| Abstract |
The use of chemical grout for bottom sealing waste sites requires careful consideration of interfering reactions from contaminated soil or ground water. The cementing reactions in the acrylates and urethanes are very specific. The presence of reducers, oxidizers and complexors can make the grouting solution ineffective. Sodium silicate grouts that form by gel formation from a soil are not affected by oxidizing or reducing compounds. They are however sensitive to pH and the concentration of divalent and trivalent cations. The major problem with silicate grouts is accelerated setting which prevents the grout from penetrating the zone being sealed. The variety of possible grout/waste reactions is so broad that field testing with water and soil (or sediment) samples from the zone to be grouted is the most practical approach to selecting grout formulations and designing the grout program. |
