The ProfiLine system is designed to be positioned above the roof or balcony membrane and drains water directly from the pavement surface or down a facade via the grate.  During heavy rain when the landscaping is saturated, excess water will percolate into the trench drain and drain to the rainwater outlet.  During light rain, the water run-off from the surface or facade will percolate out of the channel side walls and help irrigate the landscape.

Perforations in the side walls of the channel allow water that has percolated through the pavement or green roof materials, to drain. It then guides this water to the roof or balcony drain.

If the roof or balcony drain cannot be ideally situated, drainage ducts can be used to discretely direct the water to the required location.

The access grate can be used over the rainwater outlet to provide access for maintenance.
