Estudio geotécnico in Polopos

In the municipality of Polopos, slate and schist substrates predominate; these metamorphic materials generally provide a competent foundation for footings, although they exhibit very low permeability. This feature implies that, despite their strength, there may be localised surface aquifers. For this reason, it is crucial to identify areas that are little altered in order to establish the foundation under stable conditions and with adequate bearing capacity.

Seismicity in Polopos is considered to be very low, with only five recorded events over 30 years and a low maximum magnitude of 3.1, a factor that minimises the seismic influence on structural design. As the substratum is non-clayey, the risk of expansiveness is ruled out; therefore, the main precaution focuses on avoiding fractured or altered zones of the slates during foundation works.
