Both on minor and major work sites, soil treatment provides a technically, economically and environmentally balanced solution for problems with excavated soils. This document is a revision of BRRC’s good practice for soil treatment with lime and/or cement (R74/04), which was prompted by the replacement of Belgian standards with European standards.
The revised code consists of three big chapters.The first is about knowledge of soils. Good knowledge of the soil in place is essential with a view to deciding whether there is any use in treating it, choosing the appropriate treatment agent, and making a first estimate of the amount of treatment agent to be used. In this respect the chapter describes the behaviour of the various types of soil and the characteristics for discriminating between them, and also presents an overview of the tests to be made in the laboratory. The second chapter describes the various treatment agents and their effects on soils (processes involved in soil improvement and stabilization). The third chapter describes the organization of works and reviews the various types of equipment available for soil treatment. An appendix shortly defines the basic soil mechanics concepts that must be mastered for a good understanding of the processes described in the code.
This theoretical reference work is a necessary complement to the four practice guides to the various applications of soil treatment:

  • soil treatment for trench backfills and pipe embedments;
  • soil stabilization for subbase layers;
  • soil improvement for earthworks and capping layers;
  • soil treatment for base layers under industrial floors.
