Ensure your outdoor spaces are protected against moisture penetration with our Pre-Formed, External Waterproofing Panels. Crafted for durability and ease of installation, these systems are less labour-intensive than traditional methods, helping you save time and reduce costs. Our range includes Balcony Floor Panels, Subfloor Systems, Porch Columns, Planter Boxes, Ramps, and Dado Panelling—all engineered with graded falls that meet and exceed Australian drainage standards.

Made from high-density polyurethane, each panel creates a powerful moisture barrier and can be tiled, rendered, painted, or finished with permeable stone to suit your design needs. Custom manufactured to any size, they deliver a flawless, watertight finish every time, ensuring long-term protection against leaks and cracks.

Factory-coated with our Cureflex SLR2000 Waterproof Membrane, these External Waterproofing Panels are built to withstand harsh weather conditions, making them ideal for outdoor environments. Engineered with precision through CAD and CNC machining, our Waterproof Flooring Systems guarantee accurate dimensions and faster project turnaround.

Lightweight and easy to handle, they enable quicker installation with fewer trades, and their fast-curing properties support efficient construction. Proudly CodeMark Certified and 100% impervious to water, our Pre-Formed Panels provide a durable, reliable solution for a range of external waterproofing applications.
