Symposium on Grouting: Grouting of Granular Materials

This paper is from a group of seven papers that constituted the Symposium on Grouting that was presented during the June 1960 ASCE Convention in Reno, Nev. The seven papers were published in the April 1961 Journal of the Soil Mechanics and Foundations Division. The papers constituted a significant contribution to engineering practice in the science and art of stabilizing foundations by grouting. This is a field in which there appears to be increasing interest among foundation engineers and one that is apt to become more important in the future as the need to build structures in difficult soils conditions increases. The papers in the Symposium were concerned with cement, clay, and chemical grouting of seams, cavities, and granular materials. The papers illustrated (1) the increased use of chemicals for grouting purposes and, in addition, their use with more conventional grouting materials such as clay and cement; (2) grouting of over-burdened materials (which is rapidly becoming a more definite art and science and which, to some degree at least, is susceptible to laboratory studies); (3) g routing of a cutoff in granular materials in order to prevent under seepage beneath a major hydroelectric project; and (4) the grouting of subsurface voids in channels in limestone areas subject to large subsidence.
