Because the drill bit is hollow, It drills the hole and as it is removed they pump in concrete to keep the hole from collapsing in on itself. This is common practice especially in loose soils.

Dla takich długości pali daje to lepszą gwarację jednorodności betonu bez raków. Głównie przy fundamentach mostów.

Concrete goes in before the rebar cage only when it’s the blinding layer, creating a clean, level, stable base that keeps reinforcement properly positioned and protected from direct soil contact.
