Estudio geotécnico in Calldetenes

In Calldetenes, the predominant substrate consists of expansive white or soft clays, which account for most of the ground, whereas compact gravel and sand are observed only occasionally. These clays, given their nature and variable compactness, may affect the ground’s bearing capacity and therefore require a thorough geotechnical study to size the foundation correctly, although the non-clay substrate identified rules out any significant expansivity. The overall low permeability makes adequate management of surface drainage necessary and may limit the natural infiltration of water, which is relevant to the stability of the foundations.

Seismicity in Calldetenes is very low, with just five events over 30 years and a maximum magnitude that is of little significance, meaning it does not represent a relevant constraint for structural design. However, the possible presence of karst phenomena requires precise verification through a geotechnical study prior to foundation works, as voids or dissolutions may exist that could affect ground stability and the safety of buildings. Karst control is therefore configured as the main factor to be considered before executing any foundation in the municipality.
