Geotechnical study in Berlanga

In Berlanga, the dominant subsoil is made up of sandstones, conglomerates and flysch, being characterised by its high frequency and consolidation. These materials usually provide good bearing capacity for shallow foundations, although the significant presence of silts and peats of deltaic origin requires caution, since these soft soils are not suitable as a support level and can cause differential settlement. Formations of shales, schists, gravels and sands, present in smaller proportions, may locally influence the choice of foundation type, but are generally secondary to the dominant materials.

Seismic activity in Berlanga is high, with more than 150 recorded events in the last 30 years, although the maximum magnitude observed (Mmax 3.5) remains within a low range, reducing the need for severe considerations in structural design due to seismicity. There is no karst development and the non-clayey subsoil rules out risks associated with expansivity. The primary constraint to take into account is the extensive presence of silts and peats, which could limit the suitability of directly founding without a specific geotechnical study that determines safe support zones.
