Estudio geotécnico in Welcome

In Bienvenida, the ground is mainly dominated by phyllites and schists, metamorphic materials that usually exhibit good strength and low compressibility, which favours the bearing capacity for shallow or semi-deep foundations. Locally, secondary layers of overconsolidated clays and marls may be found, although their compactness limits mechanical risks, while compact gravels and sands or outcrops of granite and gneiss appear only in specific areas, further enhancing the stability of the substrate to support buildings.

The seismicity in the municipality is considered very low, with a single low-magnitude event (Mmax 1.8) recorded over 30 years. However, since there is a risk of karstification, it is essential to carry out a specific geotechnical study to rule out the presence of subsurface voids before defining the structural foundation, as they could compromise the ground’s stability. The absence of clayey soil rules out expansivity-related problems, so the main geotechnical constraint in Bienvenida will be the thorough verification of any possible karst processes.
