Vandex Construction Joint Tape

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.

Areas of Application:

Vandex Construction Joint Tape, in combination with Vandex BB75 E flexible waterproofing slurry, forms a durable seal of construction joints and cracks, in damp concrete conditions.

Vandex Construction Joint Tape is resistant to hydrostatic pressure:

• on the positive side
• on the negative side only with appropriate support

Consult Safeguard Europe Ltd technical literature for details. Safeguard Europe Ltd can also provide a design and specification service and it is recommended that they are consulted early in the design process.
