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. Water leaks should be waterproofed with Vandex Plug first. Advantages „ Economical and safe „ Can be applied onto damp substrate „ Resistant to hydrostatic pressure „ Permanently flexible „ Can be bonded to concrete surfaces with Vandex BB 75E-Z or Cemelast waterproofing slurry „ Simple tape joints bonded with Vandex BB 75E-Z or Cemelast Description 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 combined properties of the fabric mat and synthetic rubber ensure a strong bond with the concrete surface, maintaining excellent elasticity of the tape. Properties Product Code: 751010 Material: synthetic rubber Thickness mm: approx. 0.7 Total width mm: approx. 180 Width of fabric web mm: approx. 30 Roll length: 30m Elongation at lateral failure: % 260 Water vapour diffusion resistance 45‘000 index: All data is averaged from several tests under laboratory conditions. In practice, climatic variations such as temperature, humidity, and porosity of substrate may affect these values. Chemical Resistance Vandex Construction Joint Tape offers resistance to salt solutions, dilute acids and alkali solutions; low resistance to mineral oils, benzenes and strong solvents. Technical Support Parchem offers a comprehensive range of high performance, high quality, flooring, jointing and repair products for both new and existing floor surfaces. In addition, the company offers a technical support package to specifiers, end-users and contractors, as well as on-site technical assistance throughout its own national outlets and via international appointed distributors. Application Instructions Preparation of substrate The substrate must be clean, sound and free of any surface contamination. Any unevennesses or holes must be made good. Using standard methods such as chiseling, brushing, wet or dry sandblasting or cutting, remove all loose material, cement laitance, and any contamination back to a sound and clean concrete substrate. Dust, oil, tar, paint and grease must be removed. Smooth surfaces must be roughened. Clean all chiselled out areas, shutter-tie holes, etc. and pre-water until the concrete is saturated. Following this, fill the areas with Vandex Uni Mortar in layers, the number depending on the thickness to be filled. Water leaks must be stopped using Vandex Plug. Application The damp (not wet) substrate must be sound, open-textured, clean and free of oil and grease. Irregularities and surface voids must be made good. April 2013
