Balcony Waterproofing Under NCC 2025
Balcony falls formed only in the screed now carry real compliance and defect risk under NCC 2025.
What has actually changed, and what hasn’t. Balcony waterproofing under NCC Volume One Section F for Class 2 to 9 buildings: the 1 in 80 fall formed in the structure, the 70 mm step down and the perimeter hob, thresholds, door tracks and balustrade penetrations, and the dimensioned documentation that gets a balcony through certification.
Secure card checkout. Tax invoice emailed.
4 modules, final quiz and certificate.
Introduction and objectives
Why balconies are a leading defect category in Class 2 to 9 buildings, and why their geometry now draws more scrutiny.
Regulatory Framework and NCC Context
Place balcony waterproofing in Section F, separate what is unchanged from NCC 2022 from what is new, and confirm the edition for your project.
Structural Falls and Drainage Logic
Form the 1 in 80 fall in the slab, not the screed, and show outlets, overflow and discharge on the drawings.
Thresholds, Hobs and High-Risk Interfaces
Resolve the 70 mm step down against access, and detail hobs, door tracks and balustrade penetrations where balconies fail.
Documentation, Compliance Pathways and Risk Reduction
Replace generic notes with dimensioned statements, coordinate structure, facade and hydraulics, and audit your standard details.
Key takeaways
Targeted strengthening, not a wholesale reset: the controls that matter on your next balcony.
Final quiz and certificate
Ten questions on falls, thresholds, hobs and documentation. Pass and the certificate goes straight into your dashboard.
Intermediate. For people who already design, document, assess or build balconies on Class 2 to 9 buildings. Covers external balcony waterproofing under NCC Volume One Section F: falls, drainage, thresholds, hobs, interfaces, compliance pathways and documentation. Internal wet areas and membrane product selection are outside its scope.
Written for the people whose drawings and decisions set the levels.
Architects
You lead the design team, and a balcony leak years later comes back to what your drawings showed.
Building designers
Your standard balcony details were drawn for NCC 2022 and may rely on the screed for the fall.
Structural engineers
The fall, the step down and the hob now sit in the slab, so they land on your drawings.
Building surveyors
You assess balcony drawings where the geometry is implied by a note rather than dimensioned.
Licensed builders
You pour the slab and install to the drawings, and inherit the leak when the detail was never buildable.
Where this hour goes on your record.
National Standard of Competency for Architects (NSCA 2021) performance criteria this course aligns with:
Advice in line with building codes, standards and planning rules
Planning principles and statutory planning requirements
Materials, structure and construction carried into detailed design
Quality and performance standards for materials and systems
Documentation that complies with codes, approvals and the contract
| If you are | How it is recorded |
|---|---|
| An architect | 1 formal CPD point. Aligned with NSCA 2021 performance criteria PC12, PC32, PC39, PC45 and PC46. |
| 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. |
| A structural engineer, building surveyor or licensed builder | 1 hour of CPD on balcony waterproofing under NCC Volume One Section F, 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.
