Geotechnical study in Retaining walls

In Muros, the ground is formed mainly by sandstones, conglomerates and flysch, which provides a base with good mechanical response and an adequate bearing capacity for shallow foundations. The occasional presence of slates and schists may require a specific study in localised areas, but in general the dominant soils allow conventional foundation solutions, due to the low presence of compressible materials such as fine sands and silts.

The seismic activity recorded in this municipality is moderate, with 16 events over 30 years and a maximum magnitude of 3.1, which implies that it is not a factor of particular relevance in the structural design of buildings. The absence of expansive clays removes the risk of problems associated with expansivity, and there is also no karst development in the area. Thus, the most relevant constraint will be the local characteristics of the rock materials, which are fundamental for defining the appropriate foundation type.
