Estudio geotécnico in Brozas

In the municipality of Brozas, the dominant substrates are slates and schists, covering more than 75% of the territory, followed in smaller proportions by outcrops of granite, gneiss and other igneous rocks. These materials generally exhibit very low permeability and high cohesion, which favours good stability conditions for shallow foundations using strip footings or a raft, provided that there are no significant alterations or weathered zones. The largely prevailing presence of metamorphic rocks enables a medium to high bearing capacity, facilitating the structural design of conventional buildings.

Seismic activity in Brozas is very low, with only around 4 recorded events over 30 years and a maximum magnitude of 3.5, so it does not represent a relevant constraint for structural planning. There is no risk of karstification or associated dissolution, and the non-clayey substrate rules out the presence of problems related to expansiveness. The main factor to consider in Brozas will be the control of weathering of the rock materials and the verification of the contact quality for the foundation.
