Detailed Information

Product description

DYNAPEX PVC Waterstops are at the forefront of advanced technology and design, meeting international standards
such as ATSM, BS,etc. DYNAPEX PVC Waterstops are extruded from specially Top-grade Polyvinyl Chloride (PVC)
compound, the basic resin is Virgin Polyvinyl Chloride . They are engineered for use in both water-retaining and
water-excluding structures where a positive seal is required for construction, expansion and contraction joints
in concrete. Concrete structures are only as watertight as the waterstops that seal their joints. With a range
of designs for both internal and external applications, when embedded into the concrete, DYNAPEX PVC Waterstops
create a continuous barrier, making them ideal for preventing water penetration. DYNAPEX can customize our PVC
Waterstop to suit your project’s specific requirements and the material property specifications of your project.
We also have available designs for you to choose from and reference. For more information and diagrams, refer to
the product brochure.

Physical Properties

Installation

• 1. Prepare the Joint Area: Ensure the concrete joint area is clean, free of debris, and any
  irregularities. The surface must be smooth for the PVC Waterstop to fit properly.
• 2. Position the PVC Waterstop: Place the waterstop at the center of the joint where sealing is
  required. For centrally placed waterstops, ensure it aligns perfectly with the center of the concrete slab.
• 3. Secure the Waterstop: Use steel bars, clips, or other securements to hold the PVC Waterstop in
  position. Avoid puncturing the waterstop, as this can compromise its sealing ability.
• 4. Concrete Pouring (First Half): Pour the first half of the concrete while ensuring the PVC
  Waterstop remains in place without shifting. Be sure to vibrate the concrete to eliminate air bubbles around
  the waterstop.
• 5. Check for Proper Alignment: Before pouring the second half of the concrete, double-check the
  alignment and position of the PVC Waterstop to ensure it’s securely embedded and properly centered.
• 6. Concrete Pouring (Second Half): Pour the second half of the concrete, again ensuring proper
  compaction around the waterstop to prevent voids or gaps that could lead to leakage.
• 7. Welding or Splicing: For longer sections, PVC Waterstops can be welded on-site using specialized
  tools. Clean the ends, heat them with a welding tool, and press together to form a secure, seamless
  connection.
• 8. Inspection and Testing: After installation, inspect the waterstop placement to ensure there are no
  gaps or misalignments. Conduct any required tests to verify the seal’s integrity.

By following these steps, the PVC Waterstop will create an effective barrier against water leakage, ensuring
long-term performance.
