Piton très court que l'on enfonce en le forçant dans un trou préalablement creusé dans la roche compacte.

CONT

[...] une technologie issue du bâtiment : les pitons à expansion. De modèles variés, ceux-ci peuvent se placer n'importe où, puisqu'on les enfonce dans un trou creusé à l'aide d'un tamponnoir.
