Application

Suitable for use in new build projects, where a protected membrane or green roof system is required, including:

  • Flat roofs (including 'zero falls').
  • Protected roofs.
  • Green roofs.
  • Terraces.
  • Podium decks.

Primarily used for concrete substrates, but can also be used on plywood and for a warm (inverted) or cold roof configuration. Protection can be either in the form of polystyrene insulation (warm roof), round washed pebbles, paving/ podium or a green roof system.

Applied via fully-bonded, hot-melt application.
