SpECtite Swellseal Polybar
Polymer-based hydrophilic waterstop for saline environments.
The SpECtite Swellseal Polybar is an advanced polymer-based hydrophilic waterstop specifically designed for construction joints exposed to saline water. It features a remarkable ability to swell, creating an impenetrable gel that effectively resists hydrostatic pressures of up to 60 meters.
Offering excellent chemical resistance and flexibility, the SpECtite Swellseal Polybar is ideal for sealing irregular surfaces and preventing water ingress in various construction applications.

The SpECtite Swellseal Polybar is designed for efficient applications in various construction environments, ensuring optimal water sealing performance:
Surface Preparation:
All surfaces to which SpECtite Swellseal Polybar is to be applied should be clean and free of standing water. Any loose or flaking concrete must be removed. The preferred practice of scabbling joints is recommended.
Application:
Uncoil a length of SpECtite Swellseal Polybar and apply onto the concrete surface, ensuring it is positioned inside the reinforcement cage with a minimum concrete cover of 75mm. Press SpECtite Swellseal Polybar firmly into place to cover any surface undulations. In vertical installations, work from the base up to prevent any deformation or elongation.
Jointing:
Cut the ends of adjoining lengths of SpECtite Swellseal Polybar with a sharp tool to ensure a clean and square cut and press together for a close butt joint. Do not overlap.
Fixing:
Fix SpECtite Swellseal Polybar in place using nailing guns, with nails at approximately 300mm spacing. For installations on metal or plastic pipes, this can be achieved with a good quality contact adhesive.
Watch Points:
– SpECtite Swellseal Polybar must be confined within a concrete joint and not applied to exposed surfaces. – Exposed lengths of SpECtite Swellseal Polybar should be kept dry prior to concreting. Any pre-hydrated material should be replaced with new material. – SpECtite Swellseal Polybar should not be used in expansion or movement joints. – Where SpECtite Swellseal Polybar is to be used in areas subject to hydrocarbon contamination, use of SpECtite PVC Waterstops would be recommended.
