The invention provides a construction method for a self-adhesion waterproof roll. The construction method comprises the following steps: a, the self-adhesion surface of the self-adhesion waterproof roll makes contact with a body structure; b, a protection layer is poured on the surface of the surface of the self-adhesion waterproof roll. Compared with the prior art, the construction method is easy to operate, the self-adhesion waterproof roll and the body structure can be bonded into a whole permanently, the hidden danger of water leakage in the middle is avoided, even if a part of the roll is destroyed, water is limited within a small range, and therefore the reliability of a waterproof layer is completely improved.
