AKINAGA TAKUYA

To provide a connection method of water shielding sheets capable of securing water shielding property even when a water shielding sheet includes a protection layer composed of a woven fabric or a nonwoven fabric.SOLUTION: A method for connecting a plurality of water shielding sheets comprising a layer composed of a woven fabric or a nonwoven fabric and a water shielding layer with each other comprises: a step of installing one water shielding sheet and the other water shielding sheet among the plurality of water shielding sheets so as to have an overlapped portion; and a bonding step of connecting the overlapped portion via an adhesive. The adhesive is impregnated across the whole of a thickness direction of at least a part of the layer composed of a woven fabric or a nonwoven fabric in the overlapped portion. The adhesive is impregnated continuously in a direction perpendicular to a width direction of the overlapped portion.SELECTED DRAWING: Figure 2
