Allproof manufactures a range of plumbing, drainage and passive fire protection products using 100% recycled polypropylene (PP) sourced from post-consumer roadside collections. The material supplier notes that “completely closing the loop guarantees consistent supply and integration of recycled local resin across all industry sectors.”

Roadside recycling is collected, sorted and bundled at a Material Recovery Facility (MRF). These polypropylene bundles are then processed into 100% recycled resin, ready for injection moulding. Allproof uses this material to manufacture products such as the Commercial Channel drain range, with the entire process, from kerbside recycling bin to finished product, completed in Auckland, New Zealand.

The recycling facility recently upgraded its hard plastics wash line, allowing it to increase annual processing capacity beyond 1,000 tonnes of recycled polypropylene. This upgrade further supports New Zealand’s circular economy while ensuring a reliable supply of locally sourced recycled resin.

The facility’s wash process consumes significant volumes of water, which is recycled on-site to minimise usage. As with any high-capacity industrial facility, a reliable drainage solution is critical to maintain safety and operational efficiency. The drainage system must efficiently handle spills, remove hazards and provide rapid water removal in the event of equipment malfunction.

Allproof’s 200mm clear-opening Commercial Channel was selected as the ideal drainage solution. Sixty-three metres of channel were installed around the internal perimeter, with an additional 10 metres of Heelproof Cast Iron (HCI) grate installed at the facility entrance. This area experiences forklift traffic moving large bales of unprocessed plastics and transporting bags of clean, chipped material to the next processing stage. The HCI grate is rated to Class D (AS 3996) and has a P5 slip rating (AS 4586), making it suitable for heavy-duty, wet commercial environments.

Elsewhere in the facility, Glass Filled Polypropylene (GFP) grates were selected for areas with only Class A pedestrian traffic. These lightweight grates also have a P5 slip resistance rating, improving safety, a top priority for the facility’s operators, whose corporate values place safety first.

Both the commercial channel and GFP grates are manufactured at Allproof’s bronze Enviromark® certified facility using solar energy and 100% recycled polypropylene supplied by the same facility where these drainage solutions are now installed. This represents a complete closed-loop system, delivering a sustainable, high-performing drainage solution through collaboration between two innovation-driven New Zealand companies.

Toitū is an internationally recognised, science-driven organisation supporting businesses to achieve sustainable outcomes.

Allproof has made significant progress in improving the sustainability of its operations in recent years. Achieving Toitū bronze certification for its main Auckland production facility further strengthens the company’s credibility and commitment to environmental and social responsibility.

The Toitū enviromark® certification process uses a robust Environmental Management System (EMS) to assess and reduce environmental impact while improving operational efficiency. This structured approach helps manage environmental risks and opportunities, supporting more sustainable business practices.

The bronze certification focuses on best practice business processes, ensuring health, safety and environmental requirements are fully addressed, planned, implemented and regularly reviewed. By monitoring these areas through an EMS, Allproof can operate responsibly and continuously improve.

Allproof’s environmental values have driven numerous improvements over recent years. The company runs a waste reduction and on-site recycling program, reusing material waste from its own manufacturing. Additional waste separation ensures any remaining materials are responsibly processed rather than sent to landfill.

Many Allproof products are manufactured using 100% recycled polypropylene sourced from post-consumer streams. Producing long-lasting products from recycled materials significantly extends the life cycle of plastics and reduces waste.

The Auckland facility covered by the Toitū bronze certification also harnesses clean energy generated by 450 rooftop solar panels, preventing 50 tonnes of CO₂ emissions every year.

Other sustainability initiatives include transitioning to an electric and hybrid vehicle fleet, achieving Best Environmental Practice (BEP) certification, using biodegradable pallet wrap, supporting local environmental groups such as Pest Free Kaipātiki, and implementing advanced PPE technology for improved worker safety.

Certification by a respected independent organisation such as Toitū gives specifiers and end-users confidence in Allproof’s strong environmental and sustainability values, ensuring the company continues to deliver responsibly made, premium products.

Achieving precise architectural details is often crucial to the success of a project, particularly when it comes to drainage systems designed to follow unique building profiles and protect occupants from surface water.

For the Horizon Hotel, Allproof collaborated with Warren Mahoney and Moller Architects to deliver a bespoke curved drainage solution, ensuring level entry around the revolving doors at the main entrance. This design challenge required a custom drainage channel to follow the building’s curved envelope while still meeting all relevant building codes and AS/NZS standards.

Allproof’s Cantilever Bracket system was specified, offering stable support for grates while accommodating dynamic pedestrian traffic. The bracket system is mechanically separated from the revolving doors, protecting the drainage grates from potential movement or impact.

To ensure a perfect fit, Allproof worked from detailed radius specifications provided by the design team. A laser-cut template allowed on-site formation of the curved channel, and precision jigs were used to roll individual wedge wire spokes to suit the diminishing radius of the architectural grates. The entire system was hand-fabricated and subjected to a rigorous QA process.

The Cantilever Bracket solution gives designers confidence in performance, having been rigorously tested for slip resistance, load capacity, hydraulic efficiency, durability, and ease of maintenance. Lock-downs prevent movement from foot traffic or unauthorised access, ensuring long-term reliability.

Allproof’s custom curved drainage systems have also featured in high-profile projects such as the PwC Tower at Commercial Bay, Massey University, and Wai Ariki Hot Pools. For any bespoke drainage system, Allproof’s advanced manufacturing capability delivers premium results tailored to project-specific requirements such as radius, load rating, and traffic type.

Outdoor living areas can significantly improve the usability and comfort of a home or development. This includes everything from small balconies in medium- or high-density housing to spacious patios with pools in premium residential projects.

The Value of Outdoor Living in Australia
Australian architects excel at designing outdoor spaces that complement the local lifestyle, maximising natural light, airflow and views while creating spaces for leisure and social activities.

However, protecting both the outdoor space and the building from surface water and external moisture is a critical design consideration. Efficient drainage safeguards occupant safety, prevents property damage, and supports compliance with National Construction Code (NCC) Volume One – Performance Requirements FP1.4 and FP1.7, which address surface water management and dampness control.

Balconies in Medium- and High-Density Developments
Balconies often act as private outdoor spaces in medium- and high-density housing. Allproof offers a range of drainage solutions that meet Australian Standards while maintaining visual appeal in compact spaces:

• Tile Jacks can be installed above the waterproofing layer to create level thresholds.
• Balcony Dome and Overflow Drains provide safe water removal, or an Allthrough System can be selected for downpipe-connected balcony drainage.
• Soffit Covers minimise the visual impact of overflow penetrations on the balcony below.
• Stainless Steel Overflow Grates include integrated cowl covers to prevent accidental activation when neighbours wash balconies or water plants, as water can flow through tile spacings into an open overflow outlet.

Accessible Indoor–Outdoor Flow
Accessibility and step-free transitions are key design goals for many Australian homes, especially in ageing-in-place and adaptable housing projects. Level thresholds provide:

• Smooth transitions between internal and external areas.
• Better accessibility and mobility outcomes (refer AS 1428.1).
• Protection from surface water entry.

For paved or concrete finishes, a threshold drainage channel designed to meet NCC Deemed-to-Satisfy provisions and AS 3996 (Access Covers and Grates) provides an efficient solution.
Allproof’s Level Threshold Systems are available off-the-shelf or custom-made, with options including R11 slip-resistant wedge wire grates (AS 4586) or tile insert grates for a seamless aesthetic.

Surface Water Management
Managing surface water is critical to prevent accidents, property damage, and non-compliance with the NCC. Allproof offers multiple solutions to meet performance and aesthetic needs:

• Slot Drains (galvanised or stainless steel) attach to Allproof’s polymer concrete and domestic channel systems (made from 100% recycled plastic).
• A continuous 15 mm slot enables concrete or pavers to be laid right up to the edge, leaving only a minimal visual break (or hiding the slot entirely between pavers).

Slot drains terminate at a tile insert sump, providing maintenance access and sediment collection. For outdoor showers, kitchens or centralised drainage points, Allproof’s Storm Series and tile insert pits provide reliable performance.

Partnering with Allproof
Engaging Allproof early in the design process ensures drainage solutions are selected to meet NCC requirements, Australian Standards, and aesthetic preferences.
Allproof products are manufactured from durable materials, designed for performance and compliance, and made to integrate seamlessly into outdoor living environments.

The Foundation Parnell is an Auckland-based luxury retirement village featuring 46 apartments across five levels. It represents retirement without compromise—where every detail, from its prime central location to the smooth operation of a kitchen drawer, is focused on quality, refinement, attention to detail, and, above all, comfort.

Design and Accessibility
Architects Peddlethorp approached the design with a focus on quality and aesthetics while ensuring accessibility for ease of movement and comfort for all residents.
Allproof Industries was engaged to manufacture and supply a range of drainage and passive fire protection solutions, including shower channels, a perimeter channel drain for level entry at the building entrances, and fire collars.

Custom Shower Channels
Allproof supplied approximately 100 Vision shower channels with tile insert grates, each custom-made for a wall-to-wall finish of roughly 1600 mm in length.
Throughout the process, Allproof provided on-site support to ensure accurate measurement, supply, and installation to the highest standard, all without disrupting the project’s tight schedule.

The Vision Series includes a specially designed puddle flange installed by the plumber before waterproofing. Once tiles are laid, channels are measured and fabricated to fit precisely, ensuring seamless integration and preventing delays for other trades.

Why Custom Solutions Were Required
Designing tiled showers and wet areas around off-the-shelf channel sizes is challenging:

• Small variations in measurements naturally occur during construction.
• Outlet positions may not be perfectly centred due to other building elements.
• Designers would need to pre-detail the exact finished dimensions at the early stage, including wall linings, membranes, and tiles.

To overcome these issues, Allproof manufactured all 100 shower channels to measure, providing a perfect wall-to-wall solution for each individual shower space.

Discreet and Accessible Design
The Tile Insert grate for the Vision shower channel was chosen for its discreet aesthetic, allowing the floor tiles to blend seamlessly into the drainage solution while maintaining slip resistance.
The channel was installed across the shower entry, preventing surface water from entering the bathroom and removing the need for hobs or level changes—ideal for improved accessibility.

Passive Fire Protection
For safety, a high-performing passive fire system was required, giving residents time to evacuate during an emergency.
Allproof’s Cast-in Fire Collar (CIFC) was chosen, providing a fully tested, high-FRL solution. Manufactured from 100% recycled polypropylene using clean solar energy, the CIFC delivers reliable passive fire performance while supporting sustainability goals.

Perimeter Drain for Main Entrance
For the main building entrance, Allproof’s Perimeter Channel Drain was specified to create a level, accessible entryway while preventing surface water from entering the building.
The system is mechanically separated from the door joinery using a bracket and leg system, allowing moisture to escape through joinery weep holes.

The Wedge Wire grate was selected for its R11 slip rating and durability, thanks to its 316 stainless steel construction, ensuring long-term performance and safety.

When designing a shower, several factors need to be considered. The space must be functional, safe, appropriate for the intended users, and enjoyable to use. However, the most critical aspect is ensuring it is designed to be watertight.

1. Waterproofing — Membrane or Tray
For membrane applications, the entire shower area is dressed with a sheet or liquid-applied waterproofing membrane and terminated at a drainage outlet, in accordance with AS 3740-2010 Clause 3.14.1 Figure 3.8. The membrane acts as the waterproofing element, with tiles installed over the top as a decorative finish and to protect the membrane system.

Allproof Industries manufactures a range of PVC Puddle Flanges compatible with leading waterproofing membranes. These flanges feature a textured surface ideal for membrane adhesion and include a PVC connection to the Drain Waste Vent (DWV) system incorporating a water trap or floor waste gully. Some sheet membranes require a clamped outlet, and for these applications, the Allproof Tilerite provides the ideal solution.

Allproof also manufactures custom-made Ttile-Over Shower Trays from stainless steel. These trays are made to measure the shower enclosure width and feature a threaded outlet welded to the base for DWV connection. Waterproofing membranes from the walls and surrounding bathroom area are dressed onto the tray. A shower tray offers the highest level of moisture management and assurance, making it ideal for upper floors or projects where leaks could impact multiple tenancies and revenue streams (such as apartments and hotels).

2. Level Entry or Hob
A level entry shower provides a seamless transition between the shower area and bathroom, helping to make the bathroom appear more spacious. Additionally, this improves accessibility by removing level changes that may pose a hazard to some occupants.

AS 3740-2010 Clause 3.4 requires a minimum fall of 1:100 for showers with a hob, screen, or step-down, and 1:80 for level entry showers. However, membrane suppliers often recommend greater falls (such as 1:50) to ensure surface water drains freely.

A level entry shower requires consideration of the flooring structure below. Installation typically involves cutting into joists to allow fall from the substrate downwards so the drainage outlet sits below the finished floor level. This may require engineering input, especially for laminated joists. In most cases, the shower area is trimmed out between timber joists to create a set-down with a screeded fall.

In contrast, a hob entry shower avoids structural modifications below the floor, as the fall is contained within the hob rather than cutting into the substrate.

3. Point Drain vs Channel Drain
Floor falls direct water to a drain positioned at the lowest point. A centrally located point drain requires falls from all directions, often resulting in cross-cuts in floor tiles. This is less desirable for large-format tiles. Using an Allproof linear Vision Shower Channel against a wall means the fall slopes in one direction, maintaining clean lines and full tiles on the shower floor.

For true level entry installations, channels should be placed against the wall opposite the entrance to avoid fall direction conflicts with level flooring at the threshold.

4. Recessed Shelves and Wall Niches
Recessed shower niches optimise space by eliminating shelves that protrude into the shower area. The Allproof Stainless-steel Niche is designed to provide durability and waterproofing integrity, addressing vulnerable corners and joints. Fixed to the timber wall structure, the waterproofing membrane is dressed onto the flange before tiles are applied.

Allproof niches can be customised, allowing wall-to-wall recessed shelving tailored to each shower design.

5. Finishes and Grate Selection
Allproof offers a variety of grate designs to complement different bathroom aesthetics while maintaining durability and high performance. Popular options include the Horizon shower channel grate and Elegance Plate, which feature brushed stainless-steel covers that hide the outlet while providing drainage around the edge. The architectural wedge wire grate offers a premium finish for tiled showers.

For a seamless look, the Invisi Drain or Tile Insert channel drain blends with surrounding tiles, leaving only a narrow drainage gap for a discreet yet efficient outlet that remains accessible for maintenance.

Allproof’s grate options are available in a variety of finishes to match other bathroom fixtures. Powder coating is also available in black, white, gunmetal, or any custom colour.

Engage Allproof for Your Next Project
Allproof offers an extensive product range and expertise for designing and constructing waterproof tiled showers. Engaging Allproof early in the design process ensures the desired aesthetic, functionality, and compliance with Australian standards are achieved.

When Jasmax undertook the repurposing of Auckland University’s B201 building, one of the key challenges was coordinating drainage services within the existing structure while delivering a premium architectural finish.

A standout feature of the redevelopment is the two-storey atrium, supported by a steel and timber hybrid structure spanning 35 m. With visible roof elements forming part of the design aesthetic, an innovative approach was required for stormwater management from the 1500 m² roof.

Custom Roof Drainage Solution
The roof was designed to slope towards the east block, with stormwater discharged through only five custom rainwater sumps into 300 mm diameter internal downpipes.

To meet the unique hydraulic and installation demands, Jasmax engaged Allproof Industries. Working through multiple design iterations, Allproof developed a custom bolted flange system to securely handle the high-capacity flow rates required.

Each sump featured:

• Clamping rings for secure membrane termination
• Removable perforated domes for ease of cleaning and maintenance
• Laser-cut flanges ensuring strong, leak-free joints

These custom stainless steel sumps were designed with BIM (Building Information Modelling) integration to avoid clashes with structural and service elements, resulting in a seamless on-site installation.

Overflow & Aesthetic Considerations
External overflow pipes, essential for stormwater safety, initially posed a visual impact and vermin risk due to their 300 mm diameter. Allproof collaborated with Jasmax to create a bespoke overflow cover, meeting hydraulic performance requirements while delivering a secure and architecturally sympathetic solution.

Threshold & Access Solutions
At the atrium entrance and lower podium, accessibility was a key design priority. Allproof’s Perimeter Drain with 316-grade stainless steel wedge wire grate was selected for its:

• Premium architectural appearance
• Heelproof design for pedestrian safety
• R11 slip resistance (AS 4586) for improved safety in wet conditions

To accommodate a window sill projecting beyond the glazing line, Allproof customised the grate with a folded edge detail, ensuring a neat and compliant 12 mm drainage gap.

Heavy-Duty Loading Dock Drainage
The loading dock required a high-capacity, heavy-duty drainage system capable of handling large commercial vehicles and forklift traffic. Jasmax selected Allproof’s 200 mm clear opening Polymer Concrete Channel Drain with a cast iron grate, providing:

• Load Class E performance (AS 3996) with a 200 mm concrete surround
• Dynamic wheel load resistance to prevent damage from vehicle manoeuvres
• Lock-down grates for secure and vibration-resistant operation

Award-Winning Collaboration
The B201 redevelopment demonstrates how Jasmax and Allproof Industries collaborated to deliver integrated, high-performance drainage solutions from roof to threshold. The project showcases the value of engaging local expertise to achieve architectural intent, hydraulic performance, and durability while meeting strict compliance standards.

In passive fire construction, there are instances where a tested fire stopping system can be applied to on-site variations through the test standard AS 1530.4 – Section 10.12 Permissible Variations.

This section is commonly used to apply fire stopping test results to separating elements and metal pipe penetrations, within the limitations of the standard.

By using permissible variations, Allproof tested solutions on lightweight wall systems can also be applied to concrete or masonry walls. This means Allproof’s lightweight wall test results can be referenced when selecting systems for concrete and masonry walls, as outlined in Allproof’s technical manuals.
The limitation here is that the lightweight wall thickness must be equal to or greater than the thickness of the concrete or masonry wall for the achieved Fire Resistance Level (FRL) to apply. Importantly, the reverse does not apply (you cannot assume concrete/masonry results apply to lightweight walls).

Example: Expanding Available Solutions
For example, if you require test results for a concrete wall with a minimum thickness of 150 mm, Allproof offers 10 tested solutions covering a range of pipe types and sizes.
Using AS 1530.4 permissible variations, Allproof can also offer their lightweight wall testing with a minimum total wall thickness of 90 mm.
This adds over 130 additional solutions that can be used if the achieved FRL meets the project’s requirements.

With new construction methods, materials, and products continually entering the market, the scope of available passive fire protection solutions is rapidly evolving. Educating the industry on permissible variations allows tested solutions from one scenario to be applied in others, greatly increasing the available design options while meeting compliance requirements.

Key Considerations
It is always recommended to:

• Communicate with the Project Team and Fire Engineer when proposing the use of AS 1530.4 permissible variations.
• Ensure fire-rated zones are appropriately considered before adopting any variation.
• Contact Allproof for further details and advice, as additional solutions may be available through alternate test results or alternative solutions.

Examples of Permissible Variations (AS 1530.4 Section 10.12)
Section 10.12.2 – Separating Elements

• Test results for lightweight partitions may be applied to concrete or masonry walls, provided the concrete/masonry wall thickness is equal to or greater than the total lightweight wall thickness.
• Example: A lightweight wall consisting of 13 mm plasterboard on both sides of a 64 mm steel stud equals a 90 mm total wall thickness. These test results can be applied to a concrete or masonry wall of 90 mm or greater and achieve the same FRL stated in the report.
• Note: The reverse does not apply.

Section 10.12.3 – Metal Pipes

• Test results for steel pipes may be applied to copper and ferrous metal pipes, as detailed in Table 10.12.3.1 of the standard, provided the fire stopping system and separating element are identical to the tested system.

Section 10.12.5 – Plastic Pipes

• Test results for plastic pipes cannot be applied to pipes of different diameters, wall thicknesses, or material types.
• Results for vertical penetrations cannot be assumed for horizontal elements, and vice versa.
• Penetrations that are not perpendicular are acceptable only if the fire stopping system has similar exposure and dimensions to the tested prototype.

A leading snack food brand, known for over 150 years of quality food manufacturing, has built a strong reputation as a market leader. Their iconic potato chips remain a cornerstone product, with an extensive range stocked on supermarket shelves nationwide.

To meet increasing consumer demand, the company recently expanded its production facility to increase capacity and efficiency. Designed by Designgroup Architects h+k and completed in 2020, the site processes an average of 400 tonnes of potatoes each week, producing approximately 720,000 packets of chips weekly.

Designing for High-Volume Food Production
The facility features industry-leading automated processing equipment, operating along defined production lines. Each stage of processing—separating, washing, cooking—required dedicated infrastructure to cater to operational demands.

One of the primary challenges was managing high volumes of water and liquid waste, particularly during:

• Daily operations
• Weekly boil-outs and deep cleans
• Emergency water dumps for hazard management

Additionally, the site’s wastewater recycling system required integrated drainage solutions capable of supporting multiple interconnected facilities without compromising hygiene or safety.

Partnering with Allproof Industries
Allproof Industries, specialists in food and beverage production facility drainage, collaborated with the design team to develop and manufacture a customised stainless steel drainage system.

Key priorities included:

• Robust and durable construction for lifetime performance
• Hygienic design to support food safety and cleaning protocols
• Optimised hydraulic performance for high-flow scenarios

Because drainage is embedded within the floor slab, design accuracy and product performance were critical—retrofit or remediation work can be costly and disruptive.

Drainage Design & Components
Load-Class C Ladder Grates (AS 3996)
Heavy-duty ladder grates were chosen due to frequent heavy machinery traffic. Their large open area improves hydraulic performance and allows solids (e.g., potato debris) to be swept into strainer baskets, reducing slip and trip hazards.

Hydraulic Considerations
Drainage channels were designed with sufficient depth and capacity to capture peak wastewater flows and prevent surface flooding. Each channel section terminates at a sump, where hydraulic efficiency benefits from a water head that increases flow rate and speeds wastewater removal. Sump depths were engineered to suit project-specific hydraulic requirements.

Hygienic Stainless Steel Construction
Stainless steel is the preferred material for food processing facilities due to its:

• Non-porous, sealed surface (bacteria and odour resistant)
• Mechanical strength (resistant to dents and damage)
• Ease of cleaning and maintenance

Project Outcome
Allproof supplied and installed 69 m of stainless-steel channel drain and 22 sumps, either connected to or standalone, forming a highly efficient and hygienic drainage network.

By engaging local expertise and Australian manufacturing, the client ensured compliance with food industry hygiene standards while meeting their operational and sustainability goals. The result is a future-ready facility positioned to support ongoing growth in their iconic product range.

A puddle flange, sometimes called a leak control flange, is an essential construction product that ensures a secure connection between waterproofing membranes and drainage systems (DWV – Drain Waste Vent). Required by Australian Standard AS 3740-2010, puddle flanges are vital in preventing water leaks and protecting surrounding structures from moisture damage.

There are two main variations: those designed for tiled floors and those intended for vinyl floors. Each performs the same fundamental role but is adapted to interact with the different flooring systems.

Tiled Floor Puddle Flanges
A tiled floor puddle flange is generally manufactured from PVC and is approximately the size of a dinner plate, providing a generous bonding area for waterproof membranes. Installed within a rebated section of the floor substrate, it creates a sealed, “tanked” area that directs water toward the central outlet, which connects directly to the plumbing system. Once tiling is complete, an adjustable spigot allows the grate to sit perfectly flush with the finished surface

Modern designs have improved installation efficiency. For example, Allproof’s Cyclone and Tilt-a-Grate flanges feature adjustable spigots for easy alignment, while the Revolver system incorporates a removable gully bucket, ideal for areas where cavity depth is restricted.

To complement the flange, a wide variety of grates are available. Stainless steel designs, such as Allproof’s Elegance, Wakatipu and Kaiteri series, combine durability with refined aesthetics, including lid-style grates that conceal waste outlets for a discreet and sophisticated finish.

Linear Shower Channels
Linear shower drains are increasingly popular in modern bathrooms, offering clean lines and efficient water management. Installed against a wall or at the threshold, they require a single-direction floor fall, reducing tile cuts and installation time.

Allproof’s Vision Series uses a rectangular puddle flange for dual-barrier protection against surface and subsurface water, while the SC Series incorporates the flange directly into the stainless steel channel for a fully tanked, integrated solution. Both systems support removable grates, including tile insert options that create a seamless appearance.

Vinyl Floor Puddle Flanges
Vinyl flooring integrates waterproofing and the finished surface into one continuous layer. The puddle flange is rebated into the substrate, with the vinyl membrane dressed into the flange and secured by a clamping ring to create a watertight seal. A cam-lock grate completes the installation.

While PVC flanges are commonly used, commercial settings often specify cast bronze for added durability and longevity. Grate finishes include chrome on brass, polished brass and stainless steel, allowing for both robust performance and an aesthetic match to the surrounding environment.

The Importance of Puddle Flanges
Whether for tiled or vinyl floors, puddle flanges are fundamental to maintaining building integrity by preventing leaks and meeting mandatory compliance standards. High-quality designs, such as those produced by Allproof, ensure long-term reliability, straightforward maintenance and compatibility with a variety of grate and channel systems.
