Estudio geotécnico in Cànoves i Samalús

In Cànoves i Samalús, the predominant substrate is made up of sandstones, conglomerates and flysch, accounting for more than half of the local geology. This context, complemented by the presence of slates, schists and, to a lesser extent, gravels, compact sands and calcareous formations, results in conditions that are mostly favourable for shallow foundations, except locally where less compact or slaty materials may occur. Most of these materials provide good bearing capacity and stability, although permeability is low, which limits significant groundwater recharge and the natural drainage ability of the soils.

Seismic activity in the municipality is very low, with only two recorded events in the last three decades and a maximum magnitude of 2.4, ruling out the need to adopt specific measures for this reason in structural design. The non-clayey substrate eliminates any risk of expansivity, providing a stable geotechnical base. In this way, the main factor to be addressed in the geotechnical study in Cànoves i Samalús will be to accurately identify the local presence of less consistent materials to ensure an appropriate foundation.
