Estudio geotécnico in La Pola de Gordón

In La Pola de Gordón, sandstonic substrates, conglomerates and flysch predominate, occasionally accompanied by fine sands, silts and calcareous formations such as limestones, dolomites and marbles. The occasional presence of deltaic muds and peats indicates localised areas where the ground exhibits low bearing capacity, so these layers should be avoided as a foundation base. In general, the dominant formations are compact and have low permeability, which ensures favourable conditions for most foundations, always evaluating the exact location to rule out any influence from soft soils.

Seismicity in the municipality is high, with more than 150 recorded events over three decades and an Mmax value of 4.7, which requires including seismic actions in the structural calculation and design. Given the proportion of limestones and dolomites, the possibility of karst processes must be thoroughly checked before starting any intervention, as they could affect the stability of the ground. The non-clayey substrate rules out expansivity risks, but the main conditioning factor for geotechnical studies in the area will be controlling karst and assessing the seismic response.
