Reinforcement for Bored Piles
In longer piles overlapping the reinforcements are very frequent. However, in this case aggregates can assemble at the joints and prevent concrete from flowing towards the borehole walls and result in a defective pile shaft. Over designing of steel reinforcement in a bored pile can lead to practical difficulties in constructing the pile shaft.
