Estudio geotécnico in Macotera

In Macotera, the subsoil is dominated by compacted gravels and sands—materials that represent almost 55% of the surface and provide excellent bearing capacity for shallow foundations, thanks to their high strength and low compressibility. Sandstones, conglomerates and flysch are also common, contributing additional stability and enabling conventional foundations without major complications. The occasional presence of slates, schists and bodies of water is in the minority and usually does not condition the designs, except in very localised areas. The high permeability of the subsoil, due to these extensive and productive aquifers, promotes efficient drainage but requires studying the groundwater table before excavating in order to found the structure.

Seismic activity in Macotera is very low, with only one recorded event every 30 years and a very low maximum magnitude (Mmax 2.2), so seismicity does not influence foundation design strategies. The risk of expansiveness is low, as expansive clays are subordinate or are found in climatic zones with low activity; nevertheless, it is recommended to identify them locally to rule out differential settlement. Overall, the main technical consideration in the geotechnical study of Macotera is the characterisation of the groundwater table, given the substantial permeability of the ground.
