Introducing Type NB190® Hydrophilic Waterstop from Earth Shield®

Introducing Type NB190® Hydrophilic Waterstop from Earth Shield®

Type NB190® is a modern, hydrophilic chloroprene rubber waterstop with unmatched durability and watersealing capabilities. Manufactured NON-BENTONITE, modified chloroprene rubber, Type NB190® more than doubles its original size (400% in 36 days) when exposed to water. This expansion creates an effective compression seal within joints of limited to no movement. Type NB190® can expand and reexpand 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.

Earth Shield® Modified Chloroprene Hydrophilic 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 Chloroprene Hydrophilic Waterstops are intended for non-moving construction joints only.

  • Comprised of NON-BENTONITE, modified chloroprene rubber
  • 100-plus year lifespan
  • Simple, low cost installation
  • Ideal for retrofit as well as new construction
  • Most profiles have a minimum of 231 ft (100 psi) resistance to water head pressure

Typical Applications

  • Water treatment plants
  • Wastewater treatment
  • Pipe penetrations
  • Storage tanks
  • Slab on grade
  • Foundations
  • Tunnel segments
  • ...and many more

Earth Shield® Modified Chloroprene Strip Applied (SA) Waterstop 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 reexpand an unlimited number of times without polymer degradation.
