Description:
Grouts are becoming increasingly important in producing barriers to contaminated ground water flow at hazardous waste sites. Grouted barriers can be used at depths and under conditions where slurry trenches are impractical. To employ grouts to advantage at waste sites it is necessary to select materials that solidify or gel in the presence of industrial waste compounds that may be present; that are unaffected by aggressive chemical wastes; and that create impermeable barriers when injected into permeable units. A wide variety of test procedures have been employed in bench and pilot-scale evaluation of grouts.
