Conference Theme
Deep Mixing 2021 – Best Practice and Legacy

Leaders in the international deep mixing community are pleased to present this 7th conference in a series on deep mixing.

Deep mixing construction activity has increased markedly in many parts of the world, and the mixing technology has attained a permanent place in modern geotechnics, offering flexibility and competitive solutions of ground improvement and foundation engineering. Important advances in materials, equipment, process control, design, research and project delivery mechanisms have occurred since Deep Mixing 2015, held in San Francisco. Deep Mixing 2021 will provide a forum for international exchange of this new information. The technical program will include presentations on all aspects of current soil mixing technology, including contemporary research and lessons learned, and will provide a forum for discussion with all stakeholders (authorities, clients, contractors, consultants, researchers, equipment manufacturers and binder suppliers). Deep Mixing 2021 will also focus on defining the future of deep mixing and transferring the charge of advancing the industry to the next generation of practitioners, passing the torch.

Who Should Attend

Deep Mixing 2021 will gather design professionals, geotechnical and environmental engineers, contractors, researchers, material and equipment suppliers, and government agencies involved in the design and construction of deep mixing applications for foundation and excavation support, liquefaction mitigation, seepage control, and environmental stabilization.

Program Overview

Morning plenary sessions will include comprehensive keynote lectures presented by invited renowned international deep mixing specialists and a special presentation on a current major deep mixing project. The lectures will overview practices and the diversity of soil mixing applications in leading markets, with a focus on regional differences, lessons learned and future trends. Lectures will be devoted to deep mixing design and contracting strategies, properties and testing of stabilised soil, recent research and recommendations for soil mixed walls, liquefaction mitigation and environmental considerations.

Afternoon sessions will include parallel workshops of presentations chosen from over 150 abstracts from 30+ countries, allowing a wider forum of presenters and a deeper dive for participants into selected aspects of deep mixing, focusing on material properties, field performance, mixing equipment and installation process, modeling and design methods, quality control and quality assurance, environmental soil mixing, and lessons learned.

Plenary discussions will be held daily after the keynote lectures as forums for adding to the content and sharing ideas on how to advance practice.
