Dumbbell Hollow PVC Waterstop for Walls<\/strong><\/h2>\n

Description of Dumbbell Hollow PVC Waterstop<\/strong><\/p>\n

In large-scale concrete structures such as dams, artificial lakes, and tunnels<\/strong>, high static pressures can lead to waterstop detachment or tearing<\/strong> during concrete pouring. Conventional waterstops may not be effective under such conditions, as they risk separating from the structure<\/strong> during the process.<\/p>\n

To address this issue, Dumbbell Hollow PVC Waterstop<\/strong> is specifically designed for expansion and contraction joints exposed to high static pressures<\/strong>. This waterstop features a dual-sided ribbed profile<\/strong> and reinforced dumbbell-shaped edges<\/strong> along its length for secure attachment.<\/p>\n

A continuous hollow chamber<\/strong> runs along the center of the waterstop, allowing it to absorb expansion and contraction stresses<\/strong> within the concrete structure. This design ensures effective waterproofing and structural stability in expansion joints subjected to high static pressures<\/strong>.<\/p>\n

The Dumbbell Hollow PVC Waterstop<\/strong> is manufactured in 24 cm and 30 cm widths<\/strong>, with thicknesses ranging from 3 mm to 5 mm<\/strong>. Due to its high flexibility and tear-resistant edges<\/strong>, it can be securely fastened to reinforcement bars using binding wire<\/strong>. Additionally, it can be ordered with pre-punched holes<\/strong> for easier installation.<\/p>\n

Key Features of Dumbbell Hollow PVC Waterstop<\/strong><\/h3>\n

Higher tensile strength than standard requirements
\nHigh flexibility in both length and width directions
\nExcellent resistance to acids and alkalis
\nLong service life, equal to the structure\u2019s lifespan<\/p>\n

Applications of Dumbbell Hollow PVC Waterstop<\/strong><\/h3>\n

Prevents water leakage through construction and expansion joints
\nSeals concrete structures exposed to water and liquids
\nWaterproofs channels, dams, and concrete pipes
\nIdeal for hydraulic structures, swimming pools, and artificial lakes<\/p>\n

Installation Method for Dumbbell Hollow PVC Waterstop<\/strong><\/h3>\n
    \n
  • Position the waterstop at the predetermined concrete joint<\/strong>, ensuring that half of its width is embedded in the first pour and the other half in the second pour<\/strong>.<\/li>\n
  • Concrete should be poured gradually to prevent the waterstop from shifting.<\/li>\n
  • In hollow waterstops<\/strong>, the central cavity must align precisely with the designated expansion joint.<\/li>\n
  • Waterstop clips<\/strong> should be used for secure attachment.<\/li>\n<\/ul>\n

    Connecting Two Ends of Dumbbell Hollow PVC Waterstop<\/strong><\/h3>\n

    Two methods can be used:<\/p>\n

      \n
    1. Heat Welding:<\/strong> Use a hot iron to melt both ends, then press them together until they fuse into a single unit after cooling.<\/li>\n
    2. Industrial PVC Adhesive:<\/strong> Overlap approximately 30 cm<\/strong> of both ends, apply PVC-compatible industrial adhesive<\/strong>, and press firmly until the bond is fully secured.<\/li>\n<\/ol>\n

      Storage Conditions for Dumbbell Hollow PVC Waterstop<\/strong><\/h3>\n
        \n
      • Store in original packaging<\/strong>, protected from direct sunlight<\/strong>.<\/li>\n
      • Cover with a protective tarp<\/strong> to prevent exposure to oxygen and ozone<\/strong>.<\/li>\n
      • Under proper storage conditions, the waterstop retains its properties for up to 12 months<\/strong>.<\/li>\n<\/ul>\n
