CPD Online - Balcony drainage systems in multi-residential design: Challenges, solutions & the impact of NCC 2025

This CPD online course addresses balcony drainage systems in multi-residential buildings, focusing on the design challenges that lead to water ingress and subsequent building defects. The training covers practical solutions for managing drainage in apartment buildings and explains how the updated National Construction Code 2025 affects design and construction requirements for balconies. The course material walks through common failure points in balcony construction and how proper drainage specification prevents costly water damage to underlying structures and internal spaces.

The topic sits squarely in the remedial building space because balcony water ingress remains one of the most persistent defect issues in Class 2 apartment buildings across Australia. Many existing buildings suffer from poorly designed or maintained drainage systems that allow water penetration into structural elements and residential units. Understanding the NCC 2025 changes ensures that remedial work, new construction, and building certifiers are aligned on current compliance expectations. This kind of technical CPD helps consultants, builders, and strata managers tackle a recurring problem that drives significant remedial costs.
