Abstract: The urban green infrastructures encourage the infiltration of the surface water but infiltration of the surface water into the building foundations are not desirable. This paper presents the studies of the seepage prevention measures of building foundations near the green infrastructures. The principles of seepage membrane and slurry wall used in the green infrastructure construction are introduced. A seepage prevention method and its optimum location are introduced. A case study of the green infrastructure construction and its seepage prevention measures are also presented in the paper.

Key words: Urban Green Infrastructures, Building Foundations, Seepage Preventions, Seepage Membrane, Slurry Wall
