Construction Waterproofing 101: Avoiding Common Mistakes
Waterproofing defects start on the drawing, months before anyone opens a bucket of membrane.
Which code applies, and what your drawings have to show. How to confirm the NCC edition, volume and pathway for each project, the wet area dimensions and extents to draw rather than note, the junctions and thresholds where systems fail, what NCC 2025 changed at the balcony threshold, and the record that shows who decided what.
Secure card checkout. Tax invoice emailed.
4 modules, 2 case studies, final quiz and certificate.
Introduction and objectives
Why a waterproofing defect outlasts your involvement, and why two editions of the code are live at once.
Which Code, Which Volume, Which Project
Settle the edition, the volume and the compliance pathway before you draw, and see why a house and an apartment follow different documents.
Wet Areas: The Numbers You Have to Draw
Draw the shower area, the timber floor rule, falls, step downs, hobs and level thresholds as dimensions, not as a note.
Junctions, Thresholds and the World Outside
Detail junctions, flashings and penetrations, and apply the NCC 2025 step down, fall and hob at a balcony threshold.
The Drawings, the Evidence and the Record
Know what a waterproofing drawing must show, control substitutions, and keep the record that answers the question years later.
A threshold and the wrong volume
A flush balcony threshold that was never detailed, and a house bathroom detail reused on a Class 2 walk up.
Key takeaways
Three questions at setup, dimensions on the drawing, and the record that protects you later.
Final quiz and certificate
Ten project scenarios across the four learning objectives. Pass and the certificate goes straight into your dashboard.
Foundational. For people who document, build or approve wet areas and external waterproofing on houses and apartments. Covers the edition, volume and pathway question, wet area dimensions under the Housing Provisions and AS 3740, junctions and thresholds, the NCC 2025 balcony provisions, evidence of suitability and the coordination record. It does not qualify you to certify or install a membrane.
Written for everyone whose name can end up on a waterproofing claim.
Builders
You build to the drawings and sign off the substitutions that can quietly break compliance.
Project managers
You carry the programme when a certifier asks which provisions the wet areas were designed to.
Building surveyors
You assess wet area and balcony details drawn from the wrong volume or carried over from NCC 2022.
Architects
You coordinate the levels, falls and membrane standard across the structural and hydraulic drawings.
Building designers
You set the extent, the levels and the standard, and a dispute years later reconstructs what your detail showed.
Where this hour goes on your record.
National Standard of Competency for Architects (NSCA 2021) performance criteria this course aligns with:

Performance standards for materials and systems
Record keeping and document control in construction
Defects, rectification and substitutions
| If you are | How it is recorded |
|---|---|
| A building designer | 1 CPD point. Your certificate, the learning outcomes, the module outline and your quiz result are kept in your dashboard, so you can show what you studied if your CPD is audited. |
| An architect | 1 formal CPD point. Aligned with NSCA 2021 performance criteria PC12, PC39, PC45, PC55 and PC56. |
| A builder, project manager or building surveyor | 1 hour of CPD on waterproofing under NCC 2022 and NCC 2025, recorded on your certificate for your registration body or state scheme. |
CPD On Demand is not a registered training organisation and courses are not accredited by any registration body. Each course is aligned with the relevant competency frameworks and gives you the records to evidence it. CPD rules differ by registration body and state, so check with yours if you are unsure.
Pairs well with.
The Waterproofing Time Bomb: Defending High-Risk Balconies and Podiums
The next step outside: NCC 2025 balconies, podiums and concrete roofs in detail.
Non-Conforming Building Products: Specification Risk, Evidence of Suitability, and Documentation Defence for Building Designers
Evidence of suitability and the substitutions that quietly break a specification.
The Breathable Wall: Understanding Condensation Risks in NCC 2025
The other half of keeping water out: vapour, cavities and membranes in the wall.
