Proceedings of the Fourth International Conference on Grouting and Deep Mixing, held in New Orleans, Louisiana, February 15-18, 2012. Sponsored by the Deep Foundations Institute; International Conference on Grouting, Inc.; the Geo-Institute of ASCE.

This Geotechnical Special Publication contains 189 peer-reviewed papers focusing on the science and technology of grouting. Papers describe advances in materials, instrumentation, control, and the basic science of grouting and deep mixing, and they lead the way to better understanding of and new applications for these technologies. Several papers focus on new developments in jet grouting and deep mixing, which are used extensively in the restoration of levee and flood control structures in and around New Orleans.

Topics include: anchors and piles; cement-based grouts; chemical and other grouts; dam foundation grouting, grout curtains, and cutoffs; deep mixing methods, applications, and performance testing; grouting for seepage control; highways and transportation; jet grouting; karst grouting; levees and flood walls; low mobility grouting; mine applications; permeation grouting; performance testing; structural support; and tunneling.

These papers are useful to geotechnical researchers and engineers, construction supervisors, and other professionals involved in the planning, design, and implementation of underground grouting and deep mixing programs.
