Drilled displacement piles are a type of augered pile, however instead of removing the material, the soil is displaced laterally into the surrounding soil resulting in a similar profiled regular shaft pile.
Keller has completed ground improvement works on one of Brisbane’s largest infrastructure projects – a scheme that promises to create an impressive entry to the city, while significantly reducing traffic congestion, improving road-user safety and boosting business development.
Sydney’s A$12 billion Metro City & Southwest extension is well underway and Keller has successfully completed a project to stabilise the rail embankment at Sydenham Station.
Queensland is set to benefit from a major economic boost, thanks to the expansion of a large zinc refinery in the state. Due for completion in 2021, the project is off to an excellent start, thanks to Keller successfully constructing the foundations ahead of schedule.
When a new highway service centre was proposed for a site overlying soft, challenging ground conditions, Keller was brought on board as the geotechnical contracting expert to design and construct a high-quality, cost-effective ground improvement solution.
Construction of the first Marriott hotel to be built in Australia for 20 years is underway in Melbourne, after Keller successfully completed foundation work on what proved to be a logistically demanding site.
Artificial ground freezing converts in situ pore water to ice through the circulation of a chilled liquid via a system of small-diameter pipes placed in drilled holes.
The Atlas pile is a unique “screw” shaped displacement pile. It is designed to take maximum advantage of all available soil capacity by displacing the soil rather than replacing it. The Atlas pile is a concrete cast in situ pile installed with new generation high torque hydraulic piling rigs.…
Impact rolling compacts the ground through the rotation of a non-circular rolling module delivering insitu compaction with significant densification and strength improvement.
