Self-injecting hydrophilic waterstop for concrete construction joints




WATERSTOP RX101 is a sodium bentonite based waterstop designed to stop water infiltration through cast-in-place concrete construction joints by expanding upon contact with water to form a positive seal against the concrete. The key to WATERSTOP RX101 effectiveness is its 75% sodium bentonite content, which provides superior expansion to seal and fill voids and cracks in the concrete. WATERSTOP RX101 is an active bentonite based waterstop that is designed to replace passive PVC/Rubber waterbars, thereby eliminating the requirement of special pieces, split-forming and seam welding. WATERSTOP RX101 has been successfully tested by independent testing firms to over 70m of hydrostatic water pressure, under both continuous immersion and wet/dry cycling. WATERSTOP RX101 is manufactured in light-weight, flexible coils that are easily installed by a single worker. The product is applied to concrete, steel and PVC (Pipes) with Revofix Mesh (preferred), and/or RX WB Adhesive. Coil ends are butted together – not overlapped – to form a continuous waterstop.




Applications include concrete construction joints, application to irregular surfaces, puddle-flange applications around cast-in penetrations, etc. WATERSTOP RX101 works in both continuous hydrostatic and intermittent hydrostatic conditions. WATERSTOP RX101 is designed for use in reinforced structural concrete, utilizing two rows of reinforcing steel, with a minimum thickness of 175 mm, providing the RX with no less than 75 mm concrete cover to all sides.
