Paraseal® Permanent Seam Tape™ is a rubberized asphalt membrane laminated to a polyethylene reinforcing film. A removable release paper protects the adhesive membrane face until removed during installation.
Permanent Seam Tape is used primarily for sealing the seams of Paraseal applications when flood testing is desired.
It is used on all seams of Paraseal Saltwater Grade applications and with Paraseal LG when installed for vaporproofing.
The inherent adhesive and waterproofing properties of the rubberized-asphalt membrane effectively seals the HDPE liner face on Paraseal products to render the bentonite a secondary back-up.
