Roofing with bituminous collar HL85NH

Extension for gullies with bituminous collar

This element provides a practical solution for raising existing gullies and ensuring a watertight connection with the next bituminous layer. The HL85NH extension allows for precise height adjustment, which is crucial for adapting the installation to specific site and design conditions. This makes the installation process more flexible and tailored to needs.

Compatibility and application

The HL85NH extension is designed to work with a wide range of gullies manufactured by HL HUTTERER & LECHNER GMBH, including the HL70, HL80, HL90, HL300, HL304, HL310N and HL510N series. It also works well with HL340N, HL85N extensions and the HL180 drainage ring. This is a universal solution that can be used in both new installations and in the modernization of existing drainage systems.

• Height adjustment: Possibility of precise height adjustment by cutting off the element (total height 227mm). This makes it easier to adapt to the existing surface.

• Watertightness: The bituminous collar provides a reliable seal for the connection with the bituminous layer, minimizing the risk of leaks and water infiltration.

• Durability: Made of high-quality materials resistant to weather conditions and mechanical loads – a guarantee of long-term use.

• Easy installation: Simple construction and compatibility with popular gully series make the installation process easier and faster.

For installers, this means saving time and costs associated with adapting elements and ensuring solid workmanship. For the end user – a reliable drainage system that protects against the effects of precipitation and ensures safe use.
