Bruce is a chartered engineer and fellow of the Institution
of Civil Engineers (U.K.), and a licensed professional geologist
and engineering geologist in the U.S. He has published over
350 technical papers and coauthored 3 textbooks. He is an
active member of many professional societies, including
ASCE, ADSC, DFI, USSD, ASDSO, AEG and ISM. Bruce has
received the Kapp, Baker and Terzaghi awards from ASCE. He
was the ISM's 2009 Lizzi Lecturer and USSD's 2019 Legacy
Lecturer. He has also co-organized international conferences
on Grouting and Deep Mixing (1992, 2003, 2017 and 2022) and
on Quality in Construction (2005). He holds degrees in
geology and geotechnical engineering from Aberdeen
University, Scotland.
George Burke, P.E., D.GE, worked for over 30 years for
Hayward Baker, a Keller Company. He was the senior vice
president - engineering for 20 of those years, and previously
served as vice president of Hayward Baker Environmental,
manager of Hayward Baker's Jet Grouting Division, and
project engineer for Special Projects. Burke is widely
recognized for his contributions toward the development,
design and application of jet grouting and mechanical soil
mixing in North America.
He is a member of DFI and ASCE and was active on the
ACSE Grouting Committee when it developed the first jet
grouting guidelines, as well as on DFI's Soil Mixing
Committee. In 2009, he was confirmed as a diplomate of the
Academy of Geo-Professionals, followed by receiving the
2010 Wallace Hayward Baker Award from the Geo-Institute
of ASCE for the development of jet grouting and soil mixing
technologies. He also received the 2017 Distinguished
Service Award from DFI for his contributions to the deep
foundations industry.
Burke delivered a keynote presentation at the DFI-ICOG
2012 International Conference on Grouting and Deep
Mixing, and in 2013, he co-authored the Jet Grouting
chapter of the third edition of Ground Improvement, edited by
Kirsch and Bell. Burke received bachelor's and master's
degrees in civil (geotechnical) engineering from Drexel
University.
Raffaella Granata has been with Trevi - Italy since 2004
as technical advisor at the Design, Research & Development
Department. Before joining Trevi, she worked for Rodio and
was responsible for their geotechnical laboratory, where she
studied the performances and behaviors of grout mixes and
developed new formulations and types of mixes. Over the
past 35 years, she has been involved with constructiondesign
and technical supervision for a number of projects
around the world, including tunnels, dams and levees, and
confinement of polluted areas.
Typically, the G.R.E.A.T.S. Award is not a
posthumous award. An exception has been
made in this case considering that Kettle was
part of the conference organization since the
beginning, and the organizing committee
decided to honor him in this way.
Clif Kettle, B.Sc., FGS, had more than
45 years of grouting experience starting
with Colcrete (U.K.) in 1975, and then
Soletanche Bachy, where he became
group lead specialist for ground treat-ment. Based in the U.K.,
he focused mainly on rock grouting for dams and
compensation grouting. Kettle worked in more than 30
countries and was involved in major grouting works in soil
and rocks, tunnels, anchors and micropiles. He also had
significant experience with well drilling and monitoring, and
instrumentation.
Kettle was the 2018 recipient of the British Geotechnical
Association (BGA) John Mitchell Award and was an active
participant in the Grouting Fundamentals Course in the U.S.
and grouting committees in North America.

He was also co-author of the publication Grouting for
reservoir dams - A guide to good practice, 2018 for the Construction
Industry Research and Information Association (CIRIA, U.K.).

Granata is the co-chair of DFI's International Grouting
Committee, a member of the EFFC-DFI task groups on tremie
concrete and support fluids for deep foundations, as well as
the author or co-author of more than 50 technical papers.
Granata graduated from the University of Milan, Italy, with a
specialization in geotechnique and hydrogeology.
Dr. Håkan Stille, professor emeritus in soil and rock
mechanics at the Royal Institute of Technology (KTH) in
Stockholm, has worked extensively in industry and academia.
He has also been involved in geotechnical engineering
work throughout the world for more than 40 years. Many of the
projects have involved rock tunnels and dams exposed to the
adverse effects of water flow and changes in water pressure,
where rock grouting has been a challenge. During the last 10
years, he has also been involved in revising the Eurocode as an
expert in rock engineering and risk management.
Stille has supervised more than 30 Ph.D. students, of whom
10 have studied rock grouting from different perspectives. To
date, this work has resulted in some 50 papers in peerreviewed
international journals. He has written two
international textbooks, Rock Engineering, together with Arild
Palmstrom, and Rock Grouting - Theories and Applications.
