Estudio geotécnico in Loranca de Tajuña

In Loranca de Tajuña, the strata are predominantly formed by limestones, dolomites and marbles, accompanied in a significant proportion by masses of water and detrital materials such as sandstones, conglomerates and flysch. Compact gravels and sands also occur occasionally within the municipality. This lithostratigraphic set offers a solid bearing capacity, particularly in the consolidated areas, which makes it possible to propose shallow foundation solutions where the bedrock outcrops at a small depth. However, the occasional presence of loose materials, and possible saturation due to groundwater, may require a detailed analysis to avoid differential settlement.

Historical seismicity is very low, with only 4 events in recent decades and a low maximum magnitude (Mmax 2.1), so the seismic criterion does not represent a significant limitation for design. It is important to emphasise the potential presence of karst phenomena linked to the dominant carbonate formations; this aspect must be specifically verified before proposing any deep foundation, since cavities or dissolution processes can affect the uniformity and strength of the ground. In the absence of expansive clay soils, the main constraint in Loranca de Tajuña will be the characterisation of possible karst voids and the verification of the continuity of the competent stratum.
