Type R Cavitray

Available in 3 variation(s).

Use


Integral shuttering tray/water check former. Also suitable for closing cavities.

Introduction


The Type R is a two-function cavitray. When intermediate upper floors of concrete are cast in-situ, it is utilised to close the cavity and prevent concrete entering. In addition, the Type R introduces a water check to the underside of the concrete, to prevent water tracking across the cavity. The upturned profile (rather than the down-turned profile) is not susceptible to accommodating course aggregate during the pouring of concrete, which might encourage capillary action if air voids are present and permit perimeter pooling.

Data

  • Type R size 1 = 2400mm x 135mm overall width with V section of 25mm x 25mm.
  • Type R size 2 = 2400mm x 160mm overall width with V section of 50mm x 50mm.
  • Angles 450mm x 450mm.
  • Standard 1.5mm solid polypropylene, black.
  • DPC Securtex top textured finish.  
  • Dual function product acting as water-check and also integral shuttering tray.
  • Upturned profile eliminates dangers of capillary action and pooling water.
