Frequently asked questions
How is the Megaflex™ Puddle Flange installed in a concrete slab?
Position the flange at the pipe penetration, secure it, and pour concrete around it. Ensure the flange is sealed into the waterproofing membrane for a watertight finish.
Is the Megaflex™ Puddle Flange suitable for waterproofing applications?
Yes, it is specifically designed for waterproofing. The flange creates a durable, high-grade PVC water-stop that prevents moisture tracking at pipe penetrations in concrete slabs.
Can this flange be used with all pipe materials?
It is compatible with PVC and CPVC pipes. For other pipe materials, ensure that correct adaptors or fittings are used to maintain a secure and watertight connection.
Is the Megaflex™ Puddle Flange approved for potable water systems?
No, it is designed for drainage and waterproofing, not potable water. For drinking water applications, use products that are specifically WaterMark-certified for potable water contact.
Applications and benefits
| Application | Key benefit | Primary trades |
|---|---|---|
| Concrete slab penetrations in wet areas | Creates a permanent water-stop, preventing water tracking and slab damage at pipe entries. | Plumbers, Waterproofers, Concreters |
| Basement waterproofing and drainage systems | Ensures watertight integrity where pipes pass through structural elements, reducing risk of water ingress. | Waterproofers, Civil Contractors |
| Commercial and residential wet area plumbing | Provides a reliable, AS/NZS 1260 compliant seal for shower, toilet, and laundry drains in concrete floors. | Plumbers, Builders |
| Integration with waterproofing membranes | Designed to accept and bond with liquid or sheet membranes, forming a continuous barrier around penetrations. | Waterproofers, Tilers |
How to apply Megaflex™ Puddle Flange:
- Determine pipe location and cut hole in formwork
- Place flange around pipe, aligning with slab and membrane
- Secure flange and apply solvent cement to pipe and flange
- Pour concrete around flange, ensuring no movement
- Allow concrete and cement to cure fully before testing
Product limitations
- Not for: Pressurised systems or potable water use. It is engineered for drainage and waterproofing applications only.
- Installation timing: Must be installed prior to the concrete slab pour to ensure proper integration and effective sealing.
- UV exposure: Limited UV resistance. Not suitable for prolonged outdoor exposure without protection.
Safety and handling
Personal protective equipment
Wear gloves and eye protection. Use a dust mask if cutting or abrading the flange material.
Ventilation
Ensure adequate ventilation when applying PVC cement or other solvents during installation.
First aid
- Inhalation: If dust or fumes from cutting are inhaled, move to fresh air.
- Skin contact: Wash thoroughly with soap and water.
- Eye contact: Rinse immediately with plenty of water for at least 15 minutes.
Storage and disposal
Store in a cool, dry place, away from direct sunlight and heat sources. The flange has an indefinite shelf life when stored correctly. Dispose of waste in accordance with local regulations.
Substrate guide
Proper substrate preparation and integration ensure the Megaflex™ Puddle Flange creates a reliable water-stop at penetrations.
Concrete slabs
Surface prep: Ensure the area where the flange is positioned is clean and free of debris. The flange is integrated during the concrete pour itself.
Primer: Not required for the flange's direct integration into concrete.
Waterproof membranes
Surface prep: The membrane surface must be clean, dry, and prepared according to the membrane manufacturer's specifications for sealing around penetrations.
Primer: Follow the waterproofing membrane manufacturer's guidance for primer application to ensure a strong bond between the membrane and the PVC flange.
PVC piping
Surface prep: Pipes must be clean, dry, and free from burrs or grease. Chamfer pipe ends as per standard plumbing practice.
Primer: Use a compatible PVC primer before applying PVC cement to ensure a strong, solvent-welded bond between the pipe and the flange.
