Commonly used in both horizontal and vertical applications, Viaflexs Butyl Seal Tape is also effective for adhering barrier materials to properly prepared concrete walls and footings. Its flexible composition accommodates minor movement and surface irregularities, creating a long-lasting seal that resists water intrusion and air leakage. Whether used in crawl spaces, basements, or other controlled environments, this tape plays a key role in maintaining the integrity of vapor retarders and liners where seams and connections are vulnerable to exposure or damage.
