Estudio geotécnico in Peñafiel

In Peñafiel, formations of limestones, dolomites and marbles predominate, accounting for more than half of the soils in the municipality and offering generally high bearing capacity, which allows robust direct foundation solutions to be considered. Some levels of gypsum, anhydrite and salts are common in the area; these materials can give rise to dissolution phenomena, as well as the development of underground voids and subsidence if they are not investigated properly during the geotechnical study phase. Areas with compact sands and gravels, although less frequent, also provide layers suitable for founding.

Seismic activity in Peñafiel is considered high, with a maximum relevant magnitude (Mmax 4.7) and more than 150 recorded events over 30 years, which makes it necessary to take seismicity into account in structural design. In addition, the significant presence of carbonate materials implies a potential for karst features that is essential to analyse in detail before executing any foundation, as cavities or associated instabilities may exist. In this context, the main geotechnical constraint is determined by the possible presence of karst and the dissolution of gypsum.
