Hydrophilic Swelling Waterstop<\/strong><\/h2>\n

Hydrophilic WaterSeal \u2013 WHL 205<\/strong><\/p>\n

Hydrophilic waterstops are made from unvulcanized thermoplastic elastomer (TPE) and are highly effective for sealing construction joints. These waterstops expand upon contact with water, reaching approximately 400% of their original volume after 14 days. The swelling process begins within 6 hours of water exposure.<\/p>\n

A key point about hydrophilic waterstops is that they should only be used in construction joints and must not<\/strong> be applied in expansion joints. These waterstops are composed of water-absorbing materials, preventing water infiltration into critical structural areas.<\/p>\n

Key Features and Benefits<\/strong><\/h3>\n
    \n
  • Provides waterproofing for concrete structures under water pressure up to 6 bar<\/strong><\/li>\n
  • Reduces installation errors compared to PVC waterstops<\/li>\n
  • Offers reversible swelling in the presence of water<\/li>\n
  • Maintains structural integrity even at high temperatures<\/li>\n
  • Non-toxic and safe for use in potable water reservoirs<\/li>\n
  • Easy installation with minimal risk of error<\/li>\n
  • Cost-effective waterproofing solution<\/li>\n<\/ul>\n

    Applications<\/strong><\/h3>\n
      \n
    • Suitable for construction joints exposed to groundwater, surface water, and humidity<\/li>\n
    • Can be applied in both horizontal and vertical<\/strong> construction joints<\/li>\n<\/ul>\n

      Installation Instructions<\/strong><\/h3>\n
        \n
      1. Surface Preparation:<\/strong> Ensure all surfaces are clean, dry, and free of loose particles<\/strong> before installation.<\/li>\n
      2. Placement:<\/strong> Position the waterstop manually into the designated groove in the concrete.<\/li>\n
      3. Clearance:<\/strong> Maintain at least 8 cm distance<\/strong> from the waterstop edges.<\/li>\n
      4. Fixation:<\/strong> Secure the waterstop using adhesive, nails, or screws<\/strong> at 25 cm intervals<\/strong> to prevent displacement.<\/li>\n
      5. Overlapping Ends:<\/strong> Overlap roll ends by at least 3 cm<\/strong> to ensure a continuous seal.<\/li>\n
      6. Additional Waterproofing:<\/strong> Apply a cementitious crystalline waterproofing layer<\/strong> to the substrate before installing the waterstop.<\/li>\n
      7. Joint Configurations:<\/strong>\n
          \n
        • Corner Joints:<\/strong> Cut the waterstop at a 45\u00b0 angle<\/strong> and overlap the vertical strip over the horizontal strip.<\/li>\n
        • Cross (+) Joints:<\/strong> Cut four sections at 45\u00b0 angles<\/strong>, align them to form a cross, and secure with nails or screws.<\/li>\n
        • T-Joints:<\/strong> Place two waterstop strips perpendicular to each other and fix them securely.<\/li>\n<\/ul>\n<\/li>\n
        • Concrete Pouring:<\/strong> Complete the concrete pour shortly after installation<\/strong> to maintain effectiveness.<\/li>\n<\/ol>\n

          Storage & Shelf Life<\/strong><\/h3>\n
            \n
          • Can be stored for up to 2 years<\/strong> in original packaging under normal environmental conditions.<\/li>\n
          • Protect from direct sunlight and excessive moisture.<\/li>\n<\/ul>\n

            Packaging<\/strong><\/h3>\n
              \n
            • 15-meter rolls<\/strong><\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"
