Estudio geotécnico in Montijo

In Montijo, soils formed by compacted gravels and sands predominate, followed by sandstones, conglomerates and flysch, which ensures good performance in terms of bearing capacity across most of the municipal district. There are also some layers of fine sands, silts and clays, but their presence is sporadic and is usually localised to specific areas. Thanks to the compact and stable composition of these materials, shallow foundations are generally feasible and stable, requiring only spot checks in those areas where finer clays or silts may occur.

Seismic activity in the municipality is very low, with only 6 events in the last 30 years and a maximum magnitude of 2.8, so it does not pose a significant design requirement for structures. The analysis of expansivity concludes that the non-clayey subsoil rules out the occurrence of problems linked to swelling or volumetric shrinkage. In summary, the main geotechnical constraint in Montijo is related to the localised presence of softer materials, with the overall set of factors being highly favourable for the foundation of new buildings.
