Estudio geotécnico in Igualada

In Igualada, the predominant subsoil consists of white or soft expansive clays, representing approximately 75% of the soils, followed in smaller proportions by sandstones, conglomerates, flysch and a reduced percentage of gypsum, anhydrite and salts. The mechanical characteristics of these clays can limit bearing capacity and influence the choice of foundation type, requiring in many cases detailed studies to determine the appropriate depth and to anticipate possible delayed deformations. The occasional presence of gypsum and salts also implies the risk of dissolution, which can lead to subsidence, particularly for shallow or deep foundation systems if soil stability is not verified.

Seismicity in Igualada is classified as very low, with only one recorded event every 30 years and a maximum magnitude below 2, so it does not constitute a relevant factor in structural design. However, the potential development of karst phenomena due to the presence of gypsum-bearing materials requires specific checks before defining any support system. Likewise, although clay expansion is subordinate to the local climatic environment, it should be taken into account in projects sensitive to deformation. The main geotechnical constraint in Igualada is the heterogeneity of the subsoil and the possibility of problems associated with the dissolution of salts and karst processes.
