Estudio geotécnico in Candelaria

In Candelaria, formations of sandstone, conglomerates and flysch predominate, accounting for more than 85% of the substrates detected. These are generally competent materials, whose strength levels are favourable for shallow foundation design owing to their adequate bearing capacity. To a lesser extent, outcrops of granite, gneiss and other igneous rocks are found, which are also suitable for transferring structural loads efficiently. The presence of perched aquifers and contact zones between formations requires considering the possible influence of groundwater on the stability and behaviour of the foundations.

Seismicity in the municipality is classified as very low, with only 6 events over 30 years and a maximum recorded magnitude of less than 2, which does not imply relevant constraints for seismic-resistant design. No risk of karst or of harmful expansivity is reported in the substrates present. The main factor to consider in the geotechnical study in Candelaria is the local heterogeneity of the materials and the influence of water in the permeable formations, which demands a specific investigation of hydrological conditions prior to the execution of foundations.
