Federal Highway AdministrationFederal Highway AdministrationThis report presents the results of a laboratory and field research program investigating innovative method for design and control of chemical grouting in soils. Chemical grouting practice is reviewed and standard evaluation and measurement techniques are presented. Problems particular to chemical grouting design and construction control are also discussed, and interviews with experts in the grouting industry are abstracted. Results of laboratory and field efforts to remotely evaluate grouting procedures and processes, including geophysical grout evaluation systems such as electrical resistivity, acoustic velocity, borehole radar, geotomography and acoustic emission techniques to monitor hydraulic fracture, are also presented. Finally, proof-of-concept tests were carried out on several on-going grouting jobs to evaluate the use of procedural controls to monitor grouting progress, and the application of acoustic emission techniques to detect and control hydraulic fracture. This report is the first in a four-volume series. The others in the series are: FHWA/RD-82/037 Materials Description Concepts FHWA/RD-82/038 Engineering Practice FHWA/ RD-82/039 Executive Summar
