ACO Gravity drainage

  • Cast iron (EN-GJL‑200)
  • Stainless steel (grade 304)
Product description

Flat roof gullies for gravity drainage are used for draining small flat roofs with a surface area of less than 150 m2 per gully. However, this kind of drainage can also be used for larger roofs. Whether the roof covering is a membrane, concrete or gravel, ACO Spin flat roof gullies can be flexibly adapted to suit different requirements. The individual components of the gullies such as gratings, top sections and gully bodies can be combined as needed using our building block system.

ACO Siphonic drainage

Product description

Traffic-free roof areas which are no larger than 150 m2, such as production buildings, hangars or sports stadiums, are suitable applications for siphonic drainage.
When the rainfall is heavy enough, the gullies create reduced pressure in the pipe system. This means that an increased level of drainage performance can be achieved compared to simple gravity drainage.

Siphonic drainage can be used on membrane, concrete and gravel roofs as well as on green roofs with extensive planting. When sizing and installing a siphonic system, there are a series of guidelines to be followed. That is why our own internal Application Technology department will be happy to carry out the calculations relating to the system for your project, including the isometric diagram of the pipe layout and creating a list of the materials required
