Estudio geotécnico in Barxeta

In Barxeta, the dominant substrate is mainly composed of limestones, dolomites and marbles, together with compact gravels and sands, which generally provides good bearing-capacity conditions. The occasional presence of gypsum, anhydrite and salts poses a dissolution risk that must be assessed, while clays and peats, although rare, are not recommended as a support level for foundations. The formations, for the most part impermeable or of low permeability, may influence the management of groundwater during construction.

Seismicity in Barxeta is very low, with only 3 recorded events over 30 years and a maximum magnitude of 2, which minimises the need to consider special measures in structural design due to this factor. Karst is a relevant feature in the municipality and must be thoroughly verified before carrying out any foundation due to the risk of cavities. The absence of clayey soils rules out expansivity problems, so the karstic formation is the main geotechnical constraint to be taken into account in studies and works.
