Estudio geotécnico in Castellar del Vallès

In Castellar del Vallès, formations of sandstone, conglomerates and flysch predominate, occasionally accompanied by compact gravels, slates, limestones and igneous rocks. These strata normally provide a good bearing capacity, suitable for conventional foundations, although the overall low permeability may influence the ground’s hydrological behaviour and condition drainage on the plot during the construction phase and the building’s service life.

Seismic activity in this municipality is very low, with only two events in 30 years and a low maximum magnitude (Mmax 2.6); therefore, seismicity does not constitute a relevant constraint. The non-clayey substratum rules out risks associated with expansive soils. However, given the occasional presence of limestones and dolomites, it is essential to verify the possible existence of karstic cavities before carrying out any foundation, as this is the main constraint for the geotechnical study in the area.
