Estudio geotécnico in Olmedo

In Olmedo, the most common substrate consists of compacted gravels and sands, which offer a high bearing capacity, facilitating shallow direct foundations in most locations. Added to this are less frequent associations of sandstones, conglomerates and flysch, which also exhibit good characteristics for supporting structures. The sporadic presence of limestones, dolomites and marbles may influence conditions locally, requiring a detailed assessment if works are to be carried out on these materials. Soil permeability is generally high, favouring infiltration and limiting drainage problems beneath foundations.

From a seismic standpoint, Olmedo experiences high levels of activity, with 200 events over 30 years and a maximum magnitude of 4.7, which means the seismic effect must be taken into account in calculations and in architectural design. In addition, the existence of karst-related processes in connection with the limestones makes it necessary to verify any possible cavities or instabilities before carrying out any foundation. Although there are expansive clays, these occur only in subordinate situations or in areas with no appreciable water deficit, moderating the risk of expansivity. The main geotechnical constraint for Olmedo is the combination of seismic activity and possible risks associated with karst.
