<p>The present invention relates to a waterproof seal material or tape and a waterproofing method using the same capable of obtaining excellent constructability and quality stabilization after construction by utilizing self-adhesive waterproof sheets integrated with a high-density polyethylene film dually overlapped while bidirectionally crossing to each other and applying the waterproof seal material or tape to a connection part of the sheets. According to the present invention, the waterproofing method comprises: a step of spreading a primer after a concrete surface is cleaned up; a step of attaching the self-adhesive waterproof sheets to the top of the concrete surface by overlapping the edges of the sheets at a predetermined width; and a step of spreading the waterproof seal material to an end of the connection part where the sheets are overlapped. The waterproof seal material is formed by mixing 28-40 parts by weight of a polyurethane-based resin, 25-35 parts by weight of polyvinylbutyral, 12-17 parts by weight of polybutylene, 6-10 parts by weight of a polymer with 2-metyl-1-propene, 3-8 parts by weight of a tackifier, 4-8 parts by weight of process oil, 1-3 parts by weight of a viscosity control agent, 0.1-1 parts by weight of an antifoaming agent, and 3-8 parts by weight of natural cellulose.</p> |
