‘Bored pier’ refers to a non-displacement pile formed in cohesive ground conditions where an auger and soil column may be extracted from the drilled hole without collapse, allowing reinforcement to be lowered into the hole and concrete to be pumped in to complete the pile. Where granular soils or groundwater present more challenging conditions, a steel casing may be used to support the hole and allow auger extraction without collapse. Bored pier foundation systems are typically used as foundation piles to limit settlement of the structures they support, however, the technique may also be applied to the construction of soldier piles for retaining walls. The bored pier foundation installation process involves minimal noise and vibration compared to driven pile techniques. Newcastle Piling has the specialist equipment and expertise to install bored piers across a wide range of site-specific soil, rock and groundwater conditions.
