Sandy soil, rocky soil ... what anchorage?

Soils can be classified according to the following classification (from the most loose soil to the most compact soil):

  • Classe A - Anchoring on light and soft ground (loose sands, soft clay ...)
  • Classe B - Anchoring on slightly stony and moderately consistent soils (silt, marl, clay loess ...)
  • Classe C - Anchoring on moderately stony and dense soils (gravel / coarse-grained sand mix ...)
  • Classe D - Anchoring on very stony and compact soils (heavy clay mixed with pebbles or stones)
