Estudio geotécnico in Vila Joiosa, the/Villajoyosa

In the area of La Vila Joiosa, the presence of fine sands and silts predominates, which directly influences the bearing capacity of the ground. These materials generally present good conditions for shallow foundations due to their low compressibility and easy workability, provided that it is verified that the groundwater level and any possible particle transport do not pose problems during the construction process. In addition, the high ground permeability, favoured by extensive aquifers, allows rapid drainage, although it also increases the possibility of differential settlements if there are changes in the hydraulic loading.

From the seismic point of view, the municipality records a notable level of activity, with 52 events over 30 years and a maximum magnitude (Mmax) of 3.4. Although the reported magnitude is moderate, the frequency of events makes it advisable to carry out a specific assessment of earthquake-resistant risk for new buildings. The absence of clayey materials in the substrate rules out any concern regarding soil expansiveness. In this context, the main factor that must be considered is the ground permeability and the management of groundwater during the design and construction phase.
