Estudio geotécnico in Border

In the municipality of Frontera, the dominant substrate mainly comprises sandstones, conglomerates and flysch, accounting for almost 57% of the ground materials. These soil types are characterised by a good bearing capacity, facilitating direct foundation solutions in many areas, provided that compaction is guaranteed. The marginal presence of clays and hard marls indicates that the risks associated with soft cohesive soils are very low in the area. However, the heterogeneity of the flysch may require additional studies on ground uniformity and monitoring of differential settlements.

Seismicity in Frontera is significant, with more than 150 events over 30 years and a maximum magnitude value (Mmax) of 4.6, which necessitates the strict incorporation of seismic criteria into the structural design of buildings. There are no indications of karstification or relevant risks associated with expansivity, given that the proportion of clays is minimal. The main constraint for the geotechnical study in Frontera will be the assessment of combined seismic effects, together with verification of the continuity and stability of the sandstone and flysch strata.
