PRODUCT DESCRIPTION

VANDEX CONSTRUCTION JOINT TAPE bridges and seals
construction joints and cracks in concrete structures.
VANDEX CONSTRUCTION JOINT TAPE is approximately
0.7 mm thick. It is a synthetic rubber strip covered on both
sides with an alkali-resistant and flexible polyester fabric
mat, which forms a web on the edges.
The combined properties of the fabric mat and synthetic
rubber 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 BB 75 E flexible waterproofing slurry, forms
an excellent and durable seal of construction joints and
cracks, in damp concrete conditions.
Areas of application: construction joints and cracks.
VANDEX CONSTRUCTION JOINT TAPE is resistant to
hydrostatic pressure:

• on the positive side
• on the negative side only with appropriate support
  On the negative side movement cracks should be routed out
  first and filled with VANDEX UNI MORTAR 1. Water leaks
  should be waterproofed with VANDEX PLUG first.
