While red mud functions well in impermeability, it can do better when mixed with lime. The permeability tests were implemented according to GB/T 50123--1999. The findings indicated that in the laboratory, the permeability coefficient of consolidated red mud-artificial film was （7.3 -7.4） × 10^-9 cm/s when 8% lime was mixed to consolidate the red mud that was cured for 28 d. In pilot tests, the permeability coefficient of consolidated red mud（8% lime） sandwiched with artificial film with different thickness was 6.32 × 10 ^-9 - 1.89 × 10 ^-7 cm/s. Research results were applied to the engineering case of a aluminium factory in the midland of China.
