New Guide Covers Drilled Shaft, Diaphragm Wall Tremie Concrete Placement
The Deep Foundations Institute (DFI) and the European Federation of Foundation Contractors (EFFC) have released a free download of the recently published “Best Practice Guide to Tremie Concrete for Deep Foundations.”
The primary purpose of the “Best Practice Guide to Tremie Concrete for Deep Foundations” 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.
