Types of ground in Lezama
In Lezama, substrates of limestones, dolomites and marbles predominate, followed by the presence of sandstones, conglomerates and flysch. These lithologies provide good bearing-capacity conditions, allowing direct foundations in most cases, provided that there are no near-surface layers of fine sands or silts, which are less frequent and may exhibit compressible behaviour. The low permeability of most materials reduces the risk of internal washout and indicates adequate stability of the substrate for structural supports.
Seismicity in Lezama is very low, with only one recorded event in the last 30 years and a maximum magnitude of 1.5, so it is not considered a relevant factor for structural design. In addition, since the substrate is non-clayey, the risk of expansiveness is ruled out in this locality. The main factor to consider will be the accurate assessment of the bearing capacity of the carbonate and detrital formations.
Limestones, Dolomites and Marbles
karstic structures (caves, sinkholes, dolines) that pose the main geotechnical risk.

Sandstones, Conglomerates and Flysch
Sedimentary rocks formed by the cementation of fragments of other pre-existing rocks. They include sandstones (cemented sand), conglomerates (cemented gravels) and the rhythmic alternation of sandston

Fine sands and silts
Fine to very fine granular soils with medium to loose compacity. Typical of floodplains and coastlines. Although they can support light buildings, they are treacherous soils linked to water processes:
