Drybase Construction Joint Tape
Drybase Construction Joint Tape, in combination with Drybase Elasticised Tanking Slurry, forms a durable waterproof seal for construction joints and cracks.
Drybase Construction Joint Tape is a synthetic rubber strip, approximately 0.8 mm thick. It is covered on both sides with an alkali-resistant and flexible polyester fabric mat, which forms a web on the edges.
The tape’s exceptional elasticity is maintained due to the robust adhesion of the fabric mat and synthetic rubber, which combine to form a strong bond with the concrete surface.
Drybase Construction joint tape is resistant to hydrostatic pressure:
- on the positive side
- on the negative side with appropriate support
