Megaflex PVC Waterproofing Puddle Flange

Megaflex Puddle Flanges are used to create a secure waterproofing termination where drainage pipes penetrate concrete slabs or screeds. The flange provides a bonding surface that allows liquid or sheet waterproofing membranes to seal around the pipe penetration and prevent moisture tracking into the slab. Commonly installed in bathrooms, balconies, podium decks and other wet areas, puddle flanges form a critical interface between the drainage pipe and the waterproofing system. Manufactured from high-grade PVC, the Megaflex flange is WaterMark certified for compliance with Australian plumbing standards and suitable for use in both residential and commercial drainage installations. Available outlet sizes include 50mm, 80mm and 100mm to suit common plumbing pipe penetrations.
