Book Description
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.

Book Description
It is a truism that we can no longer freely pick areas with the most suitable ground conditions for building purposes. Soils must often be improved in order to take the loads from buildings, roads and other objects. This volume contains papers covering a range of relevant topics and issues.

Book Description
The study of the solid part of the earth on which structures are built is an essential part of the training of a civil engineer. Geotechnical processes such as drilling, pumping and injection techniques enhance the viability of many construction processes by improving ground conditions. Highlighting the ground investigation necessary for the process, the likely improvement in strength of treated ground and testing methods An Introduction to Geotechnical Processes covers the elements of ground treatment and improvement, from the control of groundwater, drilling and grouting to ground anchors and electro-chemical hardening.

Book Description
Lime-cement columns were constructed to improve soft ground as part of a test embankment program at the I-95/Route interchange in Alexandria, Virginia. Two different commercial laboratories performed tests on treated soil, and they produced very different measurements of unconfined compressive strength. Further, both sets of results were different from test results available in the published literature for similar soils. This situation created uncertainties and a conservative design philosophy. The goals of this research project were to assess factors that influence strength gain of lime-cement-soil mixtures, to develop a detailed laboratory test procedure that produces consistent results, and to determine the reasons that the strengths measured by the private firms were so different. A suitable laboratory procedure was developed and applied to three soils: one from the I-95/Route interchange site and two from the site of a potential future application of lime-cement columns in West Point, Virginia, at State Route 33. Key findings from the research were that (1) drying and subsequent restoration of soil moisture prior to treatment can decrease the strength of the mixture, (2) the mixture strength decreases as the ratio of soil water content to cement content increases for 100 percent cement-soil mixtures, (3) the addition of lime can increase the mixture strength for some soils and decrease the strength for others, and (4) presenting the test results in the form of contour plots of unconfined compressive strength can be very useful. The reasons for the different results from the two private firms are explained by differences in the test procedures that were used.
