Mechanical Behavior of Soil-Bentonite Cutoff Walls
A soil-bentonite cutoff wall is a type of subsurface vertical barrier constructed by back-filling a trench with a mixture of soil, bentonite, and water. Although soil-bentonite cutoff walls are common, their mechanical behavior is not well understood. Current design procedures do not consider the …

Soil-Bentonite Cutoff Walls: Hydraulic Conductivity and Contaminant Transport
Soil-bentonite cutoff walls are commonly used to contain contaminants in the subsurface. A key property in determining the effectiveness of a cutoff wall is its hydraulic conductivity. There are important difficulties and uncertainties regarding the accuracy of commonly used methods of measuring …

Permeability and swell testing of selected South African bentonites
Bentonite, a natural clay composed predominately of montmorillonite has become a very useful product in Civil Engineering due to its extremely low permeability and high swell potential. Bentonite has been used extensively in countries like the United States of America, Canada and Europe as an …
