Geotechnical study in Massamagrell

In Massamagrell, fine sands and silts predominate as soil materials, accompanied in relevant proportions by gravel and compacted sands. These soils are usually characterised by good drainage capacity and an adequate bearing capacity, enabling the use of conventional foundation solutions. Expansive clays occur only occasionally, so they do not represent a generalised risk. The presence of extensive aquifers and highly permeable soils can influence the control of the groundwater level during the excavation and foundation phases.

As for additional geotechnical constraints, seismicity is moderate, with 27 events in the last 30 years, although magnitudes do not exceed 3.4, which represents a low risk for structural design. It is important to highlight that the subsoil is not predominantly clayey, eliminating concern about expansivity in most of the municipality. However, the area is susceptible to the development of karst phenomena, so it is essential to carry out prior investigation to rule out the presence of cavities before designing and constructing any foundations. The main aspect to consider in Massamagrell for a geotechnical study is the possible existence of karst and the management of aquifers during excavations.
