Estudio geotécnico in Puerto de la Cruz

In Puerto de la Cruz, sandstone, conglomerates and flysch predominate, comprising more than 94% of the substrate, providing soils that are mostly granular and of competent behaviour. These lithologies generally make it possible to achieve a good bearing capacity, allowing the design of conventional shallow foundations. The presence of permeable formations and perched aquifers implies that the groundwater table level must be analysed in detail during the geotechnical study stage, as it could influence the type and depth of the recommended foundation.

As regards seismic hazard, the area shows very low activity (5 events in the last 30 years, Mmax 3.3), so seismicity does not represent a relevant constraint for structural design. There are no signs of karstification or expansiveness problems in the predominant soils. Therefore, the main factor requiring attention will be the hydrogeological assessment associated with the presence of aquifers and the heterogeneity of the sedimentary materials at the surface.
