Abstract

It is difficult to prove the permeability characteristics of a cut-off wall. For this reason, a special testing unit for monitoring the wall permeability in-situ was developed. The testing unit can easily be installed at any depth of a cut-off panel by hanging it into the fresh slurry. After the installation it remains in the cut-off panel and can be used for a long period. The application and evaluation of tests results are described.
