Abstract

The invention belongs to the field of building, and particularly relates to a method for preventing seepage at seam crossings of prefabricated industrial external wallboards. According to the method for preventing seepage at seam crossings of prefabricated industrial external wallboards, edge connection slots are formed in the edges of external wallboards; two edge connection slots are formed in seam crossings of two adjacent external wallboards to form a complete seam connection groove; and the seam connection groove is filled with joint mixture. According to the method for preventing seepage at seam crossings of prefabricated industrial external wallboards, the seam crossings approach the rainwater as little as possible, so that seepage channels are not formed; the seepage pressure of the water is cut off or lightened, and then the waterproof efficiency of the walls is ensured.
