Estudio geotécnico in L'Ametlla del Vallès

In L'Ametlla del Vallès, soils formed by sandstones, conglomerates and flysch predominate, characterised by high permeability and the presence of extensive, productive aquifers. These lithologies generally provide an adequate bearing capacity for shallow foundations, although it is essential to analyse the locally occurring presence of less competent strata. The ground’s high permeability means that, where basements or underground structures are anticipated, specific geometric and waterproofing techniques must be adopted to prevent seepage and ensure foundation stability.

Seismic activity in this municipality is very low, with a limited number of recorded events and a low maximum magnitude, so seismicity does not represent a relevant constraint for structural design. There are no karstic phenomena in the area, nor a dominant presence of expansive clays, although they should be monitored locally. The main geotechnical constraint for projects in L'Ametlla del Vallès lies in the management of groundwater and the correct characterisation of lithological heterogeneity.
