Bored pier and beam

The primary difference between the bulk pier and beam and the bored pier and beam is the size of the piers. The bored piers are much smaller than the bulk piers. The diameter of the piers is usually 450 mm or 600 mm.

A minimum of four vertical reinforcement bars are placed in the pier with N6 ligatures at 300 mm centres. The drilling rig can penetrate to depths of 3 metres with minimal disturbance to adjoining structures. The bases of the piers are founded on good bearing soil at the appropriate depth.
