For floor waste drainage installations requiring a reliable seal and precise height alignment, the 100mm Raised Floor Waste with Megaflex Flange provides an adjustable, WaterMark certified drainage path. The system pairs a solid brass waste grate with an ABS plastic base to ensure long-term durability in high-moisture floor systems.
Adjustable drainage connection
The integrated Megaflex flange serves as the primary connection point within the floor build-up, protecting the surrounding substrate from moisture penetration. To accommodate variations in screed depths and finished tile heights, the grate assembly features an installation height adjustability range of 6.00 mm. The solid brass grate threads directly into the ABS base, allowing installers to wind the grate level down to the tiled surface before final sealing.
Numbers that matter
- 66.00 mm to 60.00 mm height adjustability: The vertical adjustment window measured from the flange to the outlet to align the finished grate level with the tiled floor.
- Ø 102.80 mm outer base diameter: The physical footprint of the ABS base, stepping down to a 100mm outlet connection.
- 145.00 mm overall width/length: The total outer dimensions of the square or round flange flange assembly.
- 13.00 mm grate thread depth: The available thread engagement range on the brass grate for securing and leveling the waste.
Format options
This floor waste is available in two distinct configurations to match specified tile layouts and bathroom fixtures:
- Square Waste (Product Code 14351.01): Features a chrome finish with a 110.00 mm internal square width and 145.00 mm overall length.
- Round Waste (Product Code 14303.01): Features a chrome finish with a 110.00 mm internal square flange width and 145.00 mm overall round diameter.
Frequently asked questions
How is this floor waste installed with the Megaflex flange?
Ensure the outlet pipe is clean and correctly positioned before applying silicone around the Megaflex flange. Align the waste unit, secure it with the specified fittings, and test for leaks after curing.
What prevents leaks with this floor waste?
The Megaflex™ flange is designed to create a watertight seal with waterproofing membranes, preventing subsurface leaks. Its compatibility with various substrates and proper sealing during installation ensures long-term integrity.
Is this floor waste compliant with Australian standards?
Yes, this floor waste is WaterMark Certified and complies with AS/NZS 3500. This certification confirms it meets Australian plumbing and drainage standards for safe and effective use.
Can I use this for non-100mm outlet pipes?
No, this floor waste is specifically designed for 100mm outlet sizes only. Using it with a different pipe diameter will compromise the seal and function, leading to leaks.
What projects is this floor waste suitable for?
It is suitable for residential bathrooms and laundries, commercial wet areas like shower blocks, and outdoor zones such as balconies and patios. The solid brass construction and chrome finish resist moisture.

How to apply 100mm (Raised) Floor Waste with Megaflex™ Flange:
- Clean and prepare the outlet pipe and surrounding surface
- Apply a bead of silicone around the pipe and flange area
- Place the Megaflex™ flange securely over the pipe
- Position the floor waste (round or square) and ensure it is level
- Secure with fittings and allow sealant to cure before use
Product limitations
- Not for: Outlet pipe sizes other than 100mm. The design is specific to this diameter.
- High-volume water: May require additional sealing in areas with continuous high-volume water flow beyond standard wet area usage.
Safety and handling
Personal protective equipment
Wear gloves and eye protection when handling the components and applying sealants.
Ventilation
Ensure adequate ventilation when applying silicone sealants during installation.
First aid
- Skin contact: Wash skin thoroughly with soap and water if sealants come into contact.
- Eye contact: Flush eyes immediately with plenty of water for several minutes. Seek medical attention if irritation persists.
Storage and disposal
Store in a cool, dry place between 5°C to 40°C. Keep components protected to avoid damage. Dispose of waste materials in accordance with local regulations.
Substrate guide
This floor waste is designed for reliable installation across common wet area substrates, ensuring effective integration with waterproofing systems.
Ceramic tiles
Surface prep: Ensure the surface is clean, level, and free of debris to allow for a flush fit. Correct tile bed preparation is essential for drainage fall.
Primer: Not required for the waste itself, but ensure any underlying waterproofing membrane is properly prepared and primed according to its manufacturer's specifications.
Concrete
Surface prep: The concrete slab must be sound, clean, and cured. Ensure the area around the pipe outlet is stable for secure fixing and sealant adhesion.
Primer: Not required for the waste itself. Ensure sealants used for stability and waterproofing adhere properly to the concrete surface.
Waterproof membranes
Surface prep: The membrane surface must be clean, dry, and cured as per membrane manufacturer's instructions. Ensure the membrane is correctly installed and extends to the waste flange area.
Primer: Not required for the waste itself. The Megaflex flange is designed for direct compatibility with waterproofing membranes, but always verify membrane manufacturer's specific recommendations for flange detailing.
