Case histories of ground improvement solutions using jet-grouting

ABSTRACT
The aim of this paper is to present the main design and construction criteria considered on some vertical
jet-grouting solutions adopted by Tecnasol FGE. On these solutions ground improvement by vertical
columns was successfully used as an alternative to traditional solutions, such as concrete cast in-situ pile
foundations, earth retaining sheet pile walls and micro-piles for underpinning. On each case history, the
following topics are presented: main scenario, geotechnical conditions, initial solution, main design criteria
and construction issues.
