Installation

  • Construction Preparation

    Clean the base surface to ensure it is dry and level. Inspect the waterstop, verify specifications, and prepare necessary tools.

  • Base Surface Pretreatment

    Dry wet areas, repair surface defects, and mark the bonding position with layout lines.

  • Cutting and Splicing

    Cut the material to the required joint length. Ensure lap joints ≥ 50 mm and press firmly to eliminate gaps.

  • Bonding and Fixing

    Peel off the release film and apply along the marked lines. Roll to remove trapped air, bend slowly at corners, and secure loose sections.

  • Finished Product Protection

    Avoid stepping or impact. Recheck bonding before concrete pouring and repair any warping or detachment.

  • Concrete Pouring Control

    Avoid coarse aggregate impact. Vibrate concrete in layers away from the waterstop and correct any displacement after pouring.
