BENTONITE BASED HYDROPHILIC WATERSTOP – SALINE GRADE

Surface Preparation
All surfaces to which SpECtite Swellseal Bentobar 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 Bentobar and apply onto the concrete surface, noting that it must be positioned inside the reinforcement cage with a minimum concrete cover of 75mm.

Press SpECtite Swellseal Bentobar firmly into place to ensure it covers 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 Bentobar 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 Bentobar in place using nailing guns, with nails at 300mm spacing approximately.

Do not use any damaged, deformed or swollen bars.
