Betosieb – supersize formwork panel with lattice texture

Betosieb is suitable for all concrete surfaces where an anti-slip surface is equired, such as on stadium steps, platforms, or concrete surfaces with increased adhesion for subsequent sealing. Can be subjected to both longitudinal and transverse loads.

An overview of the main properties and benefits of our “Betosieb” shuttering board:

  • Supersize formwork panel made of veneered plywood based on DIN 68792
  • Phenolic resin film coating 300 g/m² on each side
  • Front: Westag lattice texture
  • Back: smooth
  • Anti-slip concrete surface R13
  • Sealed edges

Diagram for bending estimation

Technical advice: Area load calculated from pure concrete pressure without safety coefficients. Diagram applies to a 4-field beam, deflection in the outfield. Permissible bending stress = calculated with load safety factor 1.5 / load duration 0.9 / material safety 1.3. The technical data are mean values which may vary due to the natural fluctuations of the raw material wood.

Westafill joint tape

Single-sided self-adhesive polyethylene-based joint tape approx. 19 mm wide and 3 mm thick. It is used to seal the joints between formwork panels. The roll length of the Westafill joint tape is 10 m.

Westafill special filler resin

The high-quality two-component epoxy resin filler is suitable for shuttering construction, particularly for use with all film-coated plywood formwork panels from Westag.

Westafill special lacquer

The ready-to-use single-component paint offers a high degree of abrasion resistance and impact resistance, as well as good resistance to chemicals. It is used as edge protection for shuttering panels made of wooden composites.
