Triflex BBA and UKCA certification

Trilfex ProTerra is formulated for waterproofing walkways, balconies and terraces over occupied spaces. It will reliably waterproof and protect the structure as well as look good for years to come.

The BBA certified Triflex ProTerra delivers a combination of reliable, long term waterproofing, highly durable surfacing and attractive design. The system is ultra-fast curing and cold liquid applied, allowing installation to be completed quickly, without the use of hot works, and with minimal impact on users.

With 4 system variants, over 50 standard colours and bespoke colours on request, the system can be tailored to the project. And for a truly unique finish, a range of stencils and motifs are available with Triflex Creative Design.

System highlights

Crack bridging icon 99 x 99

Dynamic crack bridging, fully reinforced, cold applied system

Triflex lead from the front. Featuring unique resins with enhanced elastomeric properties and high tensile strength fleece reinforcement, we deliver a totally waterproof solution that can accommodate movement and cracking within the structure. There is no risk from hot works during installation as all Triflex materials are applied in a totally cold liquid form, curing to create a waterproofing membrane solution that lasts.

Rapid installation fast curing icon 99 x 99

Fast curing with rapid installation

Rapid curing and easy to install, Triflex allows buildings to remain occupied during installation, limiting access restrictions and unnecessary disruptions to everyday life. Installation can be carried out all year round, and the majority of system variants still cure quickly at temperatures down to 0°C.

Save money icon 99 x 99

High levels of protection with a low lifecycle cost

The system performance is unaffected by ponding water and the system is resistant to chlorides (salts), carbon dioxide ingress, and approved de-icing and cleaning products.

The heaviest duty variant, Quartz Design with large grain quartz offers a robust solution for highly trafficked applications including local authority access walkways and permanent pedestrian traffic routes. With proven, long term performance Triflex ProTerra offers best value with a low lifecycle cost.

Asphalt overlay icon 99 x 99

Asphalt overlay

Many balconies, walkways and terraces have historically been waterproofed using asphalt which over time will fail. Triflex has more than 30 years’ experience of asphalt overlay in the UK, Triflex ProTerra is the ideal solution for directly overlaying failing asphalt to trafficked areas. In fact, whatever the substrate, we can provide a quick, easy and reliable overlay solution.

Environmental safety icon 99 x 99

Safety and environmental

The solvent and isocyanate free resin technology has been assessed under BREEAM principles and can contribute to A+ ratings. The levels of skid resistance of a number of the finish variants make these particularly suitable for high risk, frequently trafficked areas.
