Waterproofing a pool—particularly a commercial or high-rise one—isn’t just about stopping leaks. It’s about choosing the right system for the environment, ensuring substrate preparation, and achieving long-term performance.
Start with the right primer. ARDEX WPM 300 is ideal for concrete substrates with moisture levels above 5%. It forms a sealed base layer that prevents blistering and promotes adhesion.
Next comes the membrane. WPM 002 is the gold standard for internal and submerged zones. It’s flexible, solvent-free, and compliant with AS4858. Two coats are typically applied, reinforced with STB/STA tape at junctions, penetrations, and corners.
In high-traffic or rooftop applications, these layers are followed by screeding, tile adhesive (ARDEX X77 + E90), and flexible grout (ARDEX FG8 with booster). This full system ensures not only waterproofing but also robust tiling performance.
In Perth’s climate, thermal movement and UV exposure can degrade inferior membranes quickly. Always verify your contractor uses "commercial-grade materials" and adheres to the WA Code of Practice for Aquatic Facilities.
