Rasco SAM Corner Tape

Self-adhesive sealing and strengthening tape for use within the Rasco SAM system in accordance with DIN 18533, EN 13969 and DIN V 20000-202

300 mm wide self-adhesive, flexible, crack-bridging sealing tape made from polymer-modified bitumen, with a cross-laminated, tearproof HDPE-carrier film on one side.

The 50 mm vulcanisation strips consist of pure bitumen compound. The purpose is to achieve better joints between the materials by sticking compound on to compound and so ensuring even better sealing.

SAM Corner Tape serves as sealing and strengthening tape for all corners, edges and hollow edges in the Rasco SAM system.

It can be applied to vertical and horizontal surfaces foundation slabs, foundations, balconies, terraces, underground garages and cellar walls as well as all known and suitable mineral substrates.
