USA Practice Slurry Wall Specifications 10 Years Later

Ten years earlier the authors prepared a paper on the then beginning state of practice regarding slurry wall specification in the USA. Changes (or lack thereof) and developments in the basic building blocks of specification criteria for the two types of walls constructed by the slurry wall technique; i.e., structural diaphragm walls and cutoff walls are reviewed.

Application of a Bentonite Slurry Modified by Polyvinyl

Soil-bentonite cutoff walls are usually used to contain the contaminants of landfills. The pumpability, permeability, and adsorption capability of the slurry are all crucial to the performance of the cutoff wall. In this study, the effect of polyvinyl alcohol (PVA) was used to improve the performance of bentonite slurry. A series of lab tests were conducted to evaluate the pumpability
