Alumasc Roofing - Expansion Joint Tapes

Fully-integrated flat expansion joint sealed into the waterproofing

RedLINE and FlamLINE expansion joint tapes are compatible with bituminous membranes, asphalt and epoxy. They are ideal solutions for new-build projects, as well as for joint repair within refurbishment projects.

Both products can easily be integrated into waterproofing build-ups, but can also accommodate projects with complex changes in direction. The two solutions can also be joined together on-site, permitting a phased approach to a continuous joint which means there are no weak points and the joint can be installed efficiently.

RedLINE

RedLINE expansion joint tape consists of a highly elastic movement section made of EPDM and two laterally flexible adhesive flanges. The flanges are reinforced by a polyester fleece that stabilises the EPDM, forcing movement to occur only in the movement section and provides a surface that gives high bonding strength.

FlamLINE

FlamLINE expansion joint tape is compatible with torch-on roofing membranes and is manufactured from a single flexible sheet of high grade Butyl-Elastomer.

The flanges contain a mesh that, like RedLINE, stabilises the adhesive flanges for sealing the waterproofing membrane to it. Movement is again forced to occur in the section that is positioned over the expansion joint.
