PREPRUFE CJ Tape is a specially formulated, two sided, reinforced, pressure-sensitive tape. The bottom side of the tape has a highly aggressive, pressure-sensitive adhesive which is designed to adhere to penetrations, protrusions, PREPRUFE and BITUTHENE Membranes. The top side has another layer of adhesive and a protective coating. The protective coating protects the tape from the weather and UV light for up to 30 days after application.
PREPRUFE CJ Tape is used at construction joints in concrete that is cast against it. It is also used to patch damaged areas in the PREPRUFE membranes or in critical areas where a wider tape is required. The tape is a critical component of the PREPRUFE system since it is designed to develop a continuous mechanical bond to concrete that is cast against it.
