Estudio geotécnico in San Isidro

In San Isidro, fine sands and silts predominate, accounting for practically all the soils present in the municipality. These materials usually show a medium-to-low bearing capacity, which determines the type of foundation required, especially in building projects of greater scale. The low permeability of these formations implies that the presence of shallow aquifers must be taken into account in order to avoid saturation problems or variations in stability in the short and medium term.

Seismicity in San Isidro is notable, with 52 recorded events over the last 30 years, although the maximum recorded (Mmax 3.4) is of moderate intensity. The non-clayey substratum makes it possible to rule out risks associated with ground expansiveness, which reduces uncertainty regarding volumetric behaviour under structural loads. Thus, the main geotechnical factor in the area is the mechanical behaviour of the fine sands and silts under loads and the correct management of subsurface water during the foundation design.
