Preface
The information contained in this book has been collected over a 20-
year period. It came from actual experiences, letters, papers, and partial
copies of documents forwarded to me from various sources. I had many
discussions with those whom I consider to be quite knowledgeable on spe-
cific subjects that are directly related to grouting. I learned a lot from the
numerous technical conferences, seminars, and meetings I attended.
I have not written every word in this book, and it certainly is not my intent
to plagiarize anyone. There are some who will not agree with what is con-
tained within this book; some will say I' ve written too much; and others will
say I didn't put enough in this book. A lot of the material contained herein
is from copies of papers and letters that were sent to me over the years by
others. The intent of this book is to put down in writing, and in a logical
sequence of events, this collected knowledge so that it can be used as a
handy reference. The reader will soon see that it is not just a matter of pour-
ing grout under a piece of equipment but that numerous sequential steps and
procedures can make or break a grout job.
I once had a fellow tell me that he had 25 years of experience in machin-
ery grouting. After observing this individual's approach to grouting for a
few days, it was obvious that he had about three weeks of experience, recy-
cled more than 1300 times. Unlike a fine wine, improper grouting proce-
dures and techniques do not improve with age. A bad grout job is a bad
grout job no matter what you try to do to it later.
