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
