Additional question to pile holes full of water

[Kiri Robbie]

In regard to my earlier question about pouring concrete into a pile hole, the concrete was poured directly from the shute of a concrete truck from the top and not pumped from the bottom up. Also, the water was rain water that included mud.

Dry placement methods shall only be carried out when the excavation is dry (< 100mm of water at the bottom of the pile bore prior to concrete placement).

Direct placement with a shute is only permitted if the concrete won't segregate by hitting the reinforcement cage. I would suggest to use a discharge pipe for dry pours (e.g. lay flat tremie or steel tube)
