Project
Challenges
Extremely dense gravels caused refusal for screw piling techniques
Tight 1.5m corridor limited equipment size and manoeuvrability
Requirement to keep the mall operational during the day
Project
Overview
Seismic strengthening at Christchurch’s Barrington Mall required deep foundation works. Initial screw piling attempts failed in dense gravels, prompting Geovert’s engagement to deliver micropiles capable of penetrating the ground conditions. Works had to be undertaken in a narrow service corridor at night to avoid disruption to mall operations.
