PURPOSE: To improve bonding force for a covered face of a waterproof sheet forming a waterproof layer made of a hardening component by bonding the waterproof sheet through a hardening agent layer so as to obtain excellent waterproof and moistureproof effects stably.
CONSTITUTION: A waterproof sheet 4 forming a waterproof layer 3 made of a hardening component composed mainly of rubber asphalt on a base material 2 is constituted in such a way that its waterproof layer face is directed toward a structural body 1 and it is bonded through a hardening agent layer 5 for a hardening element of the hardening component on a surface of the structural body 1 to be waterproof-treated. Consequently, bonding force of the waterproof sheet 4 for a covered face of the structural body 1 is improved and excellent waterproof and moistureproof effects can be obtained stably.
