Estudio geotécnico in San Bartolomé de la Torre

In San Bartolomé de la Torre, the subsurface is predominantly made up of slate and schist, which account for more than 76% of the surface and are known for their high compactness and laminated structure. This type of ground, together with the occasional presence of limestones, dolomites and marbles, generally provides moderate bearing capacities, although the impermeability inherent to slates may require careful drainage analysis to prevent water accumulation beneath foundations. Fine sands and silts appear only very sporadically and do not usually represent the optimum support level for structures.

Seismicity in the area is very low, with an extremely small number of events and a low maximum magnitude (Mmax 2), so seismic action generally does not condition structural design in local geotechnical studies. In addition, the non-clayey substrate rules out the risk of soil expansivity, allowing conventional foundations to be proposed provided that the specific analysis of permeability and drainage advises it. Therefore, the central geotechnical constraint lies in the mechanical and drainage characteristics of the slates and schists.
