Siphonic roof drainage solutions are ideally suited to modern high volume structures. In particular, large footprint buildings such as warehouses, factories, airports and distribution centres are prime candidates for siphonic roof drainage. The ability to transfer the water at high levels to the building boundaries, avoiding roof penetration and internal downpipes, allows for maximum use of both floor and roof space. In addition to these building types, the flexibility and innovative design of siphonic solutions lends itself to 'non-standard' designs such as sports stadia and designs of a radical nature!
