Estudio geotécnico in Creixell

In Creixell, the predominant substrate consists of limestones, dolomites and marbles, together with compact gravels and sands, which provides competent soils with good bearing capacities for shallow or semi-deep foundations. However, the occasional presence of deltaic silts and peats recommends avoiding these materials as a supporting base due to their low strength. Additionally, the occurrence of gypsum, anhydrite and salts raises potential dissolution problems, which must be taken into account during geotechnical investigations prior to the design of foundations.

The seismicity in Creixell is very low, with only 6 events over 30 years and a maximum magnitude of 2.1, so it does not represent a noteworthy constraint for structural design. However, the potential development of karst processes in the carbonate substrate requires a detailed verification of the presence of cavities or sinkholes before carrying out any foundation. As it is a non-clayey substrate, the risk of expansivity is ruled out, with control of the karst being the main geotechnical constraint in the area.
