ABSTRACT
Technologies for soil stabilization and ground improvement are well documented. Infrastructural growth has pushed the boundaries of challenges of the projects, which nowadays must be executed on soft grounds, or on engineered soils due to site specific serviceability requirements. Infrastructural projects demand a quick and economical solution for the soil stabilization and ground improvement, as time and cost are the key factors that govern timely completion of the project with planned margin. Frequent hurdles are very common during execution of ground improvement and soil stabilization schemes which, otherwise, are not documented; and to overcome them, innovative site-based solutions are required to bridge through these hurdles. This paper reports insights and arrangements of important ground improvement projects and presents two case studies namely, cement stabilization for subgrade improvement for a highway project at Mozambique and; remedial measures against seepage discharge into the vertical shaft in a major infrastructural project in the eastern part of India. These case histories demonstrate some of the execution problems and how quick and innovative remedies ensure that the functional requirement of the structure is restored.
