FAB Joint sealing tape 89ZH

Substrate

Properties/tests

• The substrate must be prepared in accordance with the processing guidelines of the waterproofing and/or bonding material to be used. As a rule, the substrate must be load-bearing and free of dust, dirt and other adhesion-reducing substances.

Processing

Processing

• Cut the required length of tape.
• Pre-fill the joint edges, e.g. with KMB. Press the edges of the tape into the fresh waterproofing.
• Then coat the edges of the tape with KMB or similar. The grey plastic should be covered in a width of about 2 cm.
• To glue the tapes together, heat the plastic with a hot air gun until it liquefies. The second part of the tape is pressed into this liquid plastic (use a firm base). When it has cooled down, the connection is tension-proof and watertight.
• If tensile forces are transmitted to the tape, it is recommended to bond the tape to the substrate with epoxy resin HADALAN® MBH 12E in combination with actuator HADALAN® SM 57DD.
• After completion of the waterproofing work, peel the fleece cover off the joint cover tape to achieve a clean and accurate joint appearance.
• The joint seal must always be protected before backfilling so that no compressive and/or tensile forces can act on the tape.

Notes

• Ensure homogeneous binding of the tape edges.
• Do not completely cover the joint tape with the respective waterproofing, leave a sufficiently large expansion zone.
• Tensile forces should not be transmitted to the tape to avoid tearing or cracking in the bonding zone.
• The joint tape must be protected with suitable protective systems before backfilling the excavation pit.
• Observe the processing instructions of the respective waterproofing product used.
• In areas that are not covered with soil, the joint cover strip must be protected from the weather. Make sure that the protection does not restrict the functionality.
