Triflex ProPark

Fully reinforced PMMA system for external decks and ramps above occupied premises and those at high risk of cracking

Triflex system certifications

Exposed, rooftop car park decks and ramps directly above occupied spaces are essentially highly trafficked roofs and it is therefore vital that they are fully waterproofed to protect the structure and contents below. For new build and other structures, particularly those with significant levels of structural movement and cracking the priority may be more to protect the structure from the damaging ingress of chlorides and other environmental influences. Whatever the requirement, if left untreated or with insufficient protection, water ingress and other corrosive elements can result in damage to the building fabric and contents.

Engineered to offer long term protection, even in the toughest of circumstances, the BBA and EN 1504-2 certified Triflex ProPark not only prolongs building life but also answers all of your waterproofing, surfacing, safety, aesthetic and design needs. The heavy duty, dynamic crack bridging system is certified to the highest standards, and with a proven track record in the UK and across Europe, ensures long term security and peace of mind.

System highlights

Crack bridging icon 99 x 99

Dynamic crack bridging, fully reinforced, cold applied system

Triflex are the car park waterproofing and surfacing experts. Featuring unique resins with enhanced elastomeric properties in combination with high tensile strength reinforcement, we deliver a totally waterproof solution designed specifically to accommodate the movement and cracking within parking structures. There is no risk from hot works during application as all of our materials are installed in a completely cold applied form, quickly curing to create a solution that lasts.

Durability icon 99 x 99

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 ProPark 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.

Asphalt overlay icon 99 x 99

Asphalt overlay

Historically many car parks have been protected with traditional asphalt coverings which over time will fail. With more than 35 years’ experience of directly overlaying in excess of 2 million m² of failed asphalt car parks, Triflex are the industry experts and Triflex ProPark is the industry leading solution for asphalt car parks over occupied premises. In fact, whatever the substrate, Triflex can provide an overlay solution that performs and lasts. Download your copy of the Triflex Asphalt Overlay Infographic here.

Tried and Tested

Triflex ProPark offers a complete waterproofing and surfacing solution for refurbishment and new-build projects that will last for years to come. The Triflex ProPark system is not only certified and tested to the highest UK and European standards, but has an outstanding track record based on the use of our reinforced waterproofing technology for car parks for more than 30 years in projects across the globe.

Rapid installation fast curing icon 99 x 99

Rapid curing

Exceptionally fast curing, Triflex enables 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. Ramps and critical areas can be completed overnight and opened the next morning.

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.

Environmental safety icon 99 x 99

Safety and environmental

Our solvent and isocyanate free resin technology has been assessed under BREEAM principles and can contribute to A+ ratings. To minimise environmental impact the majority of the resin components are also supplied in recyclable bulk containers. The system is compatible with virtually all substrates allowing the existing failed or failing membrane (including asphalt) to be directly overlaid instead of being removed, significantly reducing waste, time, cost and impacts on landfill.
