A key update is found within the NCC’s second volume, which reintroduces prescriptive Deemed-to-Satisfy (DTS) Provisions as an alternative path to achieving regulatory requirements.
This revision offers more flexibility for builders and designers when it comes to meeting waterproofing standards. Instead of strictly adhering to AS 3740:2023, they can now opt for DTS provisions outlined in this volume. This move is aimed at fostering innovation while maintaining building quality and safety.
New Materials for Water Resistance
In line with these alternative paths towards adherence, Volume Two also introduces new materials eligible for water resistance applications. The Australian Building Codes Board’s guidelines have given their approval to fibre cement sheeting as a viable substrate that effectively resists moisture penetration.
Fibre cement sheeting is becoming increasingly popular again due to its durability and cost-effectiveness. It delivers excellent performance when used alongside appropriate sealants and finishes, making it ideal, especially in domestic wet areas like bathrooms or laundry rooms where exposure to water is high.
Besides fibre cement substrates, treated concrete surfaces are also recognized by the updated code as being resistant against potential damage from moisture intrusion.
Treated concrete provides an effective barrier against possible water related issues without compromising aesthetics.
This is crucial considering current trends favor minimalist design styles extensively across South Wales housing provisions and beyond.
Remember: The future trends within residential housing construction will be greatly influenced by such shifts within regulatory frameworks like NCC amendments along with revisions from Standards Australia.

In both Volumes One and Two, these new regulations set more stringent standards for exterior surfaces. The objective is to mitigate potential damage caused by moisture intrusion which can lead towards structural deterioration over time.
A significant amendment includes the need for a comprehensive waterproof barrier system, implemented on all external walls above ground level. This system must withstand weather conditions and prevent water ingress into internal spaces.
New Standards for Balconies and Decks
Balconies and decks have been addressed specifically in the updated NCC provisions as well. Once considered semi-external areas, they now fall under full external areas requiring complete waterproofing solutions according to Volume One of NCC 2023.
This change recognizes that balconies and decks are often directly exposed to rainwater or other forms of precipitation making them prone if not properly safeguarded against water damage.
Rooftop Gardens: A Special Case
Rooftop gardens present another area where specific requirements apply due their unique challenges related with drainage systems coupled with load bearing capacity issues.
According to revised code rooftop gardens should include an appropriate waterproof membrane layer beneath soil beds or planters incorporated within their design.
This measure ensures proper drainage while preventing seepage into underlying structures thereby ensuring long-term durability amidst harsh weather conditions.
These modifications align perfectly with trends predicted by industry experts who foresee residential housing construction evolving based on current shifts within regulatory frameworks like NCC.
Drainage Systems: Designing with the Future in Mind
The landscape of residential housing construction is evolving, particularly in relation to drainage systems. The National Construction Code (NCC) and Standards Australia have implemented new regulations that require a fresh approach to design.
Navigating Adjustments in Floor Waste Falls
In line with Volume Two revisions under NCC 2023, there are now specific guidelines concerning floor waste falls.
This change aims to ensure efficient water flow towards drains while preventing potential health hazards or structural damage over time due to pooling or stagnation.
- A minimum continuous fall of a floor plane towards a waste drain must be at least 1:80.
- Maintaining the maximum continuous fall should not exceed a 1:50 ratio for optimal performance.
Linear Drainage Solutions
An innovative solution emerging from this regulatory shift is linear drainage systems offered by some of Australia’s leading manufacturers.
These modernized approaches create narrow channels along floors or walls, allowing water to be efficiently directed away from wet areas like bathrooms or kitchens.
