Hygienic floor drainage

Hygienic drainage design principles

Floor gullies and drainage channels guide wastewater from floors into the drainage pipe, safely for people and without damage to structures.

It is the installation location, for example, a large catering kitchen, which primarily determines which variant of a gulley or channel for the drainage has to be selected. Depending on their type, they can be combined with extensions.

The most important factors in the design include:
  • Wastewater quantity
  • Traffic load and load capacity of the grating Slip resistance
  • Waterproofing/seals
  • Fire protection requirements
  • Hygienic properties
