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

Bentonit WaterSeal \u2013 BWE 2030<\/strong><\/p>\n

Bentonite waterstop is a highly elastic sealing material based on sodium bentonite<\/strong> in a butyl rubber matrix<\/strong>, specifically designed to prevent water infiltration and leakage in construction joints and concrete cold joints. This waterstop expands upon contact with water, forming a barrier against water penetration through concrete joints. It is installed using adhesive or nails<\/strong> and embedded within the next concrete pour.<\/p>\n

Bentonite waterstops serve as a suitable alternative to PVC waterstops<\/strong> in areas where conventional PVC systems have not been installed. However, they should only be used in construction joints<\/strong> and are not suitable<\/strong> for expansion or contraction joints. One of the key advantages of bentonite waterstops is their ability to be installed on uneven concrete surfaces<\/strong>, making them ideal for sealing potential cold joints<\/strong>.<\/p>\n

Key Features and Benefits<\/strong><\/h3>\n
    \n
  • Provides effective sealing<\/strong> for cold joints, protecting reinforcement bars<\/li>\n
  • Fills voids and cavities within concrete structures<\/li>\n
  • Suitable for use in heavily reinforced concrete sections<\/li>\n
  • Can be applied on uneven concrete surfaces<\/strong><\/li>\n
  • Maintains original shape<\/strong> under high water pressure<\/li>\n
  • Highly resistant to moisture, humidity, and repeated wet-dry cycles<\/strong><\/li>\n
  • Offers delayed swelling<\/strong> for controlled expansion<\/li>\n
  • Delivers permanent, reliable performance<\/strong><\/li>\n
  • No need for overlapping or welding<\/strong> during installation<\/li>\n
  • Highly flexible and adaptable to joint contours<\/li>\n
  • Non-toxic and safe for contact with potable water<\/strong><\/li>\n<\/ul>\n

    Applications<\/strong><\/h3>\n
      \n
    • Waterproofing horizontal and vertical construction joints<\/strong><\/li>\n
    • Sealing irregular surfaces<\/strong> and potential cold joints<\/strong><\/li>\n
    • Waterproofing around pipes and replacing traditional flange seals<\/strong><\/li>\n
    • Sealing various construction joints and concrete pouring sections<\/strong><\/li>\n
    • Waterproofing dams, tunnels, pools, and water channels<\/strong><\/li>\n
    • Water-tightening water treatment plants and sewage facilities<\/strong><\/li>\n
    • Protecting foundations, buried structures, and semi-buried structures<\/strong><\/li>\n
    • Waterproofing shear walls and load-bearing walls<\/strong><\/li>\n<\/ul>\n

      Technical Considerations<\/strong><\/h3>\n
        \n
      • Avoid submerging<\/strong> the bentonite waterstop in water before concrete pouring.<\/li>\n
      • Ensure a minimum 50 mm<\/strong> concrete cover over the waterstop.<\/li>\n
      • The substrate must be dry<\/strong> during installation.<\/li>\n
      • Not suitable<\/strong> for sealing joints in precast concrete elements.<\/li>\n
      • Protect from heavy moisture and direct rain<\/strong> before concrete placement.<\/li>\n
      • Bentonite waterstops may not expand sufficiently<\/strong> in saltwater environments<\/strong>.<\/li>\n
      • Effective for water pressures up to 12 meters depth<\/strong>.<\/li>\n
      • Minimize the time gap<\/strong> between installation and concrete pouring.<\/li>\n
      • If a significant delay occurs between installation and pouring, cover the surface properly<\/strong> to prevent premature expansion.<\/li>\n<\/ul>\n

        Installation Instructions<\/strong><\/h3>\n
          \n
        1. Surface Preparation:<\/strong>\n
            \n
          • Ensure the substrate is dry, clean, and free from dust, oil, and loose materials<\/strong> before installation.<\/li>\n<\/ul>\n<\/li>\n
          • Fixing the Waterstop:<\/strong>\n
              \n
            • Apply special adhesive<\/strong> to secure the bentonite waterstop to the concrete surface.<\/li>\n
            • For vertical or overhead applications<\/strong>, use steel nails<\/strong> for additional fixation.<\/li>\n<\/ul>\n<\/li>\n
            • Joint Placement:<\/strong>\n
                \n
              • Align the edges of the waterstop strips tightly together<\/strong> without overlapping.<\/li>\n
              • Press firmly to ensure a secure bond<\/strong>.<\/li>\n<\/ul>\n<\/li>\n
              • Final Preparations:<\/strong>\n
                  \n
                • Protect the installed waterstop from direct moisture and rain<\/strong> until concrete pouring.<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n

                  Storage & Shelf Life<\/strong><\/h3>\n
                    \n
