Triflex holds a large portfolio of projects that showcase the durability and versatility of its car park waterproofing systems. From airport expansions to shopping centre refurbishments, these five projects demonstrate how Triflex waterproofing systems rise to the challenge - whatever the conditions.

Manchester Airport Terminal 2

Manchester Airport invested £1bn to expand Terminal 2 and increase passenger capacity from 27 million to 55 million annually. As part of this development, a new 3,800-space car park was planned, with phase 2 originally set for completion in November 2019 but fast-tracked to April 2019. However, delays meant waterproofing couldn't start until winter, ruling out many other cold liquid applied systems that require warmer, dry conditions.

The chosen solution had to meet EN 1504-2 standards, offering long-term durability, dynamic crack-bridging performance, and safety for high traffic use. Mike Thelwell Flooring Ltd. proposed the Triflex ProPark^® system, a waterproofing solution suitable for application in winer temperatures as low as 0°C at the details, thanks to its PMMA technology. The resin cures within an hour, allowing for quick progress even in short, dry weather windows. 

Additional features included emery aggregate for improved ramp traction, contrasting colours to visually separate parking and driving areas, and durable line markings using Triflex Preco Line 300 and Triflex Cold Plastic to clearly indicate bays, routes, and pedestrian walkways.

Bath Podium Car Park

The Bath Podium Car Park, originally built in 1972, underwent a significant refurbishment to modernise its structure, improve safety, and future-proof its design. Central to the project was extensive structural repair to support the Hilton Hotel above, alongside enhancements to layout, security, and fall prevention. 

Triflex, working with Makers Construction Limited, tackled challenges posed by varying concrete quality and structural complexity, including reinforced concrete waffle slabs and steel-framed areas. A tailored solution was implemented: Triflex DeckDefence and Triflex DeckFloor Ramp for internal decks and ramps, Triflex ProTerra Buried for the podium, and Triflex StairCoat for stairwells. All systems were cold liquid applied, supporting the sustainable goals of the project, which also included LED lighting, PV panels, and EV chargers. The robust Triflex systems provided high durability, anti-skid finishes, and chemical resistance, while allowing for future adaptability in line with evolving EV infrastructure. 

With improved safety features like high-visibility nosings and long-lasting surface markings, the refurbishment not only preserved the car park's structural integrity but also elevated its functionality and sustainability for years to come. Read more about this project.

Buttercrane Shopping Centre, Newry

Triflex played a key role in the refurbishment of the Buttercrane Shopping Centre’s multi-storey car park in Newry, Northern Ireland. The nine-storey, 620-space facility not only wanted to  modernise the parking and entrance zones with a better aesthetic, but also address deck repairs, waterproofing and increase the number of electric vehicle charging points

Following a detailed site survey and condition assessment, Triflex proposed a tailored solution using their cold liquid-applied waterproofing and surfacing systems. For internal levels and ramps, Triflex DeckCoat was specified - offering fast-curing application, anti-skid properties, and excellent durability under heavy traffic. For areas located above occupied retail units, Triflex DeckFloor was used. This heavy-duty system provides dynamic crack bridging for high risk areas as we as high levels of slip and skid  resistance.

Both systems allowed for customisation in terms of colour and markings, improving wayfinding and giving the car park a modern, clean look. Importantly, Triflex’s rapid-curing PMMA technology enabled the car park to remain operational during the refurbishment, minimising disruption to businesses and visitors, which was vital due to the single access route.

The project was carried out by Triflex Authorised Contractor Larsen Contracts Ltd, ensuring expert installation. The completed works not only enhance the user experience and aesthetics but also ensure long-term structural protection and safety. Read more here.

Gateshead College Baltic Campus

Gateshead College faced significant issues with its multi-storey car park due to a failing coating on the upper decks, resulting in concrete damage and water ingress. The structure, which included a heating loop to combat snow and ice, required a reliable, long-term waterproofing solution that could meet strict deadlines and provide robust protection. 

Triflex conducted detailed surveys and testing, recommending their BBA-certified Triflex ProPark system, designed specifically for high-movement composite car parks. The system offers excellent dynamic crack bridging, chemical resistance, and durability. Following the removal of the existing coating and surface preparation, Triflex ProPark was applied across the 1,900m² area, with Quartz and Emery finishes used to maximise anti-skid performance. Additional Triflex products were used on upstands, penetrations, and stairwell roofs to ensure full waterproofing. The system cured quickly and was colour-coded for wayfinding, while the final markings delivered a crisp, clean finish. 

All work, completed to a high standard by Mike Thelwell Construction Ltd with Triflex’s support, met the college’s tight schedule and funding requirements, while offering a secure, long-term warranty for peace of mind. Read more about this project.

Middleborough Car Park, Colchester

Triflex played a key role in the successful refurbishment of Middleborough Car Park in Colchester, a five-storey, 12,000m² structure built in 1979 to serve The Octagon Centre. After decades of use, the car park showed significant deterioration, including delamination of previous coatings and water ingress

Working alongside Makers Construction Ltd, Triflex provided a comprehensive waterproofing and surfacing solution tailored to the structure’s needs. Following extensive concrete repairs, locally reinforced Triflex DeckFloor, a rapid-curing PMMA-based system, was installed to the exteanl deacks and ramps, offering durable, waterproof, and flexible protection against future wear and environmental exposure. Triflex DeckDefence, a cost-effective hybrid epoxy system, was installed on the internal decks to provide strong, slip-resistant surfacing. Heavily trafficked internal ramps were finished with Triflex DeckCoat with Emery, delivering long-lasting anti-skid properties.

To complete the refurbishment, Triflex’s cold-applied line marking systems enhanced the car park’s layout and visual clarity with custom colours and clear navigation aids. Read more here.

These case studies illustrate Triflex's expertise in delivering tailored, durable car park waterproofing systems across a diverse range of applications and projects.
