An advanced roof and balcony rainwater drainage system

FreeDeck is an advanced roof and balcony drainage system. It combines line drainage with point drainage by using an open-sided drainage channel to collect and convey rainwater to drainage points with a raised or suspended deck structure.

The system intercepts water from surface run-off, percolation within the deck and from rainwater outlets.

It is suitable for use in all types of terrace and flat roof constructions requiring level access drainage. It also ideally suited for facade and bi fold door drainage.
