Estudio geotécnico in Mazcuerras

In Mazcuerras, a substrate composed mainly of sandstones, conglomerates and flysch predominates; these materials account for close to 78% of the soils within the municipality. There is occasional presence of limestones, dolomites and marbles, as well as some deposits of fine sands and silts. The dominance of these sedimentary rocks, generally compact and little deformable, provides adequate bearing capacity for most shallow foundations; however, the naturally low permeability of the formations may require specific drainage analyses and groundwater control to avoid problems associated with the water table level or local aquifers.

In the section on geotechnical risks, seismicity in Mazcuerras is notable, with 145 recorded events over 30 years and a maximum magnitude of 4, which implies that structural design must take into account moderate seismic actions. Likewise, the presence of carbonate materials such as limestones and dolomites makes it necessary to check for karst phenomena before defining the foundation, as these may affect the stability and homogeneity of the ground. The non-clayey substrate rules out expansivity problems, so the main constraint is the potential existence of karst, especially in areas of carbonate rocks, in addition to incorporating the relevant measures against seismicity.
