Emergency Roof Drainage – Reliability and Safety

This emergency roof drain, designed for gravity drainage, is a key element in protecting the building from the effects of heavy rainfall. Its construction allows for effective water drainage in situations where the main roof drainage system is overloaded or malfunctioning. This solution is ideal for both professionals involved in the installation of drainage systems and building owners looking for additional protection against flooding.

The drain is designed to be installed as an independent installation draining water outside the main system, ensuring independent operation and minimizing the risk of failure of the entire system. Therefore, even in the event of problems with the main drainage, rainwater is effectively drained from the roof surface.

Construction and functionality

The drain has a spigot connection DN75/110 or a compatible compensation socket for HDPE welded systems. It is equipped with a self-regulating heating set powered by 230V, which prevents water from freezing in winter and ensures continuous drainage efficiency. In addition, the adjustable base height (in the range of 28-68mm) allows for precise adaptation to construction conditions and ensures optimal operation. The bituminous collar guarantees a tight connection with the roof waterproofing layers.

The use of polypropylene (PP) in the construction ensures durability and corrosion resistance. The weight of the drain is approximately 3.371 kg (data may vary depending on the source), which facilitates installation and operation. The drain grate with a diameter of 262 mm effectively stops leaves and other contaminants, preventing clogging of the system.

Benefits of use

• Emergency drainage: Provides an independent water drainage system in case of overload or failure of the main system.
• Adjustable height: Smooth adjustment of the base height (28-68mm) allows adaptation to different construction conditions and water build-up height.
• Freeze protection: Self-regulating heating set prevents water from freezing in winter, ensuring continuous drainage efficiency.
• Tightness: Bituminous collar guarantees a tight connection with the roof waterproofing layers.
• Durability: Made of high-quality polypropylene (PP), resistant to corrosion and mechanical damage.
• Easy installation: Compatible with popular spigot connections DN75/110 and HDPE welded systems.
• Clogging protection: The drain grate stops leaves and other contaminants, preventing system blockages.

Remember to select the appropriate additional elements (supporting or drainage rings) depending on the arrangement of the roof layers – classic, inverted or green – to ensure optimal tightness and functionality of the system.
