Helmut G. Kobler, P.E.
Late in 1964, while working on the construction of the Montreal Subway, a dear friend of mine, Dr. Emil Schmidt, Past President and Chairman of the Sika Chemical Corporation, asked me to write a paper for ACI dealing with my past experience in the use of dry-mix coarse-aggregate shotcrete as underground support. At that point in time, my knowledge of the subject under consideration was limited and based only upon experience gained while using the process in Venezuela, Switzerland and Austria. Since, at the time of Emil's request, very little about the material and underground shotcrete procedures was known on the North American Continent, I was indeed most eager to impart to my North American colleagues the limited knowledge I possessed about the subject. The result of my efforts became known as Paper No. 3 of ACI publication SP-14 titled "Shotcreting". A while back, Professor Parker was kind in asking me to present to you at this conference, an update of my 1966 paper.

My first experience in shotcrete was in 1966 on the Glendora Tunnel in California. At that time Shotcrete was considered by many to be one of the dark occult arts. . .Since that time, meetings such as this and the continuing exchange of information between all of you in the industry has dispelled the myths. We have a better understanding of the realities of this remarkable tool we call shotcrete. . .I would like to break my discussion of shotcrete equipment into three topics. The shotcrete machines or guns; The material delivery systems; Accessory items.
