Abstract

In recent years, thin slurry walls installed by vibrating a beam into the ground and injecting a suitable slurry as it is withdrawn have been used successfully and economically in a variety of applications, most notably as (a) permanent seepage cutoffs either in new or existing dams or levees, (b) a means of temporarily controlling groundwater during construction, and (c) a device for containment of toxic wastes.

This paper describes the equipment and construction techniques for installing the cut-off, and details of various types of slurries suitable for different applications are given. The results of field investigations undertaken to assess the permeability and continuity of vertical and battered (inclined) slurry walls are presented.
