Abstract
A new repairing method development for the damage point of impervious sheet from leaking, with out drying the water using a geosynthetic clay liner of bentonite layer which adhesives to geomembrane. When the geosynthetic clay liner is placed to the damage point, its swelling, high liquid limit and effective power by the sandbag brought plastic deformation. It is conceivable that these total factor and of it's adhcsives caused non-permeability of the damage point. At he execution scene using this method, it is confirmed that the water leaking had reduced 1/6, cnnparing before execution.
