In Australia, channel drainage systems must comply with requirements set out in the National Construction Code (NCC) and relevant Australian Standards to ensure safety, accessibility, and effective drainage.

Key considerations include:

Dimensions and gradients:
While the NCC does not specify exact minimum widths or depths for channel drains, designers should ensure sufficient size to handle expected water flow. A minimum fall of 1:200 along the length of the channel toward the drainage outlet is recommended for effective drainage.

Grating requirements:
According to AS 1428.1 – Design for Access and Mobility, grates must:

Be independently supported and not rely on door frames or adjacent structures.

Be removable for maintenance and cleaning access.

Have load ratings in accordance with AS 3996, suitable for the expected traffic (pedestrian, light vehicles, or heavy vehicles).

Feature gap sizes that prevent wheels of wheelchairs, mobility aids, or walking sticks from becoming trapped, typically with openings no larger than 8 mm.

Maintain a continuous gap of at least 12 mm between the grate and adjacent door frame or wall cladding to allow for expansion and prevent trip hazards.

Level thresholds and accessibility:
Channel drainage installed at level thresholds must not compromise access requirements under the Disability Discrimination Act and should provide a smooth, slip-resistant surface that meets AS 4586 slip resistance standards.

Because of these combined requirements, a simple three-sided channel without a fall or proper grating design will typically not satisfy the NCC or Australian Standards for safe and accessible drainage solutions. Selecting a drainage system specifically designed for level thresholds and compliance with all relevant standards will help avoid costly alternative solution processes and ensure regulatory approval.

Yes, providing fall in your drainage channel is generally required to ensure effective drainage.

Here’s why and what the standards say for Australia:

The National Construction Code (NCC) and Australian Standards recommend that drainage channels have a minimum fall (slope) of around 1:200 (i.e., 1mm drop per 200mm length) along their length to allow water to flow freely towards the outlet and prevent pooling or blockages.
Without adequate fall, water can stagnate, leading to overflow, leaks, or water damage.
However, in some specific level threshold applications (like flush entrances for accessibility), specially designed drainage systems may accommodate very minimal or zero fall by using engineered grates and outlets that still provide adequate water capture and flow.
It’s important to consult with your drainage supplier or engineer to choose a system designed for your project’s needs and to comply with AS 1428.1 (Design for Access and Mobility) and AS 3996 (Load rating of covers and grates).
Unless your drainage system is specifically designed and tested for a level (no fall) application, you should provide the recommended fall to ensure proper drainage performance and compliance with Australian building regulations.

Allproof can accommodate any variations in your level threshold channel width with our in-house design, development, and fabrication teams.

Our team will visit your site, discuss the available options, and determine the best solution for your project. We will then measure and design custom width frames tailored to your specific needs, ensuring a perfect finish for your project.

Allproof supplies a range of level threshold products designed for various installation scenarios. Engaging our services early in your project ensures we can help you find the best solution.

Our Level Threshold brochure outlines our product offerings and provides guidance on the factors to consider when selecting your system and installation methods for each product.

Great question! The 150mm (depth) x 200mm (width) channel dimensions for a level threshold come from Australian accessibility and building standards, mainly to ensure:

Adequate capacity
The channel must be large enough to collect and drain surface water efficiently, especially since there’s little to no fall to help gravity assist flow. A larger cross-sectional area helps handle sudden water loads from rain or cleaning.
Wheelchair and mobility aid safety
The dimensions ensure the channel and grate can accommodate wheels without trapping or causing hazards — this is important for compliance with AS 1428.1 (Design for Access and Mobility), which governs accessible design.
Structural stability
A substantial channel size ensures the grate and surrounding structure are robust enough to withstand loads without deflecting or failing, important for pedestrian safety and durability.
Compliance with NCC and Standards
The National Construction Code (NCC) references minimum channel sizes to maintain consistent and safe drainage at accessible entries and level thresholds.
In essence, the 150mm x 200mm size balances functional drainage capacity, safety for users (including those with mobility aids), and structural integrity — all while meeting regulatory requirements.

Allproof has extensive experience in this area and offers a comprehensive range of solutions. We are always available to advise on product selection and assist with any questions, from initial building concept design to on-site troubleshooting, maintaining a strong reputation for service quality.

A level threshold channel itself doesn’t always require waterproofing by code, but it’s best practice to waterproof the surrounding slab upstand and ensure the membrane overlaps the channel. This helps keep the area dry and prevents moisture issues, especially in wet areas or where the slab is insulated. Proper waterproofing around the channel protects the structure and extends the lifespan of the installation.

No, surface water must be directed through a sump, whereas stormwater can be connected directly to the drainage system. To accommodate the downpipe, it can be routed through the perimeter drain system by incorporating a socket into the channel for connection. However, it’s important to note that this arrangement may reduce the channel’s capacity. Therefore, it’s advisable to install outlets on both sides of the penetration to ensure compliance with regulations.

Each of our leak control flange products may have slight variations, but they all serve the fundamental purpose of connecting to a pipe and providing a sturdy surface for waterproofing application. Installation details specific to each product can be found on the respective product pages, and we recommend consulting these guidelines before beginning the installation process.

As a general rule, the flange should be recessed into the substrate, securely fixed in place, and offer ample surface area for the membrane to adhere to. It’s essential to ensure that there is a surface fall towards the outlet to facilitate efficient drainage of all surface water.

Installation methods for Allproof shower channels and wastes may vary between products. However, it is essential that the floor is formed with a consistent slope toward the channel. This ensures effective drainage by directing surface and sub-surface moisture to the outlet.

The required slope can be created using screed or levelling compound. It is recommended to waterproof the area in accordance with the waterproofing supplier’s guidelines, ensuring a secure seal to the Allproof flange. This results in a fully sealed, “tanked” area that enhances waterproofing and prevents moisture ingress.

For detailed installation instructions, please contact Allproof.

For applications that deviate from standard specifications, it is advisable to consult a hydraulics engineer to ensure optimal system performance. As a general guideline, one outlet should be provided for each shower head, and multiple outlets are recommended for channels exceeding 1500mm in length.

Opting for a tile-over shower tray offers a premium waterproofing solution, especially suited to high-moisture environments such as showers. This approach significantly reduces the risk of membrane failure by protecting the waterproofing barrier from damage during construction and throughout the building’s lifecycle, including settling and expansion. Implementing such preventive measures can help avoid costly repairs associated with membrane failure, thereby ensuring enhanced longevity and durability for the construction project.
