Estudio geotécnico in Santiponce

In Santiponce, the dominant strata are composed of limestones, dolomites and marbles, with a significant presence of gravel and compact sands, as well as areas of water mass and layers of fine sands and silts. These materials, mostly of a stony and granular nature, provide the ground with good bearing capacity, allowing direct foundations on bedrock or competent soils in most cases. However, the occasional distribution of fine sands and silts must be assessed in detail, as they could present local variations in strength or compactness.

Seismic activity in Santiponce is very low, with only one recorded event in the last 30 years and a low maximum magnitude (Mmax 1.7), which minimises the seismic influence on structural designs. No risks related to karstification or significant expansiveness are identified, as the clays present do not show problematic expansive behaviour and the non-clayey matrix contributes to the overall stability of the strata. Therefore, the main technical limiting factor will be the local heterogeneity of the materials, especially when in contact with saturated or fine-grained zones.
