Estudio geotécnico in La Llagosta

In La Llagosta, soils formed by fine sands and silts predominate, creating a substrate characterised by low permeability at the surface, although these formations may host more significant aquifers at a certain depth. This granulometric composition generally provides adequate bearing capacity for conventional foundations, although detailed analysis of the thickness and uniformity of the silty strata is essential to avoid differential settlement, particularly in residential or industrial developments.

Local seismicity in La Llagosta is very low, with only 5 recorded events in the last 30 years and a maximum magnitude of 1.6, which implies that seismic action does not represent a relevant constraint in structural design. The non-clayey substrate eliminates the risk associated with expansivity, facilitating geotechnical planning with fewer uncertainties. In short, the main focus should be on adequately characterising the thicknesses and continuity of the silt-sand layers, as well as on identifying the presence of any possible deep aquifers that may condition excavation and foundation works.
