Estudio geotécnico in Casas de Don Pedro

In Casas de Don Pedro, the predominant subsoil is formed by shales and schists, which account for the largest proportion of the ground. This type of material, together with occasional outcrops of sandstones, conglomerates, flysch and loose deposits such as sands and silts, determines a generally favourable bearing capacity for conventional shallow foundations, although the presence of some areas of gravels and compact sands can provide good local support conditions. It is important to take into account the low permeability of these formations, which favours overall stability but may hinder drainage, an aspect to be considered according to the project type and the groundwater level.

As for seismicity, the area shows notable seismic activity, with 52 recorded events in the last 30 years and a maximum magnitude (Mmax) of 4.4, so it is advisable to incorporate seismic safety criteria into the structural design. There are no recorded risks of karst or significant expansiveness, since the non-clayey substratum rules out the latter problem. The main constraint will be determined by stability under seismic conditions and by hydrogeological aspects related to the local presence of water bodies or shallow aquifers.
