Estudio geotécnico in Tías

In Tías, sandstones, conglomerates and flysch formations predominate, followed by granitic materials, gneisses and other igneous rocks. These strata are characterised by exhibiting good bearing capacity, which allows flexible options for shallow and deep foundations, especially over the gravels and compact sands identified in the area. The minor presence of urban anthropogenic fill requires particular caution, as its behaviour may be heterogeneous, and it is recommended to remove or improve it before founding any work.

Seismicity in Tías is very low, with only 1 event over 30 years and a recorded maximum magnitude of less than 4.5, so its influence on structural design is normally limited. There are no indications of karstification or notable problems with expansive soils in the area, and the geotechnical setting is mainly determined by the appropriate stability and strength of the competent materials. In conclusion, the most relevant aspect to consider is the local variability due to anthropogenic fill and the possibility of perched aquifers in the more permeable zones, requiring a correct assessment of groundwater conditions in the geotechnical study.
