Print Print this Article | Send to Colleague

The Deep Foundations Institute (DFI) and the European Federation of Foundation Contractors (EFFC) have released the Best Practice Guide to Tremie Concrete for Deep Foundations. The guide is the result of the initial study efforts of the joint DFI and EFFC Concrete Task Group that studied common problems in drilled shafts and diaphragm walls constructed using tremie methods. The primary purpose of the document is to present design considerations (concrete rheology, mix design, reinforcement detailing, concrete cover, etc.) and best practices for tremie concrete placement for drilled shafts and diaphragm walls that promote construction of high quality elements. In addition, the guide proposes changes to the methods used commonly to specify concrete mixes and the procedures to test them. It highlights important considerations to minimize risk related to concrete workmanship and quality, and potential conflicts between contracted parties.
