N E T POUR IN PLACE WATERSTOP NB 190 Hydrophilic Rubber Type NB190 is a modern, hydrophilic rubber waterstop with unmatched durability and watersealing capabilities. Manufactured NON-BENTONITE, modified chloroprene rubber, Type NB190 more than doubles its original size (400% volume swell) when exposed to water. This expansion creates an effective compression seal within joints of limited to no movement. Type NB190 can expand and re-expand unlimited times with virtually no loss of physical properties. Additionally, Type NB190 has excellent resistance to many chemicals, is heat-resistant, and can be safely used in drinking water. Basic Use Earth Shield Modified Chloroprene Strip Applied Waterstop is used as a fluid-tight diaphragm, running along the joint, for water treatment plants, waste water treatment plants, and fluid containment structures. Earth Shield Modified Chloprene Strip Applied Waterstops are intended for non-moving construction joints only. Unlike bentonite-based, strip applied waterstop, Earth Shield Modified Chloroprene Strip Applied Waterstops do not lose their structural integrity and can expand and re- expand an unlimited number of times without polymer degradation. Installation Install Earth Shield Modified Chloroprene Strip Applied Waterstops in all non-moving, concrete construction joints. Waterstop should be centered in, and run the extent of the joint. Adhere to concrete using Type NB190 Adhesive. Ensure that minimum concrete clear cover is three inches on all sides of the waterstop (two inches for Profile B).
