Cetco Waterstop-RX Expanding Concrete Joint Waterstop

Cetco Waterstop-RX Expanding Bentonite Concrete Joint Waterstop

WATERSTOP-RX is available in multiple sizes and shapes to accommodate various joint configurations, including rectangular and half-circle cross-sections. It is supplied in lightweight, flexible coils that can be easily installed by a single worker without extensive training. Unlike traditional waterstops, it does not require split-forming, seam welding, or special transition pieces, simplifying the installation process. The bentonite composition allows it to seal cracks by using water pressure itself, making it highly effective in preventing leaks even under wet/dry cycling conditions. Independently tested for durability, it maintains performance under continuous immersion and extreme hydrostatic pressure, ensuring long-term reliability in concrete construction.

Cetco Waterstop-RX Expanding Bentonite Concrete Joint Waterstop Features

• Prevents water penetration in concrete joints, including vertical and horizontal structural joints and around pipes and penetrations.
• Expands upon contact with water to form a self-sealing barrier, effectively sealing cracks and voids.
• Designed for cast-in-place, reinforced concrete applications requiring hydrostatic pressure resistance.
• Capable of withstanding continuous and intermittent hydrostatic pressure up to 60 meters.
• Manufactured using an active bentonite composition that absorbs up to 15 times its volume in water.
• Available in multiple sizes and shapes, including rectangular and half-circle cross-sections.
• Supplied in flexible, lightweight coils for easy handling and installation.
• Eliminates the need for traditional PVC or rubber dumbbell waterstops, reducing installation complexity.
• Does not require split-forming, seam welding, or special transition pieces, saving time and labor costs.
