Waterstop Perforated Sole – High-Reliability Joint Sealing for Concrete Structures

The Waterstop Perforated Sole is a high-performance, heavy-duty sealing solution engineered specifically for horizontal construction joints in concrete slabs where water ingress poses a significant risk. This waterstop variant features a hollow body with deeply grooved, raised treads, providing exceptional mechanical anchorage to the concrete and preventing slippage or displacement during pouring and compaction.

Its perforated, treaded design is a key innovation: the small grooves and high-profile ridges allow the waterstop to interlock mechanically with the surrounding concrete, increasing bonding and reducing the risk of water bypassing through the joint line. The high thickness and rigidity of the product ensure that it maintains its shape and position even under intense pressure and vibration during concreting.

Properties and Effects

• Exceptional Dimensional Stability: With an extra-thick profile and reinforced tread pattern, this waterstop resists deformation or bending during concrete placement, ensuring accurate alignment and joint sealing.
• Superior Flexibility in All Directions: Offers excellent adaptability in both longitudinal and transverse directions, enabling smooth installation across curved or irregular joint geometries.
• Long-Term Durability: The performance lifespan of the perforated sole waterstop is equivalent to the life of the structure itself, thanks to its UV-stabilized and chemical-resistant PVC compound.
• High Chemical Resistance: Capable of withstanding prolonged exposure to acids, alkalis, chlorides, and other corrosive agents typically found in treated water, wastewater, and industrial environments.
• Enhanced Water Sealing Performance: The micro-grooves and deep tread patterns act as capillary barriers, making it nearly impossible for water to migrate through the concrete joint under hydrostatic pressure.
• Heat and Cold Tolerant: Maintains flexibility and sealing performance in extreme temperature conditions, making it suitable for both tropical and cold climates.

Applications

This type of waterstop is ideal for use in hydraulic, industrial, and architectural concrete structures, especially in horizontal and expansion joints. Its superior sealing capability and structural integrity make it essential for projects where water containment and structural longevity are critical. Applications include:

• Sealing Expansion and Construction Joints: Prevents water migration at critical interfaces between concrete slabs and poured walls.
• Dams, Spillways, and Irrigation Canals: Withstands heavy hydrostatic pressure and movement in large hydraulic infrastructure.
• Concrete Pipes and Precast Sections: Provides sealing at the joint lines in large-diameter concrete piping systems.
• Artificial Lakes, Reservoirs, and Reflecting Pools: Maintains waterproofing over extended surfaces and curved perimeters in landscape and recreational structures.
• Underground Structures and Foundations: Prevents groundwater penetration into basements, tunnels, and retaining walls.
• Sewage and Wastewater Treatment Plants: Resistant to chemical attack, ensuring long-term sealing in harsh waste-handling environments.

Advantages Over Conventional Waterstops

• Increased Mechanical Bonding: Unlike flat or smooth waterstops, the perforated sole variant offers more aggressive anchorage into the concrete, reducing displacement during concrete flow.
• Reduced Risk of Water Channeling: The geometry of this waterstop disperses hydraulic pressure and blocks water pathways more efficiently than standard types.
• No Need for Additional Fixing Devices: Its high rigidity and structured profile allow for secure placement without clips or brackets in most use cases.
• Easy Integration with Steel Reinforcement: Can be placed around or through rebars without loss of sealing efficiency.

Installation Tips

• Center the Waterstop in the Joint: For best results, position the waterstop precisely at the midpoint of the joint width during formwork preparation.
• Secure Before Pouring: Use temporary ties or spacers if needed to keep the waterstop firmly in place until the concrete is partially set.
• Overlap with Heat Welding or Solvent Welding: For continuous joint sealing, ensure all splices and corners are joined using approved thermal welding or PVC-compatible adhesives.

Installation Guidelines

For optimal sealing performance, follow these best practices during the installation of Waterstop Perforated Sole:

1. Placement Accuracy: Ensure the waterstop is perfectly centered along the joint, extending equally into both sides of the concrete pour.
2. Fixing Options: Use temporary ties, binding wire, or integrated clips to keep the waterstop secure before and during pouring.
3. Joint Welding: Where continuous length is needed, join the ends using thermal welding (hot blade method) or solvent-based adhesives approved for PVC-based waterstops.
4. Formwork Integration: Integrate within formwork such that it remains exposed for joint overlap in multi-stage casting operations.
