How to achieve compliance with BS8579 when using edge drainage

  • Video demonstration: Water drains between decking board gaps (3-6mm), which is then collected on soffit drainage boards, and flows to through gutter and out via the edge of the gutter.

As the name implies, in the edge drainage scenario water is collected and directed to an edge where it is thrown clear of the building. Balconies and terraces which project no more than 2.5m from the face of the building may be drained over a perimeter edge into open space provided the run-off does not cause damage or staining to surfaces below, or damage or erosion to landscaping, or nuisance to people using or visiting the building.
