Types of ground in Alicante/Alacant
The predominant soils in Alicante are mainly composed of limestones, dolomites and marbles, as well as sandstones, conglomerates and flysch. In general, these materials offer good bearing capacity for deep foundations, although they require attention in shallow foundations due to their heterogeneity. The low permeability of these formations favours water stability, but may pose challenges in deep excavations, calling for specific studies to determine their behaviour.
The presence of limestone and marble formations, in addition to the documented karst, constitutes an important factor that must be verified before carrying out foundations. The moderate seismicity, with an Mmax of 3.4 and 52 events over 30 years, should be taken into account in structural design to ensure safety, although it does not represent a high seismic risk compared with other territories.
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:

Compact gravels and sands
High-compacity granular deposits, typically associated with old fluvial terraces (Ebro, Duero, Tajo, Guadalquivir rivers) and Pleistocene glacis. They have no cohesion (they are not clays) but their a

Gypsum, Anhydrite and Salts
Chemically formed sedimentary rocks produced by the precipitation of minerals dissolved in closed basins. Gypsum predominates (calcium sulphate) and, to a lesser extent, anhydrite and salts (halite).

Overconsolidated clays and marls (Duras)
Cohesive soils with a hard feel, sometimes with a rock-like appearance when dry (grey marls, pre-Pyrenean facies, deep Guadalquivir basin). They have a long history of geological compression in the pa
