A laboratory testing program was conducted to investigate the feasibility of using urethane as grout for the formation of in situ waste barriers. Injectability, reduction in hydraulic conductivity, and the size of the formed barrier were investigated. Results indicated that the performance of the urethane barrier was affected by the acid and base test chemicals. The hydraulic conductivity of the urethane-grouted sand using deionized water was measured to be on the order of 5x10{sup {minus}8} cm/s. A k value in the range of 1 x 10{sup {minus}4} cm/s to 1 x 10{sup {minus}6} cm/s was measured using acid and base solutions. Accordingly, a permanent-specific permeability test should be conducted to judge the suitability of the urethane grout as a barrier material depending on the intended application.
