Estudio geotécnico in Alfamén

In Alfamén, geotechnical investigations find compact gravels and sands as the dominant soils, alongside sandstones and conglomerates, which provides a competent base for buildings, generally with good bearing capacity. Levels of fine sands and silts, although present, appear only occasionally and their influence on bearing capacity is usually secondary. Calcáreous formations, although detected only in a limited proportion, may require integrity studies due to possible dissolution, while the extent of permeable materials is low at the surface and becomes relevant only at greater depth in the case of large excavations.

Seismic activity in Alfamén is very low, with only 5 events over 30 years and a moderately high maximum magnitude, so the seismic influence on structural design is low. However, due to the presence of limestones in part of the substratum, it is essential to verify the possible occurrence of karstic phenomena before carrying out the foundation, as they may compromise long-term stability. Since the substratum does not have a clayey character, the risk of expansivity is ruled out, with the monitoring of karstic cavities being the main determining factor for a geotechnical study in the area.
