Remediation of polluted sediments through deep freezing
Artificial ground freezing (AFG) is a well established technique first practised in South Wales in 1862. Since then many different temporary and permanent applications have been developed. AFG is mostly used in tunnels and for stabilising excavations, but there is an increasing interest in using AFG...
