal buildings with older asbestos-cement downpipes experience frequent grease and detergent clogs. Our mobile troubleshooting unit arrives within 15-20 minutes via the direct link of AP-7. Resolving stubborn pipe and chamber blockages, we apply tempered steel flexible mechanical snakes alongside 200-bar rotary nozzles to clear vertical stacks and chambers, and for urgent power issues our technicians ensure electrical reliability deploying harmonic-immune 30 mA residual breakers under REBT standards.
