Safety Drainage Outlet - Horizontal

This safety Drainage outlet is a roof drain with a horizontal flange and roof membrane that can be used as safety drainage. The water is drained vertically from the flat roof and discharged horizontally through the parapet via the pipe, which has a slight slope.

Safe and efficient drainage for flat roofs

With increasing rainfall and climate change, greater demands are placed on roof drainage, especially on flat roofs. Here, safety drainage systems play an important role in preventing flooding and water damage. Our horizontal safety drainage outlet is designed precisely for this purpose:

A reliable solution that handles rainwater quickly and efficiently when the regular drainage system cannot keep up.

What is an horizontal safety drainage outlet

A horizontal safety drainage outlet differs from traditional outlets by combining vertical water collection from the roof surface with horizontal discharge through the parapet. This is achieved via an integrated pipe with a slight slope, ensuring natural fall and rapid water transport – even under extreme weather conditions.

The outlet is equipped with a horizontal flange that is welded to the roof membrane, providing a watertight and robust connection that will last for many years.

Product benefits

Our horizontal safety drainage outlet is designed to deliver maximum functionality with minimal complexity. It is particularly suitable for use on buildings with flat roofs and is compatible with most roof structures.

  • Horizontal flange for easy and secure integration with the roof membrane.

  • Vertical drain from the roof surface ensures rapid rainwater collection.

  • Horizontal discharge through the parapet directs water straight to open air.

  • Built-in slope in the pipe promotes natural flow and prevents blockage.

  • Ideal as emergency drainage, activated only when the primary drain is overloaded.

Safety and functionality

An effective safety drainage system is not only a technical necessity – it is also insurance against water damage, operational downtime, and high maintenance costs. With our horizontal safety drainage outlet, you get a solution that is automatically activated in case of water accumulation, without the need for mechanical parts or electricity.

When the roof’s regular drainage system reaches its capacity limit, the safety drainage outlet activates and directs the water away – out of the building’s structure and down to ground level or into the rainwater system, depending on the installation design.

Easy installation and long service life

The outlet is made from weather-resistant materials that ensure high durability, even under significant temperature fluctuations and UV exposure. It is delivered ready for installation, with a pre-set slope in the piping and standard dimensions that fit typical roof structures.

Installation only requires:

  • Securing and welding to the roof membrane

  • Connecting the horizontal outlet pipe through the parapet

  • Optional installation of a leaf guard or protective grille
