Estudio geotécnico in La Garrovilla

In La Garrovilla, compact gravel and sand predominate, followed by fine sands, silts and, in smaller proportions, slates and schists. The granular nature of these soils provides a good bearing capacity, which favours the adoption of conventional shallow foundations in most projects. Low near-surface permeability is characteristic of the area, although it is possible to find relevant aquifers at depth; this is an important aspect for controlling the groundwater level during the construction phase.

With regard to seismicity, the municipality shows significant activity with 52 events over the last 30 years, although with a maximum recorded magnitude of 4.4; therefore, the structural design must give particular attention to the effects of moderate-level seismicity. The absence of karst and the predominance of non-clayey substrates rule out risks associated with both dissolution and expansive soils, positioning seismicity as the main geotechnical constraint to manage in the pre-construction studies and the design of the structures.
