NBS Clause J10-340
J10 CEMENTITIOUS MORTAR TANKING / DAMP PROOFING
To be read with Preliminaries / General conditions.
Vandex Construction Joint Tape bridges and seals construction joints and cracks in concrete structures. Vandex Construction Joint Tape is a synthetic rubber strip, approximately 0.7 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 properties of the fabric mat and synthetic rubber combine to ensure a strong bond with the concrete surface, maintaining excellent elasticity of the tape.

Vandex Construction Joint Tape is resistant to hydrostatic pressure:
- on the positive side
