Estudio geotécnico in Sant Celoni

In Sant Celoni, the subsoil is dominated mainly by granite, gneiss and other igneous rocks, representing 56.25% of the total, accompanied by compact gravels and sands, as well as a smaller presence of slates, schists, sandstones and conglomerates. This geological profile favours a high bearing capacity and allows direct, shallow foundation solutions in most cases, although it is essential to consider the possible presence of altered or weathered levels in the granitic areas. The formations identified show very low permeability; this affects the natural drainage of water and may require additional studies to prevent drainage problems.

The area is characterised by very low seismicity, with only 9 events over 30 years and a maximum magnitude of 2.7, which establishes a favourable context for structural design without the need for specific measures due to seismic activity. On the other hand, the analysis of expansivity rules out risks associated with clayey soils, since the predominant substrate does not contain this type of mineral. In conclusion, in Sant Celoni, the main geotechnical factor to consider will be the quality and condition of the rock mass alteration at the specific project site.
