Abstract : The Falling Beam SoilSaw is a method for forming a continuous barrier wall at depths between 30 and 120 ft deep. The objective of this project was to fully develop and commercialize SoilSaw technology for use in underseepage control (pre- and postconstruction), slope stabilization, and as a method of containing contaminants at hazardous waste sites. Specifically, the objectives were to install a demonstration wall using the SoilSaw technology, determine the physical dimensions (width and depth) of the wall, and determine the in-place properties (permeability and strength). Wall specifications were: (a) permeability equal to or less than 0.000001 cm/sec, (b) wall width equal to 12 in., (c) wall depth for Phase 1 equal to 30 ft and Phase 2 equal to 120 ft and (d) unconfined compressive strength equal to or greater than 15 lb/sq in (psi). During the time frame of the CPAR study, several walls were constructed by Halliburton NUS for which USACE visually monitored but not strength or permeability data were supplied. Therefore, the results of the objectives mentioned above will be based on the CPAR data presented in this report. (MM)
