A wide range of floor waste designs are available, each suited to different applications and installation methods. When working on projects that require passive fire ratings, it’s important to consider both the compatibility of the chosen plumbing system and the passive fire protection (PFP) product selected.

Minimising Core Holes for Fire Rating
The size of the penetration (core hole) through the flooring structure should be kept to a minimum for effective fire performance. Easy-clean wastes—often supplied with shower trays and featuring bucket and funnel designs—are convenient for squat flooring cavities but typically require larger core holes and have limited passive fire testing.

According to AS 4072.1:2005, an installation scenario without existing test data can only be used if:

1. 1. It is approved by the regulatory authority;
   2. It is permitted under AS 1530.4; or
   3. It is formally assessed by a registered testing authority.

Large core holes for easy-clean wastes often fall outside tested parameters, meaning slabs may need to be reinstated to suit tested systems. Using plumbing systems designed specifically for tested solutions can streamline installation, removing the need for slab reinstatement.

Allproof Trayrite – Tested & Compliant Solution
Allproof’s Trayrite system allows a shower tray waste to be converted into a traditional floor waste gully, offering:

• Fully tested passive fire protection.
• Single-cut core hole installation.
• The ability to fit a drop-in or retrofit fire collar.

Traditional floor waste gullies also reduce maintenance as they are largely self-cleaning, with water pressure from modern plumbing systems helping to clear debris.

Testing to AS 1530.4:2014
When testing PFP products to AS 1530.4:2014, a temperature sensor is placed at the point of highest exposure—typically the centre of the floor waste grate. This is critical as plastic or metallic components can conduct or combust under fire conditions.

Allproof’s advanced intumescent technology activates early, sealing the opening before temperature thresholds are exceeded, delivering full Fire Resistance Level (FRL) results for insulation and integrity that outperform many global competitors.

Proven Compatibility Across Floor Systems
Allproof provides tested floor waste solutions for a wide range of floor types, including:

A Premium, Sustainable Solution
The new 300 mm clear opening Commercial Channel provides a premium, high-capacity drainage solution that balances sustainability, installation efficiency, safety, and cost-effectiveness.

Waste water management in food and beverage production facilities or commercial kitchens presents unique challenges for drainage systems. These environments often require systems capable of handling large volumes of water, cleaning chemicals, and sometimes sudden liquid releases from production equipment.

Drainage System Selection
In production facilities, routine washdowns can release substantial amounts of water and debris. The drainage system must be able to:

• Handle high flow rates during cleaning and sluicing
• Capture contaminants such as food particles, fats, and cleaning agents
• Prevent flooding and mitigate slip hazards

For areas prone to large liquid discharges, a channel with a 100 mm or 200 mm clear opening is recommended. These wider channels provide superior catchment during sudden releases. For steady but lower flow areas—such as chilled storage or food prep workstations—a slot drain with a 20 mm opening may be more suitable.

Channel Depth & Hydraulic Performance
Channel depth directly impacts drainage efficiency. Deeper channels increase catchment capacity and reduce flood risk. Outlets connected to sumps are often more effective hydraulically as they create a waterfall effect that improves flow rate and system performance.

When flow rate is critical, customised sump depths can be fabricated to meet hydraulic design specifications. This ensures surface water is removed quickly and safely from the facility.

Handling Large Debris & Food Particles
Facilities such as butcheries, fish markets, and food production plants often release large food particles during washdown. In these environments, drains with wide grate openings are preferred to allow debris to flow through easily.

Some facilities use trade waste separators to manage fats and solids downstream, which requires a drainage system that allows solids to pass through without frequent blockages. Allproof Industries provides:

• Custom strainer baskets with varying mesh sizes (e.g., 20 mm openings for meat processing applications)
• Removable handles and rods for easy maintenance and quick sump identification

These systems ensure uninterrupted operations while meeting trade waste compliance requirements.

In light of recent high-profile fire incidents in Sydney and Wellington, fire safety in multistorey buildings has once again become a topic of critical importance. Modern building design requires both Active Fire Protection (AFP) and Passive Fire Protection (PFP) systems to work in unison, ensuring that in the event of a fire, occupants have a safe path to evacuate and emergency services can respond effectively.

Passive fire protection, in particular, plays a crucial role in containing fire and smoke, preserving structural integrity, and ultimately saving lives. It is a silent but essential system that must be embedded into a building’s design from the earliest planning stages.

Understanding Fire Compartments and Penetrations
A building is typically divided into fire compartments—zones created through the strategic use of fire-rated walls, floors and ceilings. These barriers are designed to resist the passage of fire and smoke, limiting their spread both vertically and horizontally within the structure.

However, these barriers are often penetrated by essential building services, such as plumbing, ventilation, and electrical conduits. Each penetration represents a potential weakness in the fire containment system and must be protected with compliant passive fire stopping systems.

What is an FRL (Fire Resistance Level)?
The Fire Resistance Level (FRL) is a measure of a building element’s ability to resist fire, specified in terms of structural adequacy, integrity, and insulation. Determined by a fire engineer, an FRL takes into account the intended use of the space, the mobility and number of occupants, the building’s size and proximity to neighbouring structures.

Each service penetration must be fitted with a tested and certified PFP system that maintains the fire compartment’s FRL, ensuring the system will hold up under real fire conditions.

How Passive Fire Protection Works
When exposed to high temperatures, the intumescent material within a passive fire protection device activates. It expands rapidly, forming a char that fills the void left when combustible materials (such as PVC pipes) melt away. This char acts as an insulator, reducing heat transfer and sealing the penetration to prevent fire and smoke from travelling between compartments.

This process plays a crucial role in slowing down the spread of fire, protecting other areas of the building, and buying precious time for evacuation and firefighting efforts.

The passive fire industry has evolved significantly in recent years, shaped by new research, improved testing, and, unfortunately, by learning from real-world tragedies. By prioritising fire containment at the design stage and working with trusted local suppliers, we can reduce harm and damage in future fire events.

Why Specialist Drainage Matters
Drainage systems play a critical role in maintaining hygiene, safety, and accessibility in aged care facilities, hospitals, and educational buildings. These environments serve some of society’s most vulnerable people, making reliable and well-designed drainage essential for preventing safety hazards, maintaining hygiene, and supporting operational efficiency.

Key Design Considerations
Hygiene and Infection Control
Hospitals, aged care homes, and schools require drainage systems that prevent water pooling, which can spread harmful microbes like Legionella. Stainless steel drainage systems are preferred because they:

• Are easy to clean and resistant to bacteria build-up
• Provide long-lasting durability under heavy use
• Reduce risk of odours and contamination

Accessibility for All Users
AS 1428.1:2021 outlines design requirements for accessible building elements. Drainage should support:

• Level-threshold access for mobility-impaired users and wheelchairs
• Curbless shower drainage in aged care and hospital bathrooms
• Linear drains for safe transitions in public entrances and student housing

Slip Resistance and Public Safety
All pedestrian areas, including hospital corridors, playgrounds, and threshold entries, need slip-resistant grates compliant with AS 4586. Selecting anti-slip grates helps prevent accidents, while ensuring they do not create trip hazards or interfere with mobility aids.

Load Ratings and Durability
Drainage systems in kitchens, loading bays, and heavy foot traffic areas must be designed for the correct load class rating under AS 3996. For example:

• Class A – Pedestrian-only areas
• Class C & D – Loading docks and kitchens with trolley traffic
• Class E+ – Vehicle access or heavy-use environments

Fire Protection
Penetrations through floors and walls must maintain their fire rating. Selecting a system tested to National Construction Code requirements ensures fire safety compliance, particularly in multi-storey healthcare or education buildings.

Responding to a Changing Climate
Extreme weather events are no longer rare occurrences in Australia. In 2022, rainfall was recorded at 26% above the national average, triggering widespread flooding across the eastern states. The pattern is reflected globally, with neighbouring New Zealand experiencing two major storm events in the first months of 2023, including Cyclone Gabrielle, which delivered up to 400mm of rain in just a few days.

As the Intergovernmental Panel on Climate Change (IPCC) reports an increase in the frequency and severity of such events, designers and developers must reconsider traditional stormwater strategies. Effective surface water drainage is no longer a luxury—it is essential infrastructure.

In the face of these challenges, large-capacity drainage systems provide a practical and futureproof solution, particularly in urban environments with limited permeability due to hardscaped surfaces.

Futureproofing Developments with High-Capacity Drainage
Urbanisation across Australia has led to the proliferation of impervious surfaces—roads, car parks, and paved commercial zones—that inhibit natural water absorption. Without well-designed drainage systems, surface water can accumulate quickly, increasing the risk of localised flooding and infrastructure damage.

Allproof Industries offers a range of large-capacity drainage systems that are engineered to manage heavy surface runoff effectively. These systems include 200mm and 300mm wide surface water channel drains, ideal for commercial projects such as loading bays, public spaces, and high-density developments. Paired with large-volume pits, the system is capable of both stormwater collection and sediment separation, helping protect municipal infrastructure from blockages and overflow.

Design Standards and Compliance
Allproof’s drainage solutions are designed in accordance with AS 3996, which governs the classification of access covers and grates for load-bearing performance. Grates are tested and certified to support a range of load classes, from Class A pedestrian areas to Class E heavy vehicle zones, ensuring performance suitability across a variety of environments.

The system’s integrated grate lockdowns prevent movement under dynamic wheel loads, a common source of wear and system failure. This also minimises noise and structural damage over time, supporting the long-term durability of the drainage system.

Material Options for Australian Conditions
Material selection plays a vital role in the longevity and functionality of drainage infrastructure. Allproof’s systems are available in a variety of materials tailored to project-specific needs:

• 316 stainless steel for coastal or corrosive environments

Efficient Drainage Strategies for Multi-Level Australian Buildings
In high-density residential developments across Australia, effective roof and balcony drainage is essential to ensure long-term building integrity, occupant safety, and compliance with building codes. Whether designing recessed or cantilevered balconies, a functional and code-compliant drainage system must account for primary outlets, overflow provisions, and fire protection through passive fire systems.

Understanding Drainage Requirements
Each residential balcony is required to have:

• One primary outlet, which connects to a vertical downpipe servicing multiple levels
• One overflow outlet, to alert building management in the event of a blockage
• Fire protection, particularly where penetrations intersect fire-rated slabs or soffits

To ensure efficient drainage, the system must allow multiple balconies and the roof itself to drain through a shared vertical pipe, reducing penetrations and simplifying maintenance.

Traditional Balcony Drainage Configuration
A conventional approach places a roof downpipe through or alongside each balcony slab. The soffit conceals a junction where individual balcony drains are connected to this shared vertical stack.

In this setup:

• Allproof’s uPVC Three-Way Connector Junction (104.100.65.88) connects a 65mm VRTW balcony drain into the shared downpipe
• The penetration is sealed using the Allproof Balcony Downpipe Flange (BDF100) to maintain membrane integrity
• A VRTW65 OFLOW overflow outlet is added to provide visual notification of potential blockage
• The Allproof Soffit Cover provides a discreet underside finish
• As balconies typically form part of a fire compartment, passive fire protection (PFP) is mandatory. Penetrations are treated using Allproof Fire Collars or equivalent compliant PFP systems

This system aligns with Australian NCC requirements for multi-residential drainage, fire compartmentation, and waterproofing continuity.

Simplified Installation: The Allproof Allthrough System
To streamline installation and reduce the number of penetrations, Allproof offers the Allthrough Drainage System, an integrated solution that allows both the roof and balcony to drain through a single penetration per floor.

Key benefits of the Allthrough system:

• One penetration per level for the roof and balcony outlet, minimising detailing complexity
• Independently tested by a NATA-accredited laboratory, confirming its hydraulic performance of up to 5L/s without water splash-back
• Avoids cross-title drainage issues by preventing discharge from an upper balcony or roof onto balconies below

The Allproof Allthrough AT100 O outlet incorporates a membrane clamp ring with a stainless or plastic grate, ensuring long-term performance with both PVC and bituminous waterproofing systems. An overflow outlet is installed separately using the same base and a riser to maintain waterproofing membrane integrity.

As with traditional systems, each penetration requires fire collars to meet Australian passive fire protection standards in multi-level developments.

Designing for Effective Surface Water Management
Managing surface water around Australian homes is a critical component of site planning and residential design. Whether installed across a driveway, at garage entrances, or along garden paths, residential drainage systems play a vital role in protecting property, enhancing usability, and maintaining compliance with local authority regulations.

Also referred to as channel drains, strip drains, slot drains, or trench drains, these systems are largely interchangeable in function, although some manufacturers may use specific terms to denote subtle variations in design or performance.

Why Driveway Drainage Matters
Driveway drainage is essential for redirecting surface water away from vulnerable areas, such as garages, building foundations, and paved paths. In modern developments, sections are often graded to direct water down toward the street, but this can lead to issues where heavy rainfall overwhelms council stormwater systems or in cases where topography channels water toward the home.

In these situations, strategic placement of driveway channel drains can effectively intercept and redirect runoff. Common installation points include:

• Across the garage door entrance
• At the bottom of a sloped driveway
• Along the property boundary line
• Beside paths and building entry points

Channel drains are particularly useful for capturing stormwater before it enters the home or public footpaths, protecting property and complying with council requirements to minimise runoff from impermeable surfaces.

Drainage at the Garage Door
A garage door drain—installed across the width of the garage opening—is a simple but crucial detail in Australian residential design. It allows for level access into the garage while preventing ingress of surface water during storms.

To ensure effective operation, a slight external ramp is recommended, guiding water away from the internal slab. It is also important that the drain body is installed outside the garage floor slab, allowing for full concrete encasement and structural integrity—particularly important when the system is subject to vehicle loads.

Grate Selection: Function, Form, and Flow
Choosing the right grate affects both the performance and aesthetic of a drainage system. Factors such as hydraulic capacity, safety, blockage resistance, and visual appearance should all be considered.

Key considerations include:

Open area: Grates with a higher open surface (e.g., wedge wire) offer superior flow but may be more prone to blockage or unsuitable for areas where small objects could fall through.

Slot drains: Allproof’s 15mm Slot Drain offers a discreet visual solution for flat surfaces such as courtyards or pool surrounds. However, they may not be suitable at the base of steep driveways where flow rates are higher.

Outlet positioning: Vertical outlets generally allow for faster drainage compared to end-of-line horizontal outlets. Including multiple outlets can also enhance flow efficiency.

Load Rating and Installation Best Practices
Driveway drains must meet appropriate load class standards under AS3996. For residential driveways that support heavier vehicles or boats, a minimum Class C rating is recommended.

Where turning movements are expected (e.g., driveways with narrow access or multiple vehicles), dynamic loads can shift grates. In such cases, using a system with grate lockdowns—like those in Allproof’s Polymer Concrete range—will prevent movement, minimise damage to surrounding concrete, and extend system life.

Proper installation requires full concrete encasement, with at least 100mm of cover below and to the sides of the channel. For paved finishes, concrete should be installed up to the required surface depth to preserve structural strength.

Recommended System: Allproof Domestic Channel
Allproof’s Domestic Channel is an ideal solution for most residential driveway applications. Manufactured from 100% recycled polypropylene using solar energy, it provides a sustainable, lightweight, and durable option that is easy to install and maintain.

Grate Material Options
Selecting the right grate material enhances durability and ensures compatibility with environmental and aesthetic requirements:

• Galvanised Steel: Cost-effective with good durability, though subject to weathering over time as the zinc layer breaks down.
• 304/316 Stainless Steel: Highly resistant to corrosion. 316-grade is recommended for coastal or marine environments.
• Cast Iron: Extremely robust. Offers unique aesthetics through its natural oxidised patina but is generally more suited to commercial or high-load residential areas.
• Glass-Filled Nylon / Polypropylene: Non-reactive, colour-stable, and ideal for modern, black-finish architectural designs.

Maintenance for Optimal Performance
Routine maintenance ensures longevity and performance of driveway drainage systems. It is advisable to:

• Clean grates monthly or whenever external surfaces are washed.
• Adjust cleaning schedules during autumn or storm-heavy seasons.
• Remove and clean grates every six months.
• Clear sediment and debris from pits and sumps connected to the stormwater system.

Seasonal maintenance schedules should be tailored to local conditions across Australia’s diverse climate zones, from tropical QLD and NT to cooler VIC and TAS.

Sustainability and Quality Assurance
Allproof is committed to manufacturing processes that align with environmental goals. By using recycled materials, solar-powered production, and maintaining local manufacturing, Allproof supports reduced carbon footprints while ensuring high-performance products for long-term use in Australian homes.

The product lines include the VRTW (a compact, small-diameter base) and the Sureflow (a large-diameter option), both designed to suit varying project requirements and drainage capacities.

New 88° Side Outlet Product Launch
The latest update to the range includes:

• Two new 88° VRTW bases with 65mm and 80mm outlet sizes
• A new 88° Sureflow base with a 100mm outlet

These integrated 88-degree outlet configurations eliminate the need for separate pipe bends to change direction, which can reduce overall installation depth by up to 100mm. This compact design is particularly advantageous in roof cavities, internal gutters, and balconies, where space is often limited.

By integrating the angled outlet directly into the drain body, specifiers and installers benefit from a more compact and streamlined solution. The resulting space savings can enable longer pipe runs within roof cavities, offering greater design freedom in locating downpipes and simplifying coordination with structural elements.

Installation Features and Material Options
Each drain body features solvent weld connections to ensure a secure and watertight fit to pipework. The PVC flange provides an excellent bonding surface for waterproof membranes, and is paired with a clamp ring to protect membrane edges and create a secure interface for the grate assembly.

Grates and clamp rings are available in:

• UV-stabilised ASA plastic
• 316 stainless steel
• Bronze

These options allow specifiers to tailor the drain system to suit the visual and environmental requirements of each project, from cost-sensitive builds to high-spec commercial or coastal developments.
