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.

Description

Flexible, monolithic, elastomeric hot-melt bitumen waterproofing system for protected roofs, green roofs, terraces and podium decks.


Features and benefits:

  • Only a single application is required.
  • Robust and durable.
  • Flexible.
  • Root resistant when specified as a green roof (Graviflex (HM) cap sheet).
  • Self-healing.
  • Reinforced with a coated glass mesh for alkaline protection.
  • Permanently elastomeric.
  • Life expectancy for the service life of the roof in which it is incorporated.
  • Quick and easy to install - large areas can be covered quickly.
  • BBA certified.


Components:

  • Preparation: Langley Primer (HM).
  • Waterproof covering, first layer: Paratech R Reinforcement (0.11 kg/m²).
