HDPE Waterstop Gaskets

HDPE Waterstop is a rubber ring which is compressed around the pipe circumference using stainless steel clamps, preventing infiltration and exfiltration between the HDPE Waterstop and the pipe. It is then either grouted into an existing structure, or has a new structure poured around it.

• Stainless steel clamps secure the connector to the pipe.
• The connector is placed to follow the arc of the manhole wall and the stainless steel clamp is placed straight across the confinement area.
• The pipe is placed in position and grouted in place using non-shrink patching compound OR
• The pipe is placed in position in the formwork and the structure is poured around it.
• After the mortar or concrete has set, the structure can be backfilled.

• The best alternative to solely using mortar joint compound.
• Adaptable to a variety of field and installation conditions.
• Can be installed with existing, new or poured-in-place structures.
• Nearly unlimited possibilities for pipe size, style or type.
