Estudio geotécnico in Tijarafe

In Tijarafe, the dominant geotechnical subsoil is mainly made up of sandstones, conglomerates and flysch, covering around 90% of the territory. These materials, combined with the very occasional presence of fine sands and silts, provide a base with bearing capacity that is generally favourable for most foundation typologies, although the lithological variability of the flysch may require detailed assessment in some areas. The permeability associated with these aquifers is considered moderate, which contributes to a lower susceptibility to problems of capillary rise and promotes controlled settlement, provided that the continuity and competence of the bearing stratum are verified.

The seismicity of Tijarafe is moderate, with 15 events recorded over 30 years and a maximum magnitude of 3, indicating a manageable level of seismic risk for construction, without special requirements for most structures. There are no significant risk factors associated with karst phenomena or with expansive clay soils. In this context, the main constraint for the geotechnical study in Tijarafe will be the appropriate characterisation of the flysch and the heterogeneity of the base materials, an essential aspect for a safe and efficient foundation design.
