Concepts for the Future of Ground Improvement
2
State of the Practice:Solidification/Stabilization (S/S)and Isolation
Solidification – bind target in a solid block of low permeability material
Stabilisation – transform contaminants and reduce leachability
3
Isolation - cut off contaminants from receptors
