Estudio geotécnico in Busturia

In Busturia, the geological substrate is represented for the most part by sandstones, conglomerates and flysch formations, complemented to a lesser extent by limestones, dolomites and marbles. These lithologies are typically competent and show good bearing capacity, which allows conventional foundation solutions to be considered for much of the municipality. However, the secondary presence of fine sands and silts may require a specific assessment to rule out possible areas of lower resistance.

Seismicity in Busturia is very low, with only one recorded event over 30 years and a maximum magnitude of 1.9, so it does not constitute a significant constraint for structural design. Nevertheless, due to the presence of carbonate rocks such as limestones and dolomites, the risk of karstification must be carefully verified before defining the foundation solution, as there could be instability due to underground cavities. The main geotechnical constraint in the area lies in the potential for karst, which requires a thorough prior geotechnical study to ensure the safety of the planned works.
