Soil-bentonite slurry trench cutoff walls are widely used for seepage control, levee repair, and pollutant containment. Their widespread use in these critical applications requires a
Vertical barriers constructed using self-hardening slurries such as cement-bentonite were in use by the early 1970’s and slag-cement-bentonite (slag-CB) slurries were first used in the
Soil-bentonite slurry trench cutoff walls have long been used to control ground water flow and contaminant transport. Previous studies have shown that hydraulic conductivity of
Much of the information presented in this article should be considered common knowledge by those who are regularly engaged in geotechnical design or construction. This
The adoption of the United States Environmental Protection Agency’s Coal Combustion Residuals (CCR) regulations has stirred renewed interest in the stabilization/solidification (S/S) of fly ash
Geotechnical engineers understand there is uncertainty and risk in the input parameters for slope stability analyses and within the analysis methodologies themselves. Decades of research
Significant Project Features: Installation of 1,850 linear feet of sand filter trench using the bio-polymer slurry trench method Use of guar gum for slurry creation
Significant Project Features: Thermal treatment of 35 columns of impacted soil via large diameter auger steam injection Injection of approximately 45,000 lbs. of Zero-Valent Iron
