Aluminum channeling SUBTERRA

for drainage systems

revisable branch channel clever clip system for simple connection and extension adjustable construction through use of T-pieces, corners, inspection shafts and stacking elements branch channel adapters that connect to the drainage channel with the aid of cut-out sections Description 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. Our innovative branch channel system “Subterra” is here to solve this problem.  The solution to the problem lies in our drainage channels: pre-perforated cut-out sections allow the channel 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.
