Estudio geotécnico in Castilleja de la Cuesta

In Castilleja de la Cuesta, the geotechnical subsoil is composed predominantly of limestones, dolomites and marbles—carbonate materials that provide a high bearing capacity for shallow and deep foundations. The lithological structure favours the presence of local and discontinuous aquifers with moderate permeability and output, which may make it possible for groundwater levels to occur at different depths; this factor must be identified and appropriately managed in the studies carried out prior to the foundation works.

Seismicity in the municipality is very low, with only one recorded event in the last 30 years and a maximum magnitude (Mmax) of 1.7, so it does not represent a relevant constraint for structural design. Although the soil matrix may contain non-expansive or dispersed clays, the overall risk of expansivity is minimal given the non-clayey nature of the carbonate subsoil. The most significant factor to consider is the possible presence of groundwater levels, which must be verified on site in order to select the most suitable foundation type and depth.
