Types of ground in Aller
In the municipality of Aller, formations composed mainly of slates and schists predominate, with calcareous rocks, dolomites and marbles occurring to a lesser extent, as well as the infrequent presence of deltaic clays and peats. The low general permeability of these strata limits natural drainage and implies that any foundation must be carefully designed, since bearing capacity may vary depending on the specific location. Although clays and peats are rare, they represent an unfavourable environment for foundations and must be explicitly avoided as a support stratum.
Local seismic activity is moderate, with 10 events over 30 years and a low maximum magnitude, which scarcely affects structural design. It is worth highlighting the potential presence of karst due to outcrops of limestone and dolomite; therefore, it is essential to verify the existence of cavities or dissolution processes before any intervention. Since the subsoil is not clayey, there is no risk of expansive soils. In conclusion, checking for karst processes is the determining factor during the conduct of any geotechnical study in Aller.
Limestones, Dolomites and Marbles
karstic structures (caves, sinkholes, dolines) that pose the main geotechnical risk.

Phyllites and schists
Metamorphic rocks characterised by their foliation (parallel planes of weakness or slaty cleavage). Very common in Galicia, Asturias, the north of León, Extremadura and Sierra Morena. They are highly

Fangy clays and peats (Deltaic)
Soils from the Holocene period, unconsolidated, flowing muds, black in colour with a very strong organic component, sometimes in the form of pure rotting vegetable matter (peat bogs). The mud compress
