The conventional slurry trench methods of constructing low-permeability vertical barriers have been widely used, namely, soil-bentonite (SB), cement-bentonite (CB) and slag-CB. More recently, in situ mixing methods to construct vertical barriers, such as Deep Soil Mixing (DSM) and the Trench Remixing and Deep wall method (TRD) have found increased usage. The TRD method was has been widely employed in Japan for nearly 15 years but has only recently been used in the United States. The TRD method is a one-phase process that involves the simultaneous, full-depth cutting and mixing of in situ soils with additives to create, in place, a continuous soil mixed wall. A blend of cementitious materials (granulated ground blast furnace slag and Portland cement) and slurry are injected as the milling/cutting proceeds horizontally resulting in continuous vertical mixing of in situ soils with the injected materials, without creating the open trench typical of other walling methods. Details of the technique will be presented as well as an evaluation of the wall performance at the Herbert Hoover Dike at Lake Okeechobee, Florida. Performance issues addressed include hydraulic conductivity, strength, in situ stress state, and cracking.
