The mass transport in landfills with clay liner is significantly controlled by diffusion processes. Regarding the evaluation criteria 'permeation rate and retention period' and the interdependence of the pollutants in the solute the diffusion processes are of complex nature. This presented research work deals with diffusion processes for different ...

The blower door measuring system consisted of a variable frame with airtight foil and integrated speed-controlled blower, a volume flow meter and differential pressure manometer. It was not possible in all cases to generate sufficient volume flow for achieving the desired pressure gradient, both in the atrium and the building as a whole. In these c...

The seminar presented new findings in the fields of surface coverings and alternative liners, vertical liners (with a contribution on developments in Great Britain), and basic constructive problems of liner systems. Another session discussed problems, experience and developments of sealing walls, especially quality assurance measures during sealing...

Fine-grained mineral liners may contain not only clay minerals but also reactive non silicate constituents, primarily carbonates and organic compounds but also iron oxides/hydroxides as well as sulphates and sulphides. The present German guidelines on landfill construction only contain rather conservative limit values for this substances or do not ...
Zur Sicherung von Deponien und Altlasten mit dem Ziel eines langfristig wirksamen Grundwasserschutzes werden seit Mitte der 80er Jahre Kombinationsdichtungen (Verbund aus Kunststoffdichtungsbahn und mineralischer Dichtschichten) eingesetzt. Um deren Langzeitbestaendigkeit auch unter extremen Bedingungen bewerten zu koennen, wurden Permeationsmessze...
