Estudio geotécnico in Martorell

In Martorell, fine sands and silts predominate, followed by gravels, compact sands, and in smaller proportions sandstones, conglomerates and flysch. These materials generally show an adequate bearing capacity for building, especially where gravels and compact sands crop out. Nevertheless, in areas with silts or where slate and schist are present, it may be necessary to carry out a careful analysis of the mechanical behaviour and the depth of founding, in order to optimise the foundation type and avoid differential settlements, although the substrate does not present significant risks of expansivity.

The area is characterised by very low seismicity, with only one relevant event and a low maximum magnitude, ruling out this factor as an important structural constraint in the geotechnical study. There are also no signs of karstification or phenomena associated with potentially problematic soils such as expansive clays; the non-clayey substrate likewise eliminates the risk of expansivity. The main constraint in Martorell will therefore be the distribution of granular materials and the possible presence of silts—points that must be verified by means of a specific geotechnical study for each site.
