FlexiFlange

Stormtech, a leader in innovative drainage solutions, has created the FlexiFlange, a patented flexible leak control flange engineered to revolutionise waterproofing installations. This groundbreaking product is the first of its kind in Australia to meet the Deemed to Satisfy requirements of the National Construction Code (NCC) and Watermark.

FlexiFlange represents a significant leap forward for waterproofing installers, offering a solution that addresses critical challenges in compliant drainage and waterproofing applications.

Key Features and Installer Benefits

• The core innovation of the FlexiFlange is its ability to bend up the wall. This allows for the compliant installation of drainage systems hard against vertical surfaces, such as wall and floor junctions.
• The unique flexibility ensures that the required minimum 50mm membrane adhesion area is maintained, eliminating the need to move the drain away from the wall and ensuring a robust, leak-proof seal.
• Crafted from Vinyl Council certified, Best Environmental Practice PVC, FlexiFlange is a ‘deemed to satisfy’ compliant material under AS 3740, AS 3500.2 & AS 4654.1.
• It is Watermark certified.
• It is tested as per AS 4858 guaranteeing its suitability for waterproofing applications.

Additional key features designed to streamline the installation process include:

• Flexible Riser Body: A compression push-fit design provides easy connection to DN100 pipes.
• Large Diameter Flange: Accommodates variability in substrate contours and penetrations, offering greater versatility on site.
• Dry film gauges of 1 and 2mm: Provides an easy guide for membrane application at correct thickness.
• Low-Profile Design: An ultra-thin profile makes installation easier and more efficient.
• Membrane protection and stress relief: Connection between the riser and flange protects the waterproofing membrane from tearing or stress. Slip joint riser allows for natural building movement.
• Built-in Flood Test Plug: A removable flood test plug and water level gauge are built into the flange, simplifying compliance checks.

FlexiFlange is compatible with a wide range of waterproofing materials, including sheet membranes, PVC, and most liquid membranes (excluding bitumen). The flange also features engraved centre lines to assist installers with precise measurements, further reducing installation time and errors.
