HydraFlex - Flexible Tanking Membrane

HydraFlex Tanking Slurry – High-Performance Flexible Waterproofing

Advanced Waterproofing with 7 Bar Water Resistance Pressure

HydraFlex Tanking Slurry is a two-component, flexible waterproofing membrane designed to provide permanent protection for concrete and masonry surfaces. Comprising a cementitious powder and a high-concentration liquid polymer, HydraFlex creates a seamless, watertight barrier that effectively resists hydrostatic pressure up to 7 bar. Its high elasticity and crack-bridging properties ensure long-term durability, even in challenging conditions.

Key Benefits:

✔ High Water Resistance – Tested to withstand up to 7 bar water pressure, making it ideal for below-ground waterproofing.
✔ Flexible & Crack-Bridging – Maintains waterproof integrity down to -5°C, even on substrates prone to movement.
✔ Thixotropic Properties – Can be applied to vertical and overhead surfaces without sagging.
✔ Radon Barrier – Acts as a protective layer against radon gas infiltration.
✔ Versatile Use – Perfect for basements, cellars, foundations, lift pits, podium decks, balconies, terraces, and flat roofs.

Technical Information:

• Water Pressure Resistance: Rated up to 7 bar.
• Mixing Ratio: 15kg cementitious powder + 5kg polymer liquid (total 20kg mixture).
• Coverage: Approx. 6m² per 20kg unit at 2mm thickness.
• Application Methods: Trowel, brush, or roller.
• Pot Life: Approx. 40 minutes after mixing.
• Curing Time: 48 hours (protect from direct sunlight and drying winds).
• Storage: Cool, dry conditions; avoid moisture and frost exposure.
• Shelf Life: 6 months (unopened & stored correctly).

Application Guidelines:

1. Surface Preparation: Ensure the surface is clean, dry, and free from contaminants. Remove loose material, grease, and organic growth. Treat cracks and apply Wykamol Universal Mortar for leveling if needed.
2. Mixing: Gradually add the cementitious powder to the liquid polymer, stirring continuously until a smooth, lump-free slurry is formed. If necessary, add up to 0.5L of clean water for consistency.
3. Application:
   • Apply the first coat at 1–1.5mm thickness, ensuring full surface coverage.
   • Allow to cure before applying the second coat to achieve a total 2mm thickness.
4. Curing: Protect the freshly applied surface from direct sunlight and strong winds for at least 48 hours to ensure proper curing.
5. Overcoating: Once fully cured, HydraFlex can be overcoated with Wykamol Renovation Plaster after 48–72 hours.
