The connection flange ensures a tight connection with the waterproofing layer, minimizing the risk of leaks and structural damage.

Design and application

The HL81.1G drain is a solid solution for professionals and demanding users. Its construction based on a water trap guarantees effective water drainage, and the cast iron grate of class L15 (1.5t) ensures resistance to loads. The ability to adjust the grate height in the range of 30-75mm allows for perfect adaptation to the selected thickness of the roof structure. The swivel outlet (DN50/75) provides freedom in adjusting the direction of water flow to the specifics of the project.

• Tightness: The connection flange in combination with the HL83 sealing kit guarantees a completely tight connection with the waterproofing. This is crucial for protecting against moisture and damage to the building.
• Adjustment: Adjustable outlet angle (90 degrees) and grate height allow for precise adjustment of the drain to specific installation conditions.
• Durability: The cast iron grate of class L15 can withstand a load of up to 1.5 tons, making it an ideal solution for areas with high traffic.
• Flow rate: A drainage efficiency of 0.5 l/s ensures quick and effective water drainage even during heavy rainfall.
• Compatibility: Possibility of extension with additional elements (straight and flange extensions HL340N, HL85N, HL85NC, HL85NH) and heating set HL82 allows you to create a comprehensive drainage system tailored to individual needs.
• Resistance: The materials used in production are resistant to temperature (up to 85°C), ensuring long-lasting and reliable operation in various weather conditions.

Installation and additional information

Installation of the drain is simple and intuitive, especially when using dedicated sealing kits HL83. Thanks to this, both installers and end users can enjoy trouble-free use for many years. It is worth remembering the possibility of using additional system elements to optimize the operation of the entire roof drainage system.
