N E T POUR IN PLACE WATERSTOP POLY SCRIM REINFORCEMENT RX 101T (Not to Scale) RX 101 RX 102 Bentonite Waterstop-RX ® is a concrete construction joint waterstop that provides a permanent seal by expanding upon contact with water. Waterstop-RX ® is an active sodium bentonite based waterstop that is designed to replace conventional passive PVC dumbbell waterstops, thus eliminating the requirement of split-forming and product seam welding. Waterstop-RX ® is manufactured in lightweight, flexible coils that can be installed in both hot and cold weather. The product is adhered to concrete, steel, and PVC (pipes) with CETSEAL sealant/adhseive; at or exceeding the required minimum distance from the exterior concrete surface. The key to Waterstop-RX ® is sodium bentonite. Sodium bentonite swells when in contact with water, forming an impermeable barrier. This swelling property allows Waterstop-RX ® to form a permanent pressure seal within the concrete joint, thus eliminating water migration over or along the waterstop.In addition to forming a positive pressure seal, the products expansion properties allow it to seal small cracks and void areas. Waterstop-RX ® is designed for structural concrete with a minimum of 3,000 psi. RX 101 and 101T , require a minimum 3" of concrete coverage. RX 102 requires a minimum concrete coverage of 2". RX 101 and 101T are designed for vertical and horizontal reinforced concrete 8" thick or greater, with two rows of reinforcing steel. RX 101 has more water resistance and will react slower in water or wet conditions before concrete is placed. RX 101T (trapezoidal) is recommended for shotcrete or gunite concrete construction, extreme hot weather and difficult applications. RX 102 is designed for vertical reinforced concrete 5" thick or greater; and horizontal reinforced concrete 4" thick or greater. RX 102 is designed primarily for concrete with one row of reinforcement. CETSEAL is a multi-purpose, low VOC, 100% solids, single component polyether moisture cure adhesive used to secure Waterstop-RX ® into position. Apply a continuous bead of CETSEAL to substrate then install Waterstop-RX ® before CETSEAL skins over and cures within 30 minutes. Adhesive yield will vary with use, substrate and application.
