Triflex holds a large portfolio of projects that showcase the durability and versatility of its car park solutions. Delivering professional and high-quality outcomes across the UK, here are some standout case study examples.
Swan Walk, Horsham
The 900-space Swan Walk car park supports a busy shopping centre attracting 6.7 million annual visitors, offering 24/7 town centre parking for shops, bars, and restaurants. Built in the 1970's, Horsham District Council sought a waterproofing, surfacing, and protection system for the external deck as part of its long-term maintenance strategy.
Following the removal of a damaged coating by another party, Triflex UK and Rateavon tackled the exposed concrete on the top deck. The screed was in poor condition, with visible water ingress and heavy scoring across the surface.
The team performed adhesion and cohesive strength tests to identify the best solution. After hammer testing across level 4, all failed screed was removed and replaced with rapid-curing concrete repair material, preparing the surface for the Triflex waterproofing system. Triflex recommended their Triflex DeckFloor with Emery to strengthen and smooth the damaged surface - delivering a robust, long-lasting finish tailored to the site’s needs.

Patriotic Street, Jersey
Built in the 1980’s, the 12-storey Patriotic Street car park in Jersey provides 750 spaces for the town centre and nearby hospital. As part of its 15-year maintenance cycle, the waterproofing and surfacing was recently refurbished. Triflex systems - first installed 15 years ago - were used again for their proven durability. Working with authorised contractor CRL, The in situ Triflex system remained fully bonded to the underlying asphalt, meaning that a further overlay could be achieved, enabling a time, and cost saving overlay rather than full removal.
For the top-level decks, Triflex ProPark® was applied, offering long-term dynamic crack-bridging protection and a 15-year BBA-certified life expectancy. Internally, high-traffic ramps and aisles were upgraded with Triflex DeckFloor with Emery for its wear resistance and anti-skid finish. Parking bays were left untouched, still performing well.
Thanks to Triflex’s cold-applied, fast-curing technology, work was carried out with minimal disruption, often overnight. The bright colour scheme was retained and enhanced to improve wayfinding. The refurbishment avoided hot works or strip-out, supporting Jersey’s sustainability aims. Read more about this project.
Marsland House, Greater Manchester
Marsland House in Sale, Greater Manchester, required a robust waterproofing and surfacing solution for its external car park deck and ramp. After initial perimeter waterpoofing five years prior, phase two was to waterproof and surface the main car park deck area with a Triflex system to address extensive coating failures.
The car park, made up of two types of concrete construction, had delaminating coatings, cracking due to movement, and a leaking drainage channel. Triflex Field Technicians assessed the site, recommending the Triflex DeckFloor system - a flexible, heavy-duty waterproofing solution with fully reinforced, localised waterproofing membrane with dynamic crack-bridging capabilities. Old coatings were fully removed due to poor condition, and loop joints were added to accommodate structural movement. Drainage channels were modified and lined with Triflex ProDetail to prevent future leaks.
Despite challenging autumn weather, the authorised contractor, Grade 2 Structural Repairs, completed the work efficiently thanks to Triflex’s rapid-curing PMMA resin technology. The result is a durable, watertight, and visually improved car park that enhances both the safety and appearance of the Marsland House premises. Read more about this project.
The Royal Derby Hospital
Ten years after its initial construction, the waterproofing system at The Royal Derby Hospital car park had come to the end of its warrantied life. Given its role as a first point of contact for many visitors, upgrading the car park was vital for both safety and the hospital’s image.
Managed by Skanska under a PFI contract, a solution was needed that offered minimal disruption and long-term protection. Triflex ProPark was chosen for its cold liquid application, solvent-free formula, and rapid curing, enabling fast and safe installation. The refurbishment was scheduled for the quieter summer months.
A site survey revealed severe wear and splitting of the existing waterproofing, requiring its complete removal. Although this temporarily exposed the structure, the Triflex system's quick curing time mitigated weather risks. The new solution includes a reinforced membrane designed to handle structural movement and prevent cracking. Triflex also supplied durable markings and signage.
Concrete Repairs Limited, the contractor, praised the system’s ease of application and ability to complete sections quickly, even around complex details like ticket machines and safety barriers, ensuring comprehensive waterproof protection. Read more about this project.
Preston Bus Station
In 2016, Triflex was invited by Makers Construction Limited to deliver a waterproofing and surfacing solution for the multi-storey car park at the Grade II-listed Preston Bus Station, which was undergoing major restoration. Built in the 1960s and once Europe's largest car park, the structure required modernisation while preserving its iconic design.
The project involved treating an over 12,000m² area across exposed and internal decks, with the latter located above an active bus depot - demanding an overlay solution. Triflex DeckFloor was specified due to its ability to overlay the existing worn asphalt substrate directly, avoiding disruption and reducing costs. The system offers high durability, chemical resistance, and excellent anti-skid properties, making it ideal for busy car parks. For ramps, Triflex DeckFloor ramp systems were used, incorporating emery for enhanced grip. Pre-installation preparation included removing clustered blisters and shot blasting the decks.
As a cold-applied and fast-curing system, Triflex DeckFloor enabled a staged, efficient installation that kept the car park operational and minimised public disruption. Read more about this project.
Victoria Shopping Centre
Triflex was called to The Victoria Shopping Centre in Southend-on-Sea by Workman LLP to inspect and assess the condition of car park decks above the centre and a retail outlet. The 1,400m² area featured an ageing asphalt waterproofing system that had become cracked and was letting water ingress into the outlet below.
Triflex’s inspection revealed a soft, bitumen-rich surface layer lacking coarse aggregate, causing surface defects like tyre marks and ruckling. Due to these findings, Triflex was specified for the project, and their Authorised Contractors, Makers Construction Ltd, used the Triflex ProPark system to overlay the failing asphalt. The system was chosen for its proven durability, seamless finish, and dynamic crack-bridging properties, making it ideal for exposed decks. Additional detailing was carried out using Triflex ProDetail and Triflex ProFibre systems to waterproof around air conditioning units and plant areas. All products were cold-applied, solvent-free, and certified to the highest safety and performance standards.
The project was delivered on schedule, and Triflex has since been invited to provide further specifications for other areas of the site. Read more about this project.
ASDA Liverpool
The Asda car park in Huyton, Liverpool, with its 3,000m² space, was suffering from significant wear and tear due to years of heavy traffic and exposure to the elements. The asphalt had developed cracks, blisters, wheel indentations, and ruckling, leading to water penetration and posing safety risks for pedestrians and vehicles. The surface also lost its anti-slip properties, especially in wet conditions.
Initially, only the most damaged areas were to be repaired, but after a thorough survey by Triflex, it was determined that the entire car park required refurbishment for better protection and an improved finish. The Triflex DeckFloor system, a high-performance waterproofing solution, was chosen for its ability overlay asphalt surfaces and provide a durable wearing layer.
To minimise disruption, the works were completed in phases, ensuring the car park remained operational, with the fast-curing system allowing for quick reopening. Despite poor weather, the system's rapid curing even at low temperatures ensured that the project stayed on track. Read more about this project.
Trinity Square, Nottingham
At Trinity Square Car Park, a recurring issue involved static electric shocks caused by vehicles generating electrostatic charges on high-resistance surfaces like traditional asphalt. In dry conditions, these charges can linger and discharge when a driver touches a grounded object, such as a ticket machine. Previously, water was used to mitigate this through a drip system, but it caused slip hazards and water ingress issues.
The solution was the installation of Triflex DeckFloor Anti-Static, a cold-applied, conductive waterproofing and surfacing system. The process involved fitting a copper pad and earth wire into the substrate, sealed with Triflex Cryl Paste. The surface was then layered with a conductive primer, resin, aggregate, and finish. This anti-skid, waterproof system effectively disperses electrostatic charges while being quick to install and safe to apply, thanks to its cold curing.
The entire installation was completed overnight, avoiding disruption in the busy city centre. The result has been a noticeable improvement in user safety and experience, both at Trinity Square and other car parks facing similar challenges. Read more about this project.
