Estudio geotécnico in Arbúcies

In the municipality of Arbúcies, the geotechnical substrate is dominated by igneous formations such as granite and gneiss, which cover approximately 87.5% of the area, accompanied in places by compact gravels and sands. These lithologies provide a high bearing capacity, favouring conventional shallow foundations on sound rock where it outcrops, whereas in sectors with sandy or gravelly deposits it will be important to verify homogeneity and compaction in order to define the most appropriate support solution.

Seismic activity in the area is moderate, with 15 recorded events in the last 30 years and a maximum magnitude of 3.2, values that indicate a low seismic risk. The absence of expansive clays rules out potential ground-heave problems. There is also no risk of karstification according to the available data. Therefore, the main geotechnical consideration focuses on the local lithological variability of the soils for the correct selection of the foundation system.
