Conventional Drainage

Conventional drainage is the most common type of roof drainage for flat roofs. It is governed by clear design regulations. The required number of rainwater outlets is defined by the size of the roof area. A separate fall

pipe is generally connected to each rainwater outlet — so that rainfall can be drained reliably at all times.
