Estudio geotécnico in Montillana

In Montillana, soils of calcareous, dolomitic nature and marbles predominate, accounting for 63,78% of the substratum. This type of lithology has a high bearing capacity, suitable for shallow and deep foundations, provided that the continuity and competence of the rock mass are confirmed. Fine sands and silts, as well as the occasional presence of sandstones and flysch, may be found in certain areas and require a site-specific assessment, as granular materials can locally affect the stability and uniformity of the support.

Seismicity in Montillana is very low, with fewer than 10 events over 30 years and a maximum magnitude of less than 4.0, so no relevant seismic requirements are expected in the design of the structures. However, the presence of karstification in the carbonate materials requires careful prior verification before any foundation, given the possible existence of cavities and dissolutions that may affect stability. The absence of clays rules out expansive risks, with karst being the main geotechnical condition to take into account during the planning of the work.
