Cement based grout has been used for years in purpose of decreasing permeability of rock mass and increasing stability. In most of the grouting projects, design andexecution of grouting works are based on practical knowledge. To improve the performance of these projects, studies in different aspects of grouting are performedand theories are developed to provide better understanding about the grout material and its behavior in response to geology and design settings.In this report, impact of using methods and theories for formulating variation of grout material characteristics, estimating flow and penetration, and also distinguishingjacking due to grout pressure are reviewed and prospects of future developments are discussed. Optimizing the models of time and cost estimation in such projects was another point of interest.
