Grouting is a construction process by means of which the highly erratic permeability and deformability of foundation rock and soil are homogenized. The main parameter governing the design and construction of grouting works is the permeability of the rock or soil, which is established by means of field permeability tests. This book assembles information on rock and soil grouting from various sources, together with the author's personal experience on several grouting projects. Some aspects of permeability testing of rock and soils are elaborated, and the use of theoretical ground water percolation studies for clarification of design options for grout curtains are presented. The results achieved by grouting are presented and analysed on examples of constructed grouting works (curtains, tunnels, foundations, lifting of structures). Particulars of the performance of the permeability tests and their evaluation are studied in some detail, since they can very much distort the results obtained, and thus lead to erroneous design assumptions. Systematic grouting and adjustment of the injection process to the development of grout consumption and pressure during injection is discussed in connection with the achievement of the required permeability standard. The application of grouting to reduce the permeability and the deformability of the foundation of dams and hydrotechnical structures is presented, together with a number of illustrative examples. Characteristics of contact and consolidation grouting of dam foundations and tunnel linings are described. The possibilities and examples of rock prestressing by means of grouting are reported, and the results from several applications are discussed. Examples of lifting and levelling leaning structures by means of grouting are also reviewed. The book is illustrated by 180 drawings and 20 photographs, and a list of symbols used in the formulae, plus a glossary of specific terms use.

When finding another location, redesigning a structure, or removing troublesome ground at a project site are not practical options, prevailing ground conditions must be addressed. Improving the ground—modifying its existing physical properties to enable effective, economic, and safe construction—to achieve appropriate engineering performance is an increasingly successful approach. This third edition of Ground Improvement provides a comprehensive overview of the major ground improvement techniques in use worldwide today. Written by recognized experts who bring a wealth of knowledge and experience to bear on their contributions, the chapters are fully updated with recent developments including advancements in equipment and methods since the last edition.

The text provides an overview of the processes and the key geotechnical and design considerations as well as equipment needed for successful execution. The methods described are well illustrated with relevant case histories and include the following approaches:
    Densification using deep vibro techniques or dynamic compaction + Consolidation employing deep fabricated drains and associated methods + Injection techniques, such as permeation and jet grouting, soil fracture grouting, and compaction grouting + New in-situ soil mixing processes, including trench-mixing TRD and panel-mixing CSM approaches.
      The introductory chapter touches on the historical development, health and safety, greenhouse gas emissions, and two less common techniques: blasting and the only reversible process, ground freezing. This practical and established guide provides readers with a solid basis for understanding and further study of the most widely used processes for ground improvement. It is particularly relevant for civil and geotechnical engineers as well as contractors involved in piling and ground engineering of any kind. It would also be useful for advanced graduate and postgraduate civil engineering and geotechnical students.

      The foundation of structures and the construction of underground railways in urban areas would be impossible without the use of diaphragm walls, grouting, anchors, micropiles, slender retaining walls, etc. Based on the author's own experience and taking into account the findings of various other authors, this book explains these methods in an intelligible manner, enabling the reader to judge for himself their suitability in construction practice. The aim of the book is to instruct experts in the correct application of grouting methods, and the correct choice of drilling systems and tools. It provides mainly practical information, and describes the most suitable, up-to-date technology available. Grouting applications in Czechoslovakia and abroad are illustrated by a series of practical examples. The book is designed for students of civil engineering faculties specializing in structural foundation, specialists of building companies, and experts in structural foundation. It will also be appreciated by experts in underground railway and tunnel construction, in structural engineering and urban development (landslides), as well as by manufacturers of the respective technology.

      Minimize loss of revenue and the downtime of critical assets by avoiding foundation cracking, poor bonds, and initial alignment changes. After their successful introduction as a maintenance material, machinery grouts are now being used for equipment placement in new construction. While certainly suitable for both markets and applications, a successful installation depends on proper grout selection, application, foundation preparation, and forming methods. Therefore, guidelines on their uses and limitations are needed for engineers and maintenance personnel.

      Based on 45 years of field experience, The Grouting Handbook collects a vast amount of information into a practical and user-friendly reference for mechanical and civil engineers. The book focuses on four basic elements of grouting:
      • The soil and its load-carrying capability;
      • The foundation and its mass, design, concrete mix, installation and curing procedures;
      • Anchor bolt technology, design and installation;
      • Epoxy grout comparison, material selection and installation.
      From the ground up, The Grouting Handbook takes you step by step through the grouting process. Clear, straightforward directions give you details on preparing the foundation and surface and selecting the best material and method. Comprehensive yet concise, this is a convenient handbook for veteran and rookie engineers alike.
      • Organizes a comprehensive amount of information into an easy-to-use reference
      • Provides advice for selecting the proper grouting material and method for the task at hand
      • Contains tips and practical solutions for common problems.

      Fifteen years have passed since I was working at a dam site super­ vising grouting work. That was not the first time that I had to car­ ry out engineering geological investigations for several similar projects, which always included testing programmes to find out the permeability of the rock, and often I was in charge of grouting work. It thus attracted my attention when this particular grouting programme did not run as intended: most of the grout holes took only very little grout! It could not be the aim of the invested work simply to drill holes and fill them again without bringing about any further improvement. Fortunately, I had the chance to be en­ gaged in many other grouting programmes in the following years and used all these examples to analyse as thoroughly as possible the permeability of the rocks being treated in view of their grout­ ability. The more I studied, the stronger my conviction grew that our rules which had decided the grouting of rock for many de­ cades should be developed further, and therefore I occupied my­ self with contributing some ideas for a new basis to investigation and judgment of permeability of rock and for a more adequate application of this technology.

      The increasing need to redevelop land in urban areas has led to major development in the field of ground improvement, a process that is continuing and expanding. Vibratory deep compaction and grouting techniques have also been increasingly applied to solving the problems of urban development, whether from tunnelling, excavation, building renovation or bearing capacity improvement and settlement reduction.

      The second edition of this well established book continues to provide an international overview of the major techniques in use. Comprehensively updated in line with recent developments, each chapter is written by an acknowledged expert in the field.

      Ground Improvements is written for geotechnical and civil engineers, and for contractors working in grouting, ground improvement, piling and environmental engineering.

      Methods for improving ground and soil have undergone significant developments in recent years, particularly in terms of application and usage, and many innovative techniques have been introduced. However, it is of significance that in many areas the design process still lacks a theoretical framework.

      The papers included in this volume, written by international authors, deal with a cross-section of problems faced by many practising engineers and provide advice and guidance on how these problems can be dealt with in a practical manner.

      Unlike similar titles providing general information on ground improvement, Jet Grouting: Technology, Design and Control is entirely devoted to the role of jet grouting – its methods and equipment, as well as its applications. It discusses the possible effects of jet grouting on different soils and examines common drawbacks, failures and disadvantages, recent advances, critical reviews, and the range of applications, illustrated with relevant case studies.

      The book addresses several topics involving this popular worldwide practice including technology issues, the interpretation of the mechanisms taking place during the grouting, the quantitative prediction of their effects, the design of jet-grouted structures, and procedures for controlling jet grouting results.
        Discusses the design criteria for jet grouting projects and reviews existing design rules and codes of practice of different countries + Provides practical methods for design calculations of the most important jet-grouted structures such as foundations, earth retaining walls, water cut-offs, bottom plugs, and provisional tunnel supports + Includes the current standard control methods and most innovative techniques reported for the implementation of quality control and quality assurance procedures
          Jet Grouting: Technology, Design and Control analyzes the typical jet-grouted structures, such as foundations, earth retaining walls, water cut-offs, bottom plugs and tunnel supports, and serves as a practical manual for the correct use of jet grouting technology.
