Which Building Types Use HydroMax?

Traditionally, HydroMax siphonic roof drainage systems have been used for larger roof areas.

Technical beneifts are achieved with smaller pipes able to run completely flat if the catchment area for a roof drain provides flows of above 1.5 litres per second (23 Gallons per minute). Some smaller areas can achieve siphonic flow but careful design is required.

Most markets realise commercial savings when the roofs have an area over 2500 m2 (26,000 ft2).
