CE and UKCA logos

The majority of multi-storey car parks feature internal concrete decks and ramps over parking or ground bearing concrete decks and ramps. While these areas are generally not exposed to the same external weather influences as exposed decks, they are generally subject to significantly higher high levels of chloride contamination and abrasion through traffic. Studies have shown that the worst degradation to the reinforcement in car park structures typically occurs on the lower levels and lower ramps of car parks.

It is essential that these decks and ramps are waterproofed, surfaced and protected to ensure the structure is not compromised, and Triflex DeckCoat is the perfect solution. The system features our unique, ultra-fast curing PMMA resin technology that offers significant installation advantages over rigid epoxy, polyurethane and polyaspartic systems. In combination with the waterproof and durable anti-skid wearing layer, the system can also include a reinforced, elastomeric and dynamic crack bridging waterproofing membrane for high risk areas.

Rapid installation

With a self priming coating layer (subject to testing) the system can be installed in a simple, two process application, saving time on site and increasing productivity.

Optional locally reinforced, elastomeric waterproofing membrane

Even high risk areas pose no problem for this durable solution, as the system can incorporate a fully reinforced, localised waterproofing membrane designed specifically to accommodate the dynamic movement and cracking within parking structures.

Tough and durable protection

The demands of even the highest trafficked, highest space change rate car parks are no issue for the highly traffic, impact and load resistant wearing layer and durable surface finish used in the Triflex DeckCoat system. The system is unaffected by ponding water and is resistant to chlorides (road salts), carbon dioxide ingress, petrol, diesel, brake fluid, engine oil, battery acid, and de-icing and cleaning products. Protection that's built to last, with a low lifecycle cost.

Rapid curing, cold applied system

Exceptionally fast curing, Triflex systems allow car parks to remain open during installation, limiting access restrictions and unnecessary disruptions. Installation can be carried out all year round and the system still cures quickly at temperatures down to 0°C. There is no risk from hot works during installation as all Triflex materials are applied in a totally cold liquid form, quickly curing to create a solution that lasts.

Anti-skid icon 99 x 99


The system offers high levels of long-term skid resistance in wet and dry conditions, providing a secure and safe solution for both vehicles and pedestrians.

Safety and environmental

Our solvent and isocyanate free resin technology has been assessed under BREEAM principles and can contribute to A+ ratings, and to minimise environmental impact the majority of the components are supplied in recyclable bulk containers.
