ABSTRACT

Among the positive cutoffs, vib walls represent the most economical sealing element for hydraulic structures. Vib walls are preferably used as impervious barriers for dykes, low dams, and around landfills. The commonly maximum attainable depth of vib walls is about 25 m, however, recently constructed vib walls have reached depths of up to 30 m. Vib walls are also known under the name of “thin walls”, “vibrated beam slurry walls”, “narrow walls” and “paroi mince” (in French). A new method of vib wall construction is the Vibrosol technique, which offers great advantages especially for the sealing of post-heightened earthfill dams.
