Balconies
Waterproofing balconies and terraces with SOPREMA ALSAN Liquid Waterproofing
Balconies and terraces are essential architectural elements that enhance the aesthetic appeal and functionality of residential, commercial, and industrial buildings. However, due to their constant exposure to varying weather conditions, these outdoor spaces are particularly vulnerable to water ingress, which can lead to structural damage, compromised safety, and costly repairs if not properly managed.
Effective waterproofing is crucial to ensure the longevity and durability of these areas, and SOPREMA ALSAN liquid waterproofing solutions offer a robust, versatile, and durable option for meeting these demands.


SOPREMA ALSAN
SOPREMA ALSAN liquid waterproofing systems are designed to provide seamless, flexible, and long-lasting protection against water penetration. These advanced solutions cater to a wide range of substrates and complex geometries often found in balconies and terraces, ensuring comprehensive coverage even in hard-to-reach areas. Unlike traditional waterproofing membranes that may require joints and overlaps, ALSAN liquid systems cure to form a monolithic membrane, eliminating potential weak points and significantly reducing the risk of leaks.
Critical Considerations
One of the critical considerations in waterproofing balconies and terraces is ensuring that the surface not only resists water penetration but also maintains anti-slip properties to guarantee user safety. This is especially important in wet conditions, where the risk of slips and falls increases. SOPREMA ALSAN systems can be tailored to meet specific anti-slip requirements through the incorporation of aggregate finishes and textured surfaces that enhance grip and stability.




Measuring Slip Resistance
To objectively measure the slip resistance of balcony and terrace surfaces, the pendulum test method, in accordance with BS7976-2, is widely recognised and utilised. The British Standard BS7976-2 outlines the procedures for conducting the pendulum test, which assesses the slip potential of flooring surfaces under various conditions. This method is highly regarded for its accuracy and reliability in determining the slip resistance of both dry and wet surfaces, making it an essential benchmark for safety compliance.
Why Choose SOPREMA ALSAN for Your Balcony & Terrace Projects
SOPREMA ALSAN liquid waterproofing systems are engineered to achieve excellent performance in pendulum test results, providing peace of mind that balconies and terraces will not only remain watertight but also safe for everyday use. The versatility of these systems allows for the adjustment of surface textures and the integration of anti-slip additives to meet or exceed the slip resistance values recommended by safety standards.
Incorporating SOPREMA ALSAN liquid waterproofing solutions into your balcony and terrace projects ensures a high level of protection against water ingress, structural degradation, and slip hazards. Their seamless application, adaptability to various surfaces, and compliance with rigorous safety standards like BS7976-2 make them a superior choice for both new constructions and refurbishment projects.
