Durable Renovation of Existing Balconies, Pergolas, and Roofs
Solutions for Housing Associations
Residential buildings present unique challenges in terms of planning and construction. Triflex offers proven solutions for waterproofing and repairing heavily used surfaces—solutions that can be efficiently implemented even while the building remains in use.
Reliably waterproof balconies, patios, and roofs—for long-term protection against moisture
Leaky balconies, patios, or roofs can lead to moisture damage in buildings. For example, water can penetrate the structure through connections, joints, or cracks. Possible consequences include moisture damage, mold growth, and damage to the building’s structure, which may require remediation measures.
A professionally applied liquid polymer waterproofing system provides long-term protection for these critical areas against moisture intrusion.
Triflex PMMA-based waterproofing systems are applied in liquid form and adhere fully to the appropriate substrate. This creates a seamless and joint-free waterproofing membrane that adapts even to complex details and connections.
For you as a building owner, this means:
- reduced risk of moisture-related consequential damage
- greater planning certainty for maintenance and renovation
- a contribution to the long-term preservation of the protected building structure
The systems are suitable for both new construction and the renovation of existing buildings, even in cases involving complex details such as door junctions, railings, or penetrations.

Typical Applications in Existing Housing Stock
Balconies, pergolas, and roof surfaces are among the areas of a residential building that are subject to the most wear and tear. They place high demands on waterproofing, safety, and durability.
