The second option Wrap Around Gutter system with the AliDeck Drainage Channel sited between AliDeck Decking Boards, wastewater is directed to the ends of the balcony where it is captured by the AliDeck Drainage Gutters at each end of the balcony surface but is also connected along the front elevation to reduce the number of downpipes required.
