High-performance fabrics for liquid membranes
Customized solutions for secure liquid applied waterproofing systems
Waterproofing is one of the most critical challenges in the construction industry. Damage to external horizontal surfaces – for example, due to concrete settling or material aging – can lead to water infiltration and cause serious harm to balconies and terraces. To address these challenges, Freudenberg Performance Materials has developed advanced solutions for liquid-applied waterproofing systems. We offer a wide range of liquid waterproofing solutions based on different technologies, supported by expert technical assistance to ensure optimal performance and customer satisfaction.

Why are liquid membranes with nonwoven inlays a modern type of roof waterproofing?
Liquid membranes, also known as liquid-applied waterproofing systems, are a modern and highly versatile solution for sealing and protecting roofs. Thanks to their seamless application and strong resistance to weather conditions, they are increasingly used in both residential and commercial construction. Key application areas and benefits include the following:
1. Flat roofs
Liquid waterproofing is especially effective for flat roofs, which are more susceptible to water pooling. Traditional roofing materials often have seams or joints that can become vulnerable over time. Liquid membranes, however, form a seamless, flexible membrane that fully adheres to the surface, ensuring excellent waterproofing even for complex roof structures.
2. Roof renovation and repair
Liquid membranes are ideal for restoring old or damaged roofs without the need for complete removal. They can be applied directly over existing materials such as bitumen, metal, concrete, or asphalt, saving both time and cost.
3. Green roof systems
Due to their root resistance and durability, liquid membranes are also used as the base waterproofing layer in green roof constructions. They prevent water penetration while supporting the planting of rooftop vegetation.
4. Complex roof structures
Roofs with multiple penetrations, skylights, or irregular shapes benefit from liquid membranes, as they easily conform to all forms and details, creating a continuous seal around pipes, vents, and edges.
5. Balcony and terrace waterproofing
In addition to roofs, liquid membranes are often applied on balconies and terraces where reliable waterproofing is essential. Once cured, they form a walkable surface, and some systems even allow for decorative finishes.
In a nutshell: Liquid waterproofing systems are a highly adaptable and long-lasting solution for protecting roofs and other surfaces. Their ease of application, combined with strong performance characteristics such as UV resistance, flexibility, and crack-bridging capabilities, makes them an ideal choice for modern construction and renovation projects.
