Geotechnical study in Búger

In Búger, soils formed by fine sands and silts predominate, accounting for more than 96% of the geotechnical substrate, offering an intermediate bearing capacity and generally sufficient for most shallow foundations. Sandstone, conglomerate and flysch formations are rare in the area. Given the low permeability of these formations, water may accumulate in shallow aquifers, which advises carefully assessing the water table level and the possible impact on foundation stability when preparing the geotechnical study.

The municipality shows moderate seismicity, with 24 recorded events over a period of 30 years and a maximum magnitude of 3.2, which is insufficient to require strict seismic design requirements, but is relevant for the overall risk assessment. The absence of an clayey substrate eliminates the risk of expansivity in the area, allowing for more conventional foundation solutions. However, the potential presence of karst phenomena in the ground makes it essential to check for them explicitly before executing any foundation, since this factor can condition safety and durability of the works in a significantly relevant manner.
