SpECtite Swellseal Polybar is a hydrophilic
waterstop based on synthetic rubber for use in
construction joints subject to saline water
penetration. SpECtite Swellseal Polybar exhibits
good resistance to a wide range of chemicals (see
Chemical Resistance below) and presents a unique
characteristic of swelling many times its dry volume
when in contact with ground/saline water to form an
impenetrable gel capable of resisting hydrostatic
pressures of up to 60 meters.
