Tremie concrete enables the construction of deep foundations such as piles and diaphragm walls as it is self-compacting, can be placed under a support fluid and is resistant to segregation. As the urban landscape within New Zealand increases in density, deeper and more complex foundations are required. Show more…These deep foundations generate higher structural demands and often require much longer concrete pour times. Consequently, tremie concrete is increasingly becoming a highly engineered material with concrete additions and admixtures used to adapt the concrete to a specific application. These challenges have contributed to major construction issues overseas and the formation of an industry led consortium to develop guidance. This paper summarises tremie concrete guidance and discusses key considerations for tremie concrete in a project life cycle for a New Zealand context. A case study of concrete testing carried out on a recent project in Auckland is presented. Show less…
