Estudio geotécnico in Altafulla

In Altafulla, limestone, dolomite and marble formations predominate; these rock materials generally provide a high bearing capacity for shallow and deep foundations. The areas of fine sands and silts, which are present in smaller proportions, require special attention due to their greater compressibility and lower strength, whereas gravel and compact sands, although they are only found occasionally, offer good conditions for foundation construction. Permeability is low at the surface, although significant aquifers may exist at depth, which should be taken into account when designing foundations.

Seismic activity in Altafulla is very low, with few records and low magnitudes (Mmax 1.7), so seismicity does not represent a relevant constraint for structural design. The non-clayey substrate rules out the presence of problems associated with expansive soils, thereby facilitating the geotechnical design. In this context, the main aspect to control is the possible local presence of fine materials, which may affect the uniformity of bearing capacity in certain areas.
