Connecting made easy
Revisable branch channels from the company Richard Brink for every installation location.

Branch channels create a very specific dewatering channel that directs rainfall, for example, from drainage troughs to roof outlets. However, integrating these channels into existing dewatering systems tends to be less than optimal due to a lack of fixed connections. Richard Brink offers a solution to this problem with its Subterra branch channel system made of aluminium. This system is one of the first revisable branch channels on the market. Connected via an adapter, it can easily be attached to any channel produced by the metal products manufacturer at several points along the entire lateral section of the branch channel. Moreover, the sophisticated clip system guarantees quick and easy installation. Using clip connectors, technicians can extend the length of the branch channels and troughs as required and easily add elements such as inspection shafts to the installation.

Branch channels installed onto a green roof space direct this excess water under the planting soil and drainage layers to the nearest outlets. Rainwater on roof terraces and balconies is similarly directed from the loose material down under the surface area and on towards the drain. Branch channels are usually attached to the drain slots in the dewatering channels within the drainage layer. However, there is no firm connection between the channel body and branch channel, meaning rainwater does not always flow into the installed channel. The innovative branch channel system Subterra from the company Richard Brink is on hand to solve this problem.

Simple connection
The solution to the problem lies in the drainage troughs manufactured by the company: pre-perforated cut-out sections allow the trough to be connected at different points. An adapter that fits into the opening serves as a connecting piece for the aluminium branch channel. The integrated dirt trap also prevents leaves, dirt and loose material from making its way into the system. As the Subterra system is especially suited to green roofs, this feature also ensures reliable dewatering in the long term.

Just clip in
Thanks to its intelligent clip system, the channel can be installed in just a few easy steps. The company Richard Brink manufactures the branch channel in a standard length of 3 metres. This can however be extended using connectors depending on the installation location. Side branches and curves are also manageable without the need for additional resources thanks to T-pieces and corners in 90° and 30° angles. However, the user is not restricted to the standard models here: cut in half along the perforation lines, 90° corners are made into 45° and 30° to 15° corners. Inspection shafts lend themselves particularly well to visual inspections of the drain. They are also integrated into the branch channel system and feature cut-outs on three of their four sides where branch channels can be attached. The 100mm high shafts can optionally be raised by 50mm and 100mm using stacking elements. In future, Richard Brink will also offer gullies that can be connected to its branch channels.

Perfectly combined
The time-proven Stabile drainage trough is also offered by the metal products manufacturer in a special design featuring pre-perforated cut-out sections that can be combined with the Subterra system. Upon request, all troughs produced by Richard Brink can be adjusted specifically for this application in a standard design height. Richard Brink is thus able to fulfil every need here, irrelevant of installation location or visual appearance.
