SANCTUARY OF MADONNINA DEL BOSCHETTO
Castel Mella, Brescia, IT, 2015
In September 2014, the priest saw, near San Giuseppe's altar, an important crack and the lowering of the floor. It was made a campaign to monitor the Sanctuary's structure. The analysis had a double objective: underline the differences with the cracking map that was done and check the status of the differential subsidence of Sanctuary's foundations. The analysis shew an evolution of the cracking map, the formation of new cracks and the enlargement of some existing crack. So it was decided to study the cracks' evolution with specific instrumentation. The need of the foundations' consolidation was demonstrated by the results obtained from the six campaigns of the survey, from September 2014 to November 2015. A specialized company made geognostic investigations with not invasive tests (Geoeletric investigations and penetrometer tests). The results of these tests, made on 25 November 2015, shew the presence of a soft soil under the foundations, with a low load bearing capacity. Considering the tests' results, the high artistic and architectural value of the building and all the possible technical solutions, it was chosen to use controlled injections of expanding resin. With this innovative technology is not necessary to excavate. The solution is less expensive and the execution requires only few days.
