The WaterStop Gasket is intended to provide a cost-effective, watertight seal between HDPE and HP pipe and
concrete structures. It is currently available for pipe diameters of 12" through 60".
The WaterStop Gasket is a convenient field-installed seal that prevents water infiltration and exfiltration at manhole
connections. It meets the performance requirements of ASTM C923 (Standard Specification for Resilient Connectors
Between Reinforced Concrete Manhole Structures, Pipes and Laterals). The WaterStop Gasket, when grouted,
becomes a monolithic part of the manhole.
When ordering concrete structures, use the table below to select the minimum hole diameter needed to accommodate
the WaterStop Gasket.
