The advantage of a channel system rather than a regular channel drain or gully is that it can lead away water from a large area, and there are built-in fall units in the channel. Our channel systems - Slot drain and Grate drain - are based on channel drains, gullies, water traps and grates and are both for concrete flooring or tiled flooring without waterproofing membrane. The design makes the installation both simple and secure. In addition, you only need to install one channel drain instead of several gullies in the same area. Both can be combined with T and L-shaped angles, which allow the system to be expanded in two different directions, a total of 24 metres at most (12 metres in each direction). The large gully, together with the buffer created by the channels, creates a system that is well-suited for handling large amounts of water.
