Triflex system certifications

The most important part of any roof is the waterproofing system as without an effective and long lasting solution the building is vulnerable to water ingress and the risk of damage to the building fabric.

The BBA and ETA certified Triflex ProTect is an ultra versatile, highly durable roof waterproofing solution, suitable for both refurbishment and new-build, and is compatible with almost all roof build-ups and existing substrates, including single ply. Even difficult applications such as zero pitch roofs and areas that are subject to standing or ponding water pose no problem as the system does not break down under immersion in water. It is exceptionally fast curing and totally cold liquid applied, allowing installation to be completed quickly, without the use of hot works and at any time of year. With a long term proven track record and the highest levels of certification and testing, Triflex ProTect sets the standard for roof waterproofing.

Versatility and compatibility

Whether for refurbishment or new-build, Triflex ProTect is suitable for virtually all roofing applications. The significant costs, risks and disruption associated with removal of the existing membrane can be eliminated as the system is compatible with, and can be used to overlay almost all roof substrates. Even failed single ply and other membranes such as EPDM can be overlaid. Roof waterproofing made easy

Cold applied, fast curing with rapid installation

Rapid curing and easy to install, Triflex allows buildings to remain fully occupied during installation, limiting access restrictions and unnecessary disruptions to everyday activities. Installation can be carried out all year round and the system still cures quickly at temperatures down to 0°C. Being rainproof in just 30 minutes weather windows can be maximised and down time minimised. There is also no risk from hot works during installation as all Triflex materials are applied in a totally cold liquid form, curing to create a solution that lasts

Single process application

Installation time and costs are significantly reduced when compared to multi-coat, typically solvent based systems. The single process application also eliminates the risks of inter-layer adhesion issues

Self-terminating icon 99 x 99


With Triflex there is no need for termination bars as Triflex systems are fully self-terminating. By forming such a strong bond with the substrate, and thanks to its flexibility and fleece reinforcement, the system leaves no opportunity for water to permeate

Fully reinforced technology

The unique, highly flexible Triflex ProTect resin is used with a special high tensile strength polyester fleece to ensure that high levels of movement and cracking within the structure and between substrates can be accommodated. Proven fully reinforced waterproofing technology that stands the test of time

Tried and tested

Triflex ProTect offers a complete waterproofing solution that will last for years to come. The system is not only certified and tested to the highest UK and European standards, it has also been successfully installed for more than 20 years in projects across the globe. Triflex ProTect was the first liquid applied waterproofing system to be certified under ETAG 005 and was the first product of its type to be CE marked in Europe

Durability icon 99 x 99

Tough and durable protection

The standard Triflex ProTect system is designed for foot traffic and provides exceptional puncture resistance when compared to many alternative materials. With the option to include a heavy duty wearing layer, even the most heavily trafficked industrial roofs can be securely waterproofed and protected from damage
