... and performance monitoring of a 1,500 m (4,900 ft) long S-B cutoff wall in a dam and dike constructed of sandy material. The cutoff wall extended to a maximum depth of 23 m (75 ft) and had a width of 0.9 m (3 ft), except for a 305 m (1,000 ft) long section where the width was increased to 1.5 m (5 ft...

... This paper compares two methods of constructing vertical cutoff walls when considered in the context of controlling the migration of waste materials. It will be argued that the conventional slurry trench method has significant advantages over the vibratory beam injection (VBI) method...

... A comprehensive laboratory investigation was carried out to determine a suitable mix of cement-bentonite for a slurry trench cutoff wall for Caniapiscau Reservoir project in James Bay, Canada in 1980. Specifications required the mix to have a permeability of less than 0.01 μm/s and to be able...
