Description
A high-performance waterproofing membrane designed for reliable, long-term protection in demanding construction environments.
This flexible membrane is completely waterproof and vapour-retarding, providing a secure barrier against moisture ingress in both internal and external applications. It is fleece-coated on both sides to ensure excellent adhesion within bonded waterproofing systems and is highly resistant to tearing, ageing, and chemical exposure.
The integrated 10 cm cutting grid allows for fast, accurate, and efficient installation on site, while its flexible structure makes it ideal for use on both walls and floors, including areas with underfloor heating. For optimal bonding, application with a 3 mm or 4 mm notched trowel is recommended.
Engineered for durability and performance, SUBSTRAT Waterproofing Membrane is also alkali-resistant and meets high environmental standards, making it suitable for sustainable construction systems.
