Product Overview

Positive drainage is a common topic during balcony design. Primarily because there are standards and influential organisation in the residential sector (for example the NHBC) which give guidance regarding rainwater management.

The NHBC “Pitched Roof ” guidance is generally considered as best practice. Section 7.2.22 states “drainage should be provided where roofs are greater than 6m², however consideration should be given to providing drainage to smaller roofs, such as dormer, porch roofs or balconies.”
