Current USA Practices: Slurry Wall Specifications

The critical design criteria and the resulting specifications for slurry trench diaphragm walls and cutoff walls are discussed. To establish diaphragm and cutoff slurry wall design criteria and specifications, the designer must clearly establish the objectives or end results that are to be obtained, and shape his specifications accordingly. There are many portions or applications of slurry wall work where truly an end-result specification may be appropriate. However, the application of end-result specifications in the present practice is a long way off until the owners and engineers gain a more thorough understanding and knowledge of the technical and construction procedures involved in slurry trench work.
