ABSTRACT
The successful use of chemical grouting to solve a field problem hinges on many factors. They include proper analysis of the problem, selection of the most effective grouting materials and method of placement, and finally having a gel form in the proper location and of the proper extent. This series of actions is not haphazard. Data and experience exist from which, by logic or other deductive processes, intelligent choices can be made which are related to optimum chances of success. The summation of this data may, collectively, be termed grouting technology. That portion of the technology which deals with having a gel form in the proper (or desired) location is the subject of this chapter.
