Akasison Siphonic Drainage

Akasison siphonic roof drainage is a concealed system that rapidly drains water from commercial roofs.

  • Ideal for large footprint premises with minimal roof fall such as warehouses and factories.
  • Freedom of Design: The system allows for flexible routing of pipework.
  • Space Saving: Smaller pipework can be installed horizontally with zero gradient, creating more usable space.
  • Cost Efficient: Fewer pipes and minimal groundwork means reduced costs.
