Estudio geotécnico in Lardero

In Lardero, areniscas (sandstones), conglomerates and flysch predominate as the geotechnical substrate, accounting for approximately two thirds of the outcropping lithology. These materials often exhibit good bearing capacity and competent behaviour for the foundations of buildings, provided that the absence of altered strata or loose materials at depth is confirmed. Compacted gravels and sands, although occasional, may present acceptable values of bearing capacity; however, the discontinuous nature of these deposits makes prior specific investigation mandatory before placing the foundations. Water masses, which are also present in a significant proportion, must be taken into account in order to avoid foundations on saturated soils.

Seismicity in Lardero is high, with more than 150 events recorded every 30 years, so this factor requires particular attention in structural design, although the maximum magnitude observed (Mmax 4) remains within moderate values. There are no constraints related to the presence of karst. The risk of expansivity due to clays is minor, since they appear only subordinate in occurrence or in areas of low climatic impact, and are not considered a principal constraint. Accordingly, control of seismicity is the main geotechnical aspect to take into account when preparing the geotechnical study for buildings in this municipality.
