The present invention relates to an embedded sealant using a multi-coupling method, which temporarily couples a vertical coupling part and an extended cover part of a second sealant to the bottom surface and two points on one surface of a body of a first sealant in multi-stages before secondary concrete is placed, thereby preventing the vertical coupling part of the second sealant from being separated due to the weight of a horizontal cover part. |
