Square Bermuda Lowline Megaflex™ Floor Waste – 100x100mm is a professional-grade drainage solution engineered for internal tiled wet areas where minimal screed depth is critical. This solid brass unit incorporates an ABS Megaflex™ base that provides a ±10mm lateral tolerance, allowing installers to compensate for misaligned pipe risers without stressing hydraulic connections or re-coring slabs.
To maintain watertight integrity and prevent delamination, the low-profile flange supports consistent membrane adhesion and penetration sealing, while the solvent-weld compatible base ensures a permanent chemical bond to the drainage system.
Frequently asked questions
Can I install this floor waste in a screeded floor?
Yes, the Megaflex™ ABS base is designed for direct installation into screeded floors and slab systems. It allows for minor adjustment to accommodate pipe misalignment, which is crucial for achieving a flush finish in limited depth scenarios.
Is the Megaflex™ base compatible with solvent cement?
Yes, the Megaflex™ base is made from ABS plastic, ensuring compatibility with solvent-weld connections. Use an approved ABS solvent cement when bonding to ABS pipework, avoiding twisting the base during installation to maintain internal seals.
What outlet size should I select?
The Square Bermuda Lowline offers 50mm, 80mm, and 100mm outlet sizes to suit varying flow requirements. For residential bathrooms, 50mm or 80mm is typically sufficient. High-flow commercial or disabled-access wet areas often benefit from the increased capacity of the 100mm outlet.
Is the Polished Brass (Raw) finish suitable for all projects?
The Polished Brass (Raw) is a living finish that will naturally oxidise and patina over time. It is ideal for projects seeking an evolving, high-end aesthetic. It is not recommended for clients expecting a permanent high-gloss, static look.

Applying Square Bermuda Lowline Megaflex™ Floor Waste – Enhanced Protocols & Best Practices
-
Prepare Floor Substrate
Ensure the floor substrate is structurally sound, clean, and dry. Confirm fall is formed correctly toward the waste location before applying membranes or adhesives.
Concrete Slab
Grind surface clean of laitance. Confirm no pooling occurs at the intended floor waste location.
Timber Subfloor with Screed
Use compressed fibre cement sheeting and form screed to required fall. Waterproof as per AS 3740.
Timing: Allow screed or slab to fully cure (min. 24–48 hours) before fitting Megaflex™ base.Pro Tip: Mark exact centre of pipe riser to pre-align base position before pouring screed. -
Install Megaflex™ Base
Fit the Megaflex™ base to the pipework using approved ABS solvent cement. Press base firmly into position while aligning vertical tolerance.
Solvent Cement Method
Apply ABS-grade solvent evenly to both the pipe and base socket. Insert and hold for 10 seconds to set.
Dry Fit (Inspection Stage Only)
Temporarily place base for height check, then remove and re-apply solvent cement for final fix.
Timing: Cure time for ABS solvent cement: 30 minutes minimum before further works.Pro Tip: Do not overtighten or twist the Megaflex™ body; use vertical pressure only. -
Apply Waterproofing Membrane
Install membrane in compliance with AS 3740. Ensure full coverage around the waste and integrate membrane into the flange where applicable.
Liquid Membrane
Brush membrane into the Megaflex™ base rim, allowing overlap onto the floor for continuity.
Sheet Membrane
Embed fabric around waste with adhesive primer, ensuring tight bond with flange edge.
Timing: Allow full cure of waterproofing before tiling – typically 24–48 hours depending on product used.Pro Tip: Inspect membrane adhesion around the base before tiling to prevent leak paths. -
Fit Brass Grate and Final Finishing
Once tiling is completed and grouted, insert the brass floor waste grate into the Megaflex™ base. Ensure alignment with tiles and test drainage flow.
Push-Fit Grate Method
Align the square grate to tile lines and press downward until seated flush.
Silicone Locking (Optional)
Apply a small bead of neutral cure silicone around the inner lip if required for secure fit in high-traffic zones.
Timing: Allow grout to cure 24 hours minimum before wet testing the installation.Pro Tip: Clean brass finishes using soft cloth and pH-neutral cleaner prior to handover.
Product limitations
- Not for: Vinyl flooring installations due to grate thickness. Use low-profile vinyl floor-specific wastes instead.
- Caution: The Raw Polished Brass finish will patina naturally over time. It is not intended for a permanent high-gloss look.
- Do not use: Acidic cleaners or abrasives on any plated finishes, as this can cause permanent damage.
- Compatibility: The Megaflex™ base is only compatible with solvent weld ABS piping. It is not suitable for push-fit or PVC pressure pipe systems.
Safety and handling
Personal protective equipment
Wear cut-resistant gloves when handling brass components. Use eye protection if cutting screed or tile during fitting.
Ventilation
When using ABS solvent cement, ensure adequate ventilation. Use in open areas or provide exhaust extraction in confined spaces.
First aid
- Eyes: Flush immediately with clean water for at least 15 minutes. Seek medical attention.
- Skin: Wash thoroughly with soap and water. Remove contaminated clothing.
- Inhaled: Move to fresh air. If symptoms persist, consult a physician.
- Swallowed: Do NOT induce vomiting. Rinse mouth and seek urgent medical assistance.
Storage and disposal
ABS cement is flammable; keep away from ignition sources. Store in a cool, dry place away from direct sunlight, flame, or spark-producing tools.
Substrate guide
Proper preparation of the substrate and pipework ensures the waste performs as intended and avoids future failures.
Tile bed / screed
Surface prep: Ensure screed is fully cured and stable. Clean surfaces to remove laitance, dust, and debris. The drain flange must sit flush, requiring a flat surface.
Primer: Not required. For cementitious screeds in good condition, direct embedment is acceptable. Apply waterproofing as per system requirements before tiling.
PVC or ABS drainage systems
Surface prep: Cut and clean pipework for a square, true fit. Use a plastic primer or cleaner to remove manufacturing oils and ensure a secure solvent-weld bond.
Primer: Required. Use an approved PVC/ABS primer prior to solvent welding. Allow full cure time before backfilling or applying mechanical loads.
Waterproof membrane interface
Surface prep: Waterproof membranes must be fully cured and free from contaminants. Ensure the waste flange integrates securely into the membrane system, without pinholing or bridging.
Primer: Optional. For improved bonding with liquid membranes, prime the brass flange with a manufacturer-approved primer before membrane application.
Timber subfloors (with tile underlay)
Surface prep: Timber must be structurally sound and reinforced with fibre-cement underlay. Fasten securely to prevent movement and seal joints with approved tapes or waterproofing compounds.
Primer: Required. Use a moisture barrier primer on timber substrates before waterproofing membrane or flange installation.
