Practical Handbook of Grouting Soil, Rock, and Structures









Preface

When I entered grouting in 1952, it was a generally undeveloped art with most

of the players professing magical powers. Work was performed on a somewhat

hit or miss basis with results that varied from excellent to complete failure. Little

equipment specifically built for grouting was available, and most work

was accomplished with simple water-cement suspensions, typically based on high

watercement ratios subject to large bleed, shrinkage, and poor durability.

Fortunately, that has all changed. Although we still have players that profess

magical powers, grouting has become well-established science, and work today

can be designed and performed according to sound engineering principles with

a good understanding of the processes that occur.

To cover all pertinent subject matter and facilitate its review, the handbook

is divided into three parts. Part I discusses the grouting process in a general way

and should be of interest to all readers. Here, the many conditions for which

grouting can be a solution are described, as are both grouting materials and

injection fundamentals. The five general types of grouting—permeation, compaction,

fracture, replacement, and fill—are discussed as is the pertinent methodology

for the main applications of

grouting, in rock, soil, and into concrete and

masonry structures. Separate chapters discuss specialized applications such as

Grout Jacking, Grouting in Pipes and Conduits, Leakage Control in Structures,

Grouting of Underground Structures, and Grouting in Extreme Environments.

Following a discussion of the very specialized but seldom used application of

Use of Explosives in Grouting, the section ends with a discussion of Emergency

Response Grouting.



Part II will be of particular interest to designers, engineers, and those responsible

for quality control, although the material presented should be useful to all

grouting participants. This part discusses the criteria upon which a grouting program

should be based. Design issues including required surface and subsurface investigation

are covered, as are monitoring and control of the actual work. Included

are the numerous activities that ensure proper performance, including chapters on

Understanding Geology, design and specification of grouting, quality control and

verification, and Numeric Analysis for Grouting. This part ends with discussion relative

to the preparation of contract documents, pay items, and The Games Contractors

Play, which must be considered when preparing those documents.
