AliDrain Balcony Drainage Systems

Compliance is a major part of any building project and drainage is no exception. The BS8579:2020 Standard addresses the issue of balcony drainage and outlines a requirement that free draining balconies should be avoided for safety and comfort reasons. Two alternative options for compliant balcony drainage are presented; Piped drainage (also referred to as Positive Drainage) & Edge drainage. The overall aim of these methods is to reduce nuisance, increase safety, and prevent damage to buildings.

Independently tested to BS EN 12056-3:2000 Part 3, our drainage systems exceed required flow rates for long-term building compliance.
