ASO®-Tape

Thermoplastic Joint Tape For Waterproofing Joints

Properties:

  • Highly flexible
  • Simple, homogenous weld
  • No activation necessary
  • Impermeable to water even against negative pressure
  • Can be applied to matt damp substrates without priming

Product Details

Coat the prepared substrate

Coat the prepared substrate on both sides of the joint to be bridged with ASODUR-K4031 to a width min. 1 cm wider than the ASO-Tape being used. Then lay the joint tape and thoroughly bed into the adhesive layer with a trowel or pressure roller without voids or folds and coat over the top. In so doing, ensure that the joint tape is completely bedded. The adhesive or smoothing coat thickness should never be less than 1 mm. Overlap but joints by a min. of 5 to 10 cm and bond or alternatively hot air weld.

Expansion joints

Expansion joints always require a 2 mm joint tape and can either be laid tlush or in a loop dependent on the project. To accomodate expansion, leave an unbonded section of tape in the expansion area. Dependent on the installation and loading e.g. overhead use or negative water pressure, a reinforcing or supporting construction may be necessary.

Hot air welding

The joint tapes are cut to suit the project (butt joints or corner joints} and laid on a flat substrate. Butt joints are to be overlapped by a min. 5 cm. The overlap area is to be roughened with abrasive paper and cleaned. Welding is carried out with hot air equipment with a wide nozzle and a pressure roller. The welding temperature (reference values: approx. 300 – 350 °C) is to be set
by a trial weld. The joints in the tapes are laid on top of one another appropriately and fixed at the edges by selective welding in order to prevent slipping during welding. Then the wide nozzle of the hot air tool is drawn slowly and evenly over the overlap area and fully joined together with a pressure roller. Before installing check the weld for a complete w atertight bond
