The invention discloses a method for making a GCL (geosynthetic clay liner) vertical cut-off wall, and belongs to the field of seepage prevention. The method comprises the following steps of digging a groove; rolling up GCL with a round tube with the needed balance weight, fixing one end of the GCL to the top of the groove, and downwards inserting the GCL vertically along the wall of the dug groove, wherein the length of the GCL is larger than the depth of the groove; slowly unrolling to lay the GCL to the bottom of the groove along the wall from top to bottom, and fixing the GCL to the wall in an attached manner, then, taking out the round tube, and pouring slurry to the groove to carry out solidification so as to form the GCL vertical cut-off wall. The method for making a GCL vertical cut-off wall has the advantages that the effect of seepage prevention is good, and construction is easy.
