About

Ground improvement solutions are often considered to be of little or no use for heavily loaded structures because of their perceived inability to limit total and differential settlement to acceptable levels. Undoubtedly, the predominant use of piles for foundations of heavily loaded structures is sensible and has a long tradition. However, there are a number of applications where piling and ground improvement solutions can actually overlap and compete. It is shown that well-designed ground improvement schemes can effectively replace conventional piling solutions for a wide range of applications involving heavy loads and settlement-sensitive structures. This is achieved without compromising strict design criteria. The 11 case studies presented illustrate the use of five ground improvement methods: deep vibro-compaction, dynamic compaction, vibro-replacement (stone columns), wet deep soil mixing and jet grouting. These methods have been used in a variety of projects and soil conditions, individually or in combination. Benefits in terms of reducing construction costs, construction time and CO2 emissions are discussed where applicable. Close co-operation and understanding between geotechnical and structural engineers are required to achieve common goals. It is expected that the role of unconventional ground improvement solutions in civil engineering practice will increase in the future, providing new and interesting opportunities for researchers, geotechnical designers and specialist contractors.

Prof Michal Topolnicki, Senior Technical Advisor and Professor Emeritus at Gdansk University of Technology, retired Keller Director for Large Projects

Professor Michał Topolnicki is a distinguished expert in ground engineering and ground improvement. He earned his degree from the Faculty of Hydro-Engineering at the Gdańsk University of Technology in 1974, followed by a PhD from the same institution in 1982. From 1982 to 1987, he served as a research fellow at the Institute of Soil and Rock Mechanics in Karlsruhe, Germany, contributing to advancements in the field. Returning to Poland, Professor Topolnicki held key academic leadership roles at TU Gdańsk, serving as Vice-Dean and Dean of the Faculty of Hydro-Engineering between 1990 and 1996, and later as Head of the Marine Civil Engineering Department from 2002 to 2007. His expertise extended into industry when he joined Keller in 1996, where he played a pivotal role in the development of Keller Poland. His leadership continued as North-East Europe Manager from 2007 to 2013 and as Director for Large Projects from 2013 to 2015. Following his retirement, Professor Topolnicki remained active in academia and industry, serving as a senior technical advisor and professor emeritus at his alma mater. An accomplished author and researcher, he has co-authored four books and published approximately 200 scientific papers. Since 1989, he has been a professional engineer, designing and consulting on numerous geotechnical projects in Poland and internationally. Professor Topolnicki has also made significant contributions to the global geotechnical community. He co-chaired two international conferences on Deep Mixing in 2021 and 2024 and delivered ISSMGE TC-211’s prestigious 4th Louis Menard Lecture.
