Felsnagel, Verpressanker, Spieß oder Injektionslanze im Berg- und Tunnelbau sowie bei geotechnischen Aufgabenstellungen wie Gründungen eingesetzt werden kann. Kürzlich hat DSI eine Zulassung für den Dywi Drill Hohlstab als temporärer Mikropfahl und Dauerpfahl erhalten , nach der bei dem Dauerpfahl eine Nutzungsdauer von 100 Jahren erreicht werden kann (Foto: DSI Underground).
