Home > Companies > Triflex (UK) Ltd > DeckCoat - Car Park Deck Waterproof Coating System

System designed to waterproof and protect internal concrete car park decks over parking, and ground-bearing concrete car park decks and ramps. This totally cold-applied, fast-curing system offers significant installation advantages over rigid epoxy and polyurethane systems.

In combination with its waterproof, durable anti-skid wearing layer, the system can be used in conjunction with ETA-certified, reinforced, elastomeric and dynamic crack-bridging waterproofing for high risk areas, and BBA- and ETA-certified detail waterproofing.

Features and benefits:

  • Rapid installation: With a self-priming coating layer, subject to testing, the system can be applied in a simple, two-process application, saving time on site and increasing productivity.
  • Optional locally reinforced, elastomeric waterproofing membrane: The optional, locally applied reinforced membrane provides high tensile strength and long-term resistance to regular and unforeseen movement, cracking and flexural fatigue. The reinforced membrane has been tested for cyclic crack bridging up to 2 mm at -10°C.
  • Tough and durable: The system incorporates an aggregate-filled wearing course and heavy-duty seal coat designed for high-traffic, high-space change rate car parks.
  • High levels of anti-skid: With low slip potential in both wet and dry conditions, safety is maximized.
  • Totally cold, liquid-applied technology: With no risk from hot works, installation can be completed whilst the car park remains open to the public.
  • Rapid curing system – even at low temperatures: Works can be completed all year round, and critical areas can be completed overnight and opened to traffic the following day.
  • Maximum design options: With a wide range of standard and bespoke colours and finishes, there is no limitation in design.
  • Fully warranted.
  • CE-marked.
