This one-hour CPD course teaches builders and project managers how to manage waterproofing risks in residential and low rise construction. It explains why waterproofing failures occur and the structural, financial, and compliance consequences that follow. The course identifies high risk areas such as wet areas, balconies, and below grade construction, and outlines the common failure mechanisms in each. It provides a clear overview of NCC 2022 requirements and relevant Australian Standards, with guidance on achieving compliance on site. It also delivers practical strategies for system selection, installation, inspection, and documentation to prevent defects and protect the project and licence.

This CPD provides general guidance on professional responsibilities and documentation practices. It does not constitute legal advice or replace project-specific contractual or statutory obligations.

By the end of this course, participants will be able to explain why waterproofing failures occur and understand their structural, financial, and compliance impacts. They will be able to identify high risk zones and analyse common failure mechanisms across different construction areas. Participants will be able to apply NCC 2022 requirements and relevant Australian Standards to make compliant waterproofing decisions on site. They will also be able to select appropriate systems and oversee correct installation practices. Finally, they will be able to implement effective quality control, inspection, and documentation processes to reduce defects and protect project outcomes.

  • Explain the primary causes of waterproofing failures and their structural, financial, and compliance consequences.
  • Select appropriate waterproofing systems based on application, substrate, and exposure conditions.
  • Identify high risk zones in buildings and assess the specific failure mechanisms associated with each.
  • Evaluate installation quality through effective inspection, hold points, and on site supervision.
  • Interpret NCC 2022 waterproofing requirements and apply relevant Australian Standards in practice.
  • Implement documentation and evidence of suitability processes to support compliance and reduce liability.

This ensures that CPD efforts align with professional regulatory requirements.

PC12, PC39, PC45, PC55, PC56

PC12 (regulatory requirements and building codes): The course strongly focuses on NCC 2022 and relevant Australian Standards (AS 3740, AS/NZS 4858), requiring participants to understand and apply statutory compliance frameworks in waterproofing decisions.
PC39 (materials, structural and construction systems): Content on selecting waterproofing systems, substrate preparation, and detailing directly relates to understanding material performance and appropriate construction systems in different conditions.
PC45 (quality and performance standards): The emphasis on correct installation, detailing, and adherence to standards aligns with ensuring construction meets required performance and durability benchmarks.
PC55 (record keeping and document control): The course highlights documentation, evidence of compliance, and quality control processes (e.g. hold points, inspection records) as critical risk management tools.
PC56 (identification of defects): A key focus is recognising failure mechanisms, high-risk zones, and defect causes, enabling practitioners to identify and mitigate waterproofing defects during and after construction.

What’s Included

This course examines waterproofing as a critical risk area in construction and how failures impact project outcomes over time. It explores where defects most commonly occur and why certain building zones are more vulnerable than others. The content reviews the regulatory framework that governs waterproofing, including how compliance is demonstrated in practice. It also looks at how different materials and systems perform under varying conditions and what influences their effectiveness. Finally, it considers the role of site processes, supervision, and record keeping in preventing defects and managing long term liability.

  • A 1-hour video session covering NCC-aligned strategies and real-world case studies.
  • An interactive quiz to test and reinforce knowledge.
  • An audio summary version via NotebookLM for flexible, on-the-go learning.
  • A downloadable certificate of completion for CPD compliance reporting.
  • Centralised CPD tracking dashboard to support audits and personal recordkeeping.
