Abstract: With the urban development, the deep excavations are increasing in quantity and also the excavation depth is also getting greater. The groundwater control during the excavation becomes critical for the success of the excavation. This paper reviews the stateoftheart slurry wall construction techniques. A new seepage control wall that was developed by a Japanese firm, Raito Kogyo Co. Ltd is introduced. This wall which has a name of EcoClay Wall is environment friendly compared with the conventional slurry wall types. It has the advantage of excellent groundwater control, long service life, easy to construct, as well as no soil spoils during the construction.

Key words: Deep Excavations, Seepage Control, EcoClay Wall Method, EnvironmentFriendly
