Home > Companies > Triflex (UK) Ltd > AWS - Car Park Waterproofing System with Asphalt Wearing/ Load Bearing Layer

A heavy-duty, thick layer, fully reinforced waterproofing and surfacing system for vehicle service decks over occupied premises and high-risk service decks subject to significant structural movement and associated cracking.

The Triflex service deck waterproofing solution combines fully reinforced asphalt overlay technology with resins designed to be overlaid with a sacrificial wearing course at up to 250°C. The build-up has been proven on high-use UK shopping centre service decks for more than 15 years, and allows the asphalt to be used solely as a sacrificial wearing layer.

Features and benefits:

  • Fully reinforced waterproofing membrane: Unique technology provides the system with high tensile strength and long-term resistance to regular and unforeseen movement, cracking and flexural fatigue.
  • Asphalt overlay: Proven performance in overlaying failed or failing asphalt build-ups, avoiding the risks, costs and disruption associated with removal.
  • Tough and durable: Long-term durability with a sacrificial wearing layer designed solely to deal with shear forces, impacts and to protect the underlying waterproofing.
  • Phased completion: Areas can be completed section by section with seamless continuity, allowing the service deck to remain open during works.
  • Heavy-duty markings: Heavy-duty markings can be applied to the asphalt, which maintain their visibility over time and are vital in ensuring the safe flow of traffic and pedestrians.
  • Fully warranted.
  • CE-marked.
