The truth is I had no idea what a geotechnical study was; I just knew the council asked for it for the project. They explained everything to us with a lot of patience (I asked a thousand questions).

Types of ground in Álava

Álava, located in the Basque Country, shows significant geological variability for geotechnical studies. The Llanada Alavesa is characterised by alluvial and clayey soils, suitable for crops but which may require specific considerations in foundations due to their expansiveness.

The Montaña Alavesa region, with its calcareous soils and more rugged terrain, may present geotechnical challenges related to slope stability. These aspects are crucial for assessing the feasibility of construction projects in the region.
