Repair, Evaluation, Maintenance, and Rehabilitation Research Program. Review of Consolidation Grouting of Rock Masses and Methods for Evaluation
Abstract
This study was undertaken to review consolidation grouting methods and to look at the application of consolidation grouting as a remedial measure for structures in the US Army Corps of Engineers (CE). Consolidation grouting may be defined as the injection of grout into discontinuities in a rock mass to control fundamental rock mass properties such as permeability, strength, and deformability. Consolidation grouting applications to improve engineering properties of rock mass foundations will increase in number and scope as facilities age and deteriorate. Modern method to improve economy, reliability. and planning of grouting programs for repair and rehabilitation of CE structures are required. Factors involved in the successful consolidation grouting of rock masses by cementitious grouting are reviewed. Properties of cementitious grouts, rock mass properties, grouting techniques, and methods to evaluate and to monitor the grouting job are discussed. Three cases histories of consolidation grouting performed on a rock mass for remedial purposes are presented.
