Estudio geotécnico in Ólvega

In Ólvega, hard materials predominate, such as sandstones, conglomerates and flysch, followed by compact gravels and sands, along with the occasional presence of limestones, dolomites and marbles. These types of ground generally provide a solid foundation with good bearing capacity for supporting shallow and deep foundations, although permeability is low and shallow aquifers may exist in certain areas. The choice of foundation technique requires considering the compaction and the local heterogeneity of these strata.

Seismicity in Ólvega is considered moderate, with 16 events in the last 30 years and a maximum magnitude of 3.5, which implies a low seismic risk, without significant impact on conventional structural design. The substratum is not clayey, ruling out expansivity problems for the foundation. Nevertheless, the possible existence of karst phenomena in limestones and dolomites makes it necessary to carry out a detailed check prior to construction, this being the main geotechnical constraint to analyse in the study phase.
