Estudio geotécnico in Malpica de Tajo

In Malpica de Tajo, the predominant geological substratum consists of slates and schists, which provide a moderate bearing capacity and exhibit geomechanical characteristics that are favourable for conventional shallow foundations, provided that the absence of superficial weathering is verified. Water bodies cover a large proportion of the municipality, which implies paying special attention to the groundwater level and its possible influence on stability and settlement. The presence of gravels, compact sands and sandstones, locally, may provide optimal conditions for founding; however, in areas with limestones or dolomites it is advisable to consider their degree of fracturing and compaction.

Seismic activity in the area is very low, with only 1 registered event in 30 years and an estimated magnitude of 2.6, so it does not represent a demanding constraint for structural design. As regards expansivity, although certain subordinate expansive clays are present, their presence is not dominant and does not represent a significant risk under local climatic conditions. Therefore, control of the groundwater level and the heterogeneous nature of the materials appear as the main factors to be assessed in any geotechnical study in Malpica de Tajo.
