Balcony and terrace drain DN50/75 with articulated outlet and bituminous collar fi420mm, dry anti-odor flap, and round stainless steel grate cap. HL80HR

Terrace and balcony drainage – reliability and flexibility

This balcony and terrace drain, with a diameter of DN50/75, is a comprehensive solution for gravity drainage of water from balcony and terrace surfaces. Its design combines functionality, durability and ease of installation, making it an ideal choice for both professional installers and homeowners. Designed for effective water drainage, it provides effective protection against dampness and structural damage.

Tightness and adaptation to waterproofing conditions

A key element of this drain is a bituminous collar with a diameter of 420mm. This allows for a tight connection with the bituminous waterproofing layer, minimizing the risk of leaks and providing long-lasting protection against water. Thanks to this solution, the drain is an integral part of the waterproofing system, not just a water drainage element. In addition, the articulated outlet allows for adjustment of the outflow angle over a range of 90 degrees, which facilitates adaptation to specific installation conditions and the configuration of the balcony or terrace.

User comfort and material durability

The drain is equipped with a dry anti-odor flap, which effectively blocks unpleasant odors from the sewer, ensuring comfortable use of the balcony or terrace. The top with a round stainless steel grate not only looks aesthetically pleasing but is also characterized by high resistance to corrosion and mechanical damage. The adjustable grate height in the range of 20-70mm allows it to be adapted to the thickness of the structural layers of the balcony/terrace. A flow rate of 0.8 l/s guarantees effective water drainage even during heavy rainfall – the drain is designed to handle surfaces up to 26m2 with a typical rainfall intensity of 300 l/(sxha).

• Versatility: Possibility of use with various balcony/terrace layer systems thanks to available straight and collar extensions (HL340N, HL85N, HL85NH) and a drainage ring (HL180).
• Heating option: Compatible with the HL82 heating kit – an ideal solution in regions prone to frost.
• Durable materials: Made of high-quality polypropylene (PP) and polyethylene (PE), which ensures resistance to weather conditions and long-term operation.
• Easy installation: Articulated outlet facilitates installation in various configurations.
• Aesthetics: Round stainless steel grate adds elegance and a modern look.
