Estudio geotécnico in La Ràpita

In La Ràpita, soils are predominantly formed by limestones, dolomites and marbles—rock formations characterised by high compressive strength and excellent bearing capacity. These lithologies generally allow shallow or semi-deep direct foundations, provided that the local integrity of the rock mass is verified and that there are no altered blocks. The presence of highly permeable and productive aquifers implies that any intervention must include solutions to mitigate possible water inflows during excavations and to guarantee the stability of the structures.

Seismicity in the municipality is moderate, with records of 30 events over 30 years and a maximum magnitude of 2,5, which does not represent a significant requirement from the structural design standpoint. Expansive clays occur in a subordinate manner or only in specific climatic areas, so the risk of expansivity is considered low overall. The main factor governing the geotechnical study in La Ràpita is linked to the local heterogeneity and fracturing of the carbonate rocks, together with the management of groundwater due to the high permeability of the ground.
