Triflex works within the B2G Open Framework, giving public sector clients a fast, compliant route to procure full-system flat roofing solutions across the UK. The framework supports any property type and project scale, with options for direct award or mini‑competition. It operates with a transparent 1% levy and no hidden fees.
Key features
- Fully compliant with UK procurement regulations
- Direct award capability for rapid mobilisation
- Usable by any contracting authority, anywhere in the UK
- Fully adjustable weighting to support value for money
- Simple, streamlined project registration and delivery process
Dynamic Consortia Model
The framework can be used with a Dynamic Consortia Model, allowing Triflex to assign each project to the most suitable approved contractor via the B2G DPS. This ensures clients benefit from manufacturer-led design and warranty assurance, while a vetted contractor handles on‑site delivery
This model provides:
- Access to the right contractor for every project, as DPS members can join at any time
- Reduced procurement overhead and greater flexibility than fixed consortium arrangements
- Integrated delivery assuring optimum efficiency and compliance
Advantages at a glance
Sustainable overlay solutions
Triflex liquid waterproofing membrane systems can be used to overlay virtually all existing substrates saving the associated time, costs and disruption.
With over 7,000 substrates tested, the Triflex systems exhibit high levels of compatibility meaning that the implications on landfill of the removal of existing waterproofing systems can be negated. A more sustainable refurbishment option becomes a practical, cost effective solution with long term proven performance and warrantied result.
