Estudio geotécnico in El Tiemblo

In El Tiemblo, compact substrates of granite, gneiss and other igneous rocks predominate, accounting for more than 78% of the surface area, while slate and schist have an occasional presence. These materials are characterised by a high bearing capacity and low deformability, making them favourable for shallow foundations, although it is recommended to check the homogeneity of the rock mass and the possible presence of fractures. The permeability of the ground is low, which may favour the accumulation of surface water in certain areas and should be taken into account when designing drainage in the vicinity of the foundation.

Seismicity in El Tiemblo is moderate, with 32 recorded events over the last 30 years and a maximum magnitude of 2.8, a value that does not significantly affect geotechnical design. Since the dominant bedrock is rock and is not exposed to risks associated with expansive clays, the issue of expansivity can be ruled out. In this context, the main geotechnical constraint in El Tiemblo is determined by the massive, stable nature of the rock substrate, which places the study needs on identifying the fracturing and heterogeneity of the granite and gneiss.
