Abstract: Deformation crack seepage is a common problem in construction.Through numerous experiments and an explo-ration of constructional cases,a solution was found.By applying a flexible waterproof material with resistance to deforma-tion,which has the characteristics of high bond strength,high elastic modulus and water expansion to construct with the recombination construction method to satisfy the needs of the transformation of up and down sedimentation,and scaling transformation without seepage.
