Geotechnical study in Lorquí

In Lorquí, the predominant subsoil comprises compact gravels and sands, followed by formations of limestones, dolomites, and marbles, as well as a significant proportion of hard sandstone and other sedimentary rocks. These materials generally provide good conditions for bearing loads, since compact gravels and sands offer a high bearing capacity and carbonate rocks such as limestones provide adequate strength for direct foundation. However, the occasional presence of overconsolidated clays and marls may require specific checks in localised projects.

The seismic hazard in Lorquí is very low, with only 6 recorded events over 30 years and a maximum magnitude of 2.7; therefore, seismic risk does not represent a significant constraint for structural design. The analysis of expansiveness rules out risks associated with clayey soils due to the absence of problematic strata at depth. Thus, the main factor to consider in the geotechnical study will be the correct identification of the level of the granular or rock bedrock that will allow the foundation type and embedment depth to be optimised.
