Interface solutions for secure detail waterproofing and connection details
Detail and joint areas are among the most common weak points in building waterproofing. Differences in materials, movement, and loads can quickly lead to leaks, cracks, and consequential damage in these areas.
Triflex offers tested interface solutions based on liquid polymer (PMMA) —precisely tailored to building components, substrates, and adjacent systems.
The result: permanently watertight, code-compliant, and system-compatible detail waterproofing.

Planning Certainty for Complex Connection Details
In day-to-day planning, standards (e.g., DIN), system specifications, and actual site conditions all come into play.
Particularly critical areas include:
- Roof connections and parapets
- Balcony and terrace connections
- Parking garages and underground parking garages
- Expansion joints
- Door and window connections
- Green roof connections
The challenge: Each interface only works if all components interact seamlessly.
Solution with Triflex: Tested system details minimize room for interpretation and ensure:
- clear design specifications
- reliable execution on the job site
- minimized risk of consequential damage

System Compatibility as a Key to Success
Errors often do not originate in the product itself—but at the interface between systems.
Triflex liquid polymer systems are specifically designed to work with adjacent components, such as drainage systems, joint profiles, or window flashings.
In concrete terms, this means:
- tested connection details instead of solutions from individual trades
- defined transitions between materials
- reliable integration of expansion joints
- durable adhesion even on complex substrates
Your benefits:
- Planners: areliable basis for bidding and detailed planning
- Contractors: Clear specifications = fewer errors on the job site
- Investors: Lower risk of damage and liability















Greater planning reliability for complex interfaces—from roofing to civil engineering.
Triflex Detail and System Finder
Does your project have specific waterproofing requirements? Triflex offers the right system for every detail—permanently watertight, technically tested, and optimally coordinated. Our waterproofing solutions are top-rated, have a long track record of proven performance, and are continuously refined. This ensures planning reliability, code-compliant installation, and long-lasting functionality—from design through completion.

Joint areas connect different materials and components. Movement, temperature changes, and moisture all act on these areas simultaneously. Without properly designed systems, cracks and leaks can quickly develop.
Liquid plastic is particularly well-suited for complex connection details, penetrations, and transitions. It offers clear advantages whenever multiple materials meet or a simple seal is not possible.
Typical applications include window flashings, balconies, roofs, and structural penetrations.
Much of the damage occurs at the interfaces between different trades. When materials are incompatible, liability issues arise. Tested interface solutions prevent precisely this risk.
Standardized, tested details provide clear guidelines for planning and construction. This reduces room for interpretation and minimizes sources of error on the construction site.
Individual products often solve only part of the problem. System solutions take all interfaces into account and ensure a comprehensive solution that works reliably over the long term.
For all critical transitions, such as roofs, balconies, parking garages, window flashings, expansion joints, and green roofs.
