Estudio geotécnico in Breña Alta

In Breña Alta, the dominant geological substrate is formed by sandstones, conglomerates and flysch, accounting for more than 90% of the surface. In general, these materials provide a competent bearing capacity and usually allow the execution of shallow (direct) foundations, depending on the degree of compaction and local weathering. The low proportion of granite and gneiss implies less variability in ground conditions, and groundwater bodies with moderate permeability may influence drainage management during construction.

In the case of Breña Alta, seismicity is notable because 105 events have been recorded over 30 years, with a maximum magnitude of 4.7, so this aspect must be taken into account in any structural design of foundations and buildings. There are no risks associated with karst or significant expansivity, with seismicity being the main limiting factor that must be addressed rigorously in the geotechnical study to ensure the safety of the structures.
