Crack repairing tape and rooftop waterproofing Method of concrete structure using the same

KIM SO JOONG / CHOI YOUNG JUN

The present invention relates to a tape for repairing cracks and a method for waterproofing and repairing roof urethane using the same, wherein the tape for repairing cracks repairs a coating crack (35) when a waterproof coating (30) of an urethane material is formed on a roof (R) having a joint (20) to cover the joint (20) and the coating crack (35) is formed on the waterproof coating (30) along the joint (20). The tape for repairing cracks includes: a cover surface (11) covering the coating crack (35) and having a first width (D1); and a pair of perforated surfaces (12, 12′) formed on both sides of the cover surface (11) to cover the periphery of the coating crack (35), having a plurality of perforations (12a) and having a second width (D2). Therefore, the tape for repairing cracks can fundamentally prevent rainwater from being permeated through cracks in coating.

본 발명은 크랙 보수용 테이프 및 그를 이용한 옥상 우레탄 방수 보수공법에 관한 것으로서, 이중 크랙 보수용 테이프는, 줄눈(20)이 형성된 옥상(R)에 우레탄 재질의 방수도막(30)이 상기 줄눈(20)을 덮도록 형성되고, 상기 방수도막(30)에 상기 줄눈(20)을 따라 도막크랙(35)이 형성되었을 때 상기 도막크랙(35)을 보수한다. 이러한 크랙 보수용 테이프는, 도막크랙(35)을 덮는 것으로서 제1폭(D1)을 가지는 커버면(11), 및 커버면(11)의 양측에 형성되어 도막크랙(35) 주위를 덮는 것으로서 다수의 천공(12a)이 형성되고 제2폭(D2)을 가지는 한쌍의 천공면(12)(12')을 포함한다.
