Estudio geotécnico in Pontevedra

In the municipality of Pontevedra, formations of sandstones, conglomerates and flysch predominate, accounting for 80.4% of the substrate available to support foundations. Fine sands, silts, slates and schists occur as a secondary feature. In general, these materials provide an adequate bearing capacity for conventional structures, although the low permeability of most of these rocks may influence local hydric behaviour and the management of groundwater and drainage during the execution of works.

With regard to geotechnical constraints, seismicity in Pontevedra is moderate, with 48 events recorded in the last 30 years and a maximum magnitude (Mmax) of 2.9, which represents a low seismic risk for structural design. The non-clayey substrate rules out the existence of risks associated with expansive soils, facilitating greater stability for foundations. The main geotechnical factor to consider in the area is the low permeability of the dominant materials, which requires attention to the disposal of water and possible surface accumulations.
