The WATERSTOP-RX Expanding Concrete Joint Waterstop is designed to prevent water penetration in cast-in-place, reinforced concrete joints, including vertical and horizontal applications and structural penetrations. Its active bentonite composition expands upon contact with water, forming a self-sealing barrier capable of withstanding continuous or intermittent hydrostatic pressure. This waterstop eliminates the need for traditional PVC or rubber dumbbell waterstops, offering a cost-effective and easy-to-install solution without requiring special pieces or complex installation methods. Independently tested to withstand over 60 meters of hydrostatic pressure, WATERSTOP-RX provides durable, reliable waterproofing for concrete construction projects.
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.
