THE GROUT LINE
Overture
52
nd
episode of the Grout Line. For
this episode, no articles but some news
about our grouting industry.
The first item is about a possible new
International Grouting Committee that
the Deep Foundation Institute (DFI) is
in the process of creating. There are,
to my knowledge, several Grouting
organizations, official publications and
grouting courses already in existence
in NA and Europe, as follows (of
course not fully completed):
All excellent documents/courses but,
none of them, with the exception of
the Austrian comments document
and the Grouting Fundamentals
Course, covers in detail all aspects and
approaches in the industry for grouting
in Rock and Soil.
This is the reason that DFI is trying to
organize this International Committee
that, we hope, will help to put some
order in our industry, not necessarily
agreeing on everything. We know that
the “grouters” have very opinionated
approaches and ideas, and some good
confrontation, not necessarily physical
J
of course, can help our industry to
progress
The primary target of the DFI initia-
tive would be the preparation, using
the DFI „project fund initiative“, of
general guidelines and the following
specific documents summarizing the
different approaches and procedures
existing in the industry. It is planned
to review and summarize existing
documents/specifications used in the
worldwide grouting industry.
It is anticipated that the documents
should cover, at the minimum, the fol-
lowing aspects:
• Geotechnical investigation require-
ments
• Companies and key personnel
qualification requirements
• Possible contractual methodologies
• PIMS requirements and data integ-
rity verification
• Design (method, hole geometry
and spacing, choice of the grout-
ing type, grouting parameters, mix
design, preliminary trials etc.)
• Risk evaluation, reduction and
management
• Execution (drilling and grouting
methodologies, data recording,
quality controls, material testing,
field testing, equipment require-
ments etc.)
• Final Verifications and Acceptance
Criteria requirements
Additional specific projects will be
evaluated by the members of the Com-
mittee/Group.
The proposed Committee will include
Owners, Consultants, Contractors,
Manufacturers/Suppliers/Service Pro-
viders and Academics.
The mission of the Committee should
be to promote programs, technologies
and specifications that will insure the
quality of the work performed and the
possibility to increase Safety, Quality,
Durability and Sustainability to the
benefits of the Clients, the Stakehold-
ers, and the entire geo-foundation
industry.

and you are interested in finding out
