Estudio geotécnico in El Pedroso

In El Pedroso, soils formed by granite, gneiss and other igneous rocks predominate, accounting for close to 60%, together with a also significant presence of slates and schists. These lithologies form a hard substrate, with very low deformability and high bearing capacity, which favours the adoption of direct shallow foundations. The general low permeability of these materials limits problems associated with seepage, although they may host shallow aquifers in localised areas.

The municipality’s seismicity is very low, with a record of only one minor event in 30 years and a maximum magnitude of 1.7, which rules out relevant restrictions for this reason in structural design. The non-clayey substrate implies no risks from expansivity, and there are also no conditions of karstification to take into account. The main geotechnical constraint in El Pedroso is therefore the compaction of the ground and the possible local presence of shallow aquifers, which will need to be assessed on a point-by-point basis during the geotechnical study.
