Geotechnical study in Encinasola

In Encinasola, soils formed by slates and schists predominate, constituting the most common geotechnical basis, followed to a lesser extent by deltaic deposits of muds and peats, and a residual presence of granite and other igneous rocks. The dominant materials show low permeability, which limits natural drainage and favours the retention of surface water over units that are locally aquiferous. The bearing capacity of slates and schists is sufficient for medium-load buildings, although muds and peats should be avoided as a foundation level due to their poor compactness and high compressibility.

Seismicity in Encinasola is considered very low, with barely three events over three decades and a maximum magnitude of 4.2, which represents a low risk from the seismic point of view. The non-clayey bedrock removes concern regarding expansive soils, ensuring stable conditions for foundation works. The main geotechnical constraint in the area lies in identifying and avoiding areas of soft materials, such as muds and peats, to guarantee the safety and durability of the structures.
