Estudio geotécnico in Casalarreina

In Casalarreina, the predominant geotechnical substrate is mainly composed of fine sands and silts, followed by compacted gravels and sands, which provides generally favourable conditions for the ground bearing capacity. The occasional presence of water bodies requires attention in specific areas; it is advisable to avoid founding directly on them due to the potential variability in strength and possible differential settlements. Although the formations show low permeability at the surface, they may contain aquifers at greater depth, so groundwater level studies are particularly recommended before defining the foundation type.

Seismicity in the municipality is very low, with a low recurrence of events and limited magnitudes (Mmax 2), so it does not represent a relevant constraint in structural design. The analysis of expansiveness confirms that the substrate is not clayey, virtually eliminating the risk associated with expansive soils. In this way, the main variable to control in Casalarreina consists of carefully identifying areas affected by surface or groundwater during the geotechnical study prior to construction.
